The be quiet! Pure Power 13 M 1200W is a fully modular high-performance ATX 3.1 desktop power supply for gaming PCs, creator workstations and other demanding systems. It provides 1200W continuous output, a native 600W 12V-2x6 graphics-card connection, four PCIe 6+2-pin connectors, semi-passive cooling and 80 PLUS Gold efficiency.

The UK model is BP029UK. The Memox SKU is PSBEQ-BP029UK and the listed EAN/UPC is 4260052193723.

It is rated for 1200W of continuous output. This is the sustained capacity to use when planning the system.

be quiet! lists 1250W peak power. Peak power is not the same as a 1250W continuous rating.

ATX 3.1 is a current desktop power-supply specification covering electrical behaviour, modern GPU power connections and the ability to tolerate short high-power excursions from current CPUs and GPUs.

Yes. be quiet! specifies full PCIe 5.1 GPU compatibility and supplies both a native 12V-2x6 cable and conventional PCIe 6+2-pin GPU connections.

12V-2x6 is the updated 16-pin high-power PCIe graphics-card connector used by many recent GPUs. It is intended to improve connector engagement compared with the earlier 12VHPWR design.

The Pure Power 13 M 1200W is officially rated to provide up to 600W through its native 12V-2x6 graphics-card connection.

Yes. be quiet! lists 600W as the maximum combined power for the supplied 12V-2x6 connection. The complete system must still remain within the PSU's 1200W continuous rating.

They belong to the same 16-pin PCIe power-connector family and current 12V-2x6 cables are intended for compatible modern cards. Always follow the exact graphics-card manufacturer's instructions.

When the graphics card accepts a native PCIe Gen 5 16-pin cable and the PSU cable meets the card's requirement, the native cable usually avoids the extra connections introduced by a multi-8-pin adapter.

Insert it straight and firmly until the plug is fully seated and flush with the graphics-card socket. Do not leave a visible gap, pull it sideways or force the case panel against the connector.

Yes. A poorly seated high-current connector can increase electrical resistance and heat. Always verify full insertion before powering the system.

No. Avoid a tight bend or strong sideways pressure immediately beside the connector. Give the cable room to leave the GPU naturally before routing it.

It should not apply strong pressure to the plug or create a severe bend. Check GPU width, case clearance and cable routing before closing the panel.

Yes. It provides four PCIe 6+2-pin GPU connectors in addition to the native 600W 12V-2x6 connection.

Yes. The 6-pin and 2-pin sections join together to make a standard 8-pin PCIe graphics-card connector.

Yes. Older GPUs using standard 6-pin or 8-pin PCIe power can use the supplied PCIe 6+2-pin connectors.

The PSU has four PCIe 6+2-pin connectors, so the connector count is sufficient. Follow the graphics-card manufacturer's instructions regarding cable runs.

The PSU provides four 6+2-pin GPU connectors. Confirm the exact GPU's cabling requirements and total system load before installation.

Where the graphics-card manufacturer asks for independent PCIe feeds, follow that guidance rather than relying on improvised splitters.

Do not use an unapproved splitter simply to exceed the supplied connector arrangement. Use only cables and adapters approved for the PSU and graphics card.

The official specification lists one 4+4-pin CPU connector and one separate 8-pin CPU connector.

Yes. The 4+4-pin CPU lead can form one 8-pin EPS connection and the separate P8 lead provides a second 8-pin CPU connection.

Yes. The 4+4-pin lead can be split when needed, while the separate 8-pin EPS lead can populate the main 8-pin socket.

Not always. Some enthusiast boards use extra EPS sockets mainly for extreme CPU power or overclocking. Follow the motherboard manual.

Yes. One 20+4-pin ATX motherboard power connector is included.

The official specification lists six SATA power connectors.

The PSU includes two PATA/Molex power connectors.

No dedicated FDD/floppy connector is listed.

Yes. All component power cables are detachable from the PSU.

A modular PSU reduces unused cable clutter, simplifies installation and can improve airflow and appearance inside the case.

Yes. Connect only the cables your build requires and store the unused original cables safely.

No. Modular PSU pinouts are not universal and an incompatible cable can damage components.

Only when be quiet!'s compatibility information explicitly confirms that exact cable and PSU combination. When unsure, use the cable set supplied with the new PSU.

The component-end connector may look standard while the PSU-end wiring differs between models, potentially placing the wrong voltage on a component.

Only use a custom cable set specifically verified for the exact Pure Power 13 M model or a compatibility list that explicitly includes it.

Quality extensions can be attached to the component end when properly rated, but they add another connection and must not be used to exceed the original cable ratings.

be quiet! lists both sleeved and flat modular cables in the cable set, depending on cable type.

be quiet! lists a maximum cable length of up to 95cm across the cable set, while the motherboard cable is listed at 55cm.

They suit many full-tower builds, but very large dual-chamber cases can require long routing paths. Measure the planned cable route first.

The PSU measures 160 x 150 x 86mm, excluding modular cables.

be quiet! lists the PSU weight at approximately 2.69kg.

It will fit cases that accept a standard ATX PSU and provide enough room for its 160mm length plus modular cable clearance.

Yes, if the case supports a full-size ATX PSU and has enough room for cables.

Only when the Mini-ITX case accepts an ATX power supply. Many compact ITX cases accept SFX or SFX-L only.

No. It is a standard ATX PSU.

Yes. A 160mm chassis is relatively compact for a 1200W high-power ATX unit.

The official specification lists 100-240V AC at 50-60Hz.

Yes. UK mains is within the supported input range. Use the correct approved UK mains lead supplied for the regional model.

be quiet! lists 15A / 7.5A input current depending on mains voltage.

The specification lists a power factor above 0.97 at full load, consistent with modern active-PFC operation.

Yes. be quiet! lists Modern Standby support.

The official specification lists less than 0.1W PSU standby consumption under the relevant conditions.

be quiet! lists operation up to 40°C ambient temperature.

The manufacturer lists an average lifetime above 100,000 hours at 25°C. This is a design-life figure rather than a guaranteed lifespan for every unit.

80 PLUS Gold is an efficiency certification. Higher efficiency reduces the amount of input energy wasted as heat under the relevant test conditions.

be quiet!'s detailed table lists approximately 75.9% at 2% load, 91.2% at 10%, 93.4% at 20%, 93.6% at 50% and 90.8% at full load on 230V input.

The marketing headline and detailed table use slightly different rounding. The model is officially 80 PLUS Gold certified.

No. It draws only what the computer requires plus conversion losses.

Not simply because of its maximum rating. Actual wall consumption is driven mainly by the components and PSU efficiency at the operating load.

Yes. be quiet! lists Cybenetics ETA Gold efficiency certification and Cybenetics LAMBDA A acoustic classification.

It uses a silence-optimised 120mm be quiet! fan with a rifle bearing and four-pole motor.

be quiet! lists a maximum fan speed of 2700RPM.

Yes. Pure Power 13 M uses semi-passive zero-RPM cooling, so the fan can stop completely under low-load conditions.

Yes. The semi-passive behaviour is controlled automatically by the PSU.

No user fan-control interface is listed. Cooling is controlled internally.

The Pure Power 13 M does not list a user-selectable fan-mode switch. Fan-stop behaviour is automatic.

Yes. In a semi-passive design the fan may remain stopped while internal temperature and load are low.

be quiet! does not publish one fixed load percentage at which the fan always starts. It depends on internal temperature and operating conditions.

The official table lists approximately 9.8dB(A) at 10% and 20% load, while zero-RPM conditions can stop the fan entirely.

be quiet! lists approximately 11.6dB(A) at 50% load.

The official specification lists approximately 32.3dB(A) at 100% load.

Case acoustics, ambient temperature, component heat and installation all affect perceived noise. Electrical coil noise can also be separate from fan noise.

Coil whine is high-frequency electrical vibration that can occur in inductors inside a PSU, graphics card or motherboard and can vary with load or frame rate.

No. Individual user reports do not mean every unit will exhibit audible coil whine.

Identify whether the sound is actually from the PSU rather than the GPU. If it is unusually loud or accompanied by instability, burning smell or crackling, power down and contact support.

A relay or switching event can create a brief click during startup or shutdown. Repeated clicking with failed booting should be investigated.

The official specification lists over-temperature, over-current, over-power, short-circuit, over-voltage, under-voltage, surge and inrush-current protection.

OCP is over-current protection and is designed to shut the PSU down if current exceeds a safe threshold.

OPP is over-power protection and helps protect the PSU if total output is driven beyond safe limits.

OTP is over-temperature protection and can shut the PSU down if internal temperature becomes unsafe.

SCP is short-circuit protection and is designed to react when an electrical short is detected.

OVP is over-voltage protection and UVP is under-voltage protection.

The PSU includes circuitry intended to manage supported surge and startup inrush events. It is not a substitute for whole-building lightning protection.

Yes. The Pure Power 13 M 1200W uses one high-performance 12V rail.

The official table lists up to 100A on the 12V rail, with 1200W maximum combined 12V output.

The official specification lists a maximum combined 120W for the 3.3V and 5V rails.

be quiet! specifies LLC resonant conversion with synchronous rectification and DC-to-DC regulation.

LLC is a resonant-converter design used to improve efficiency, switching behaviour and voltage regulation.

The PSU creates its main 12V output and derives lower-voltage rails through DC-to-DC converters, helping maintain regulation across modern load patterns.

No. The official table marks digital control as not included.

Hold-up time is the short period the PSU can maintain output after incoming mains disappears. be quiet! lists about 19.11ms at full load and 25.54ms at 80% load.

Yes. be quiet! states that it can handle short power excursions up to twice its rated power in accordance with modern ATX requirements.

No. It refers to extremely short transient excursions. The continuous output remains 1200W.

High-performance GPUs can change load very rapidly and momentarily demand more power than their average consumption.

For the RTX 5090 Founders Edition, NVIDIA's guide specifies a 1000W minimum system PSU and either four independent PCIe 8-pin cables with the adapter or one 600W-or-greater PCIe Gen 5 16-pin cable. This PSU provides 1200W and a native 600W 12V-2x6 connection, but partner-card requirements can differ.

The PSU cable is rated for 600W, matching the 600W-or-greater PCIe Gen 5 cable requirement stated in NVIDIA's RTX 5090 Founders Edition guide. Ensure the connector is fully seated.

The PSU provides four 6+2-pin connectors, but NVIDIA's Founders Edition guide calls for at least four independent 8-pin PCIe cables when using its adapter. The native 600W 12V-2x6 cable is the cleaner option when supported.

Yes in power-capacity terms for typical RTX 5080 systems. Confirm the exact graphics-card manufacturer's recommended PSU wattage and connector requirements.

Yes. 1200W provides substantial capacity for an RTX 5070 Ti system, though a lower-wattage quality PSU may also be sufficient.

Yes for many RTX 4090 systems when the exact card and complete build meet manufacturer recommendations.

Yes. The 1200W capacity gives ample headroom for most RTX 4080 SUPER builds.

Yes. AMD specifies a 750W minimum PSU recommendation for the reference RX 9070 XT, so this 1200W unit provides substantial headroom.

Yes. AMD lists a 650W minimum PSU recommendation for the reference RX 9070, making 1200W far above the minimum.

Yes for systems that meet the exact card manufacturer's connector and PSU recommendations.

Yes. It can power high-end Ryzen 9 systems when the complete build stays within 1200W.

Yes. The two CPU power connections and 1200W capacity suit many high-end Intel systems.

It can be a strong match because it offers 1200W continuous power and a native 600W 12V-2x6 connection. Check the exact parts with a PSU calculator and manufacturer guidance.

1200W provides substantial capacity, but unrestricted or overclocked CPU and GPU settings can raise power sharply. Verify the exact GPU and motherboard requirements.

Yes, but overclocking can increase power consumption dramatically. Estimate worst-case CPU and GPU demand and keep sensible headroom.

Yes. Its 1200W output, dual CPU power connectors and high GPU capacity suit many creator and workstation builds.

Yes. It is rated for 1200W continuous output and is intended for sustained operation within specification.

It can suit single high-end GPU AI workstations and some multi-device configurations, provided total power and connector requirements remain within specification.

Possibly, but multi-GPU suitability depends on each card's power and connector requirements. Connector count alone does not guarantee support.

This should not be assumed. Two very high-power GPUs plus a high-end CPU can exceed practical 1200W system capacity and connector requirements. A specialised higher-wattage workstation PSU is more appropriate.

Often yes. A mainstream CPU and mid-range GPU may be better served by a 650W, 750W or 850W quality PSU.

Choose 1000W when the complete system leaves comfortable headroom. Choose 1200W for RTX 5090-class configurations, heavy CPU loads, overclocking or a larger upgrade margin.

850W is enough for many high-performance systems, while 1200W is aimed at extreme GPUs, power-hungry CPUs and larger upgrade headroom.

No. A PSU does not increase CPU or GPU performance by itself; it provides stable power.

Extra capacity can help if the previous PSU was near its limit, but overclocking stability also depends on cooling, motherboard VRMs, silicon quality and voltage settings.

Use the exact CPU, GPU, drives, fans, pumps and expansion devices in the be quiet! PSU calculator and compare with the GPU manufacturer's recommendation.

There is no single percentage for every PC. The system should remain comfortably below the continuous limit under realistic worst-case loads.

No. The PSU can safely operate at low load, although efficiency is lower at extremely light load than around its optimum range.

The official 230V table shows its highest listed efficiency around 50% load, approximately 93.6%.

Yes. Semi-passive fan stop, high efficiency and a temperature-controlled 120mm fan are specifically designed to reduce noise.

It can be very quiet at low and moderate loads, but a 1200W PSU under sustained heavy load must actively cool itself.

Yes, within its operating specifications and with adequate ventilation.

Yes, though 1200W is larger than necessary for most low-power home servers.

Yes, but the UPS must support the computer's actual wattage and active-PFC behaviour. For a high-end system, a suitably rated pure-sine-wave UPS is usually preferable.

Not necessarily; it must cover the PC's actual maximum draw with headroom. A build that can genuinely approach 1000-1200W requires a very large UPS.

Use only a high-quality properly rated strip, avoid daisy-chaining and do not overload the circuit.

If the case has a filtered bottom PSU intake with adequate clearance, the fan normally faces downward. Otherwise follow the case manufacturer's airflow guidance.

Yes when the case design calls for it and the intake remains unobstructed.

Allow enough space for modular plugs to sit straight and for cables to bend gradually.

Yes. Higher intake temperature can make the cooling fan run faster and more often.

Yes. A clogged case filter can restrict airflow and increase PSU temperature and fan speed.

Turn off the PC, unplug the mains lead and clean only from the outside using gentle air and a soft brush around the grille or filter.

No. Power supplies contain capacitors that can retain dangerous voltage even after unplugging.

Check the rear power switch, mains lead, 24-pin motherboard cable, CPU EPS cables, front-panel power button lead, GPU power and modular connections.

Check GPU power seating, 12V-2x6 engagement, overclocking, temperatures, motherboard power, cable connections and actual load.

Power down and verify GPU seating, monitor connection, 12V-2x6 insertion, PSU cable choice, motherboard BIOS and graphics drivers.

Shut down and inspect the connector for incomplete insertion, discoloration, deformation or cable stress. Do not continue using a visibly damaged connector.

The Pure Power 13 M is not a digitally monitored PSU and does not provide a USB telemetry interface.

No. The PSU has a black functional design without RGB lighting.

No. It does not include an LCD or power display.

No. The Pure Power 13 M uses a single 12V rail and does not include the multi-rail/single-rail overclocking key found on some Dark Power models.

No. The PSU fan is internally powered and controlled.

No. Opening the PSU is unsafe and may void warranty coverage.

A jump-start test can show whether a PSU starts, but it cannot confirm operation under load and can be hazardous if performed incorrectly.

A basic tester can check whether main rails and the power-good signal are present, but it cannot fully reproduce demanding transient loads.

Yes. be quiet! lists mounting screws in the package.

Yes. Cable ties are included.

The official table lists standard cable ties but not Velcro cable ties.

The BP029UK regional model is intended for the UK market. Use only an approved, correctly fused UK mains lead.

be quiet! lists a 10-year manufacturer's warranty, subject to its warranty conditions and proof-of-purchase requirements.

Yes. Keep the purchase invoice and product serial details for any future warranty claim.

Opening a mains power supply is unsafe and can affect warranty eligibility. Do not remove the enclosure.

No. Shut down, switch off and disconnect mains power before adding, removing or reseating modular cables.

CPU EPS and GPU PCIe plugs are wired differently. Use the labelled cable for its intended component and never force a connector.

Not directly. Use the supplied PCIe 6+2-pin cables for a graphics card that accepts standard 6-pin or 8-pin power.

Only through the exact adapter arrangement approved by the graphics-card manufacturer. The native 600W 12V-2x6 cable is usually the cleaner option.

Yes. 600W is the maximum rating for that GPU connection, while 1200W is the PSU's continuous total output rating.

Its total 12V capacity is 1200W, but every connector, cable and component limit must also be respected. Do not design a system to operate continuously at absolute maximum.

Modern systems draw most CPU and GPU power from 12V, so this model is designed with a high-capacity single 12V rail capable of the full rated output.

Yes. A properly designed single-rail PSU uses protection circuitry while allowing flexible current distribution across CPU and GPU loads.

No. The 1200W Pure Power 13 M is specified as single-rail only.

No. The unit also supports conventional GPUs through its PCIe 6+2-pin connectors.

Yes. PSU compatibility depends on the card's power connectors and requirements, not the PCIe generation of the motherboard slot.

No. It improves power-delivery compatibility and transient handling, not frame rate by itself.

EPS12V is a power-supply specification for higher-power systems. This unit lists EPS 12V version 2.92 support and provides two CPU power connections.

A PSU is operating-system independent. It can power a Windows 11 PC as long as the hardware itself is compatible.

Yes. The PSU does not depend on operating-system drivers.

No. It operates entirely as hardware.

It provides six SATA power connectors, so six compatible SATA devices can be powered if the cable layout suits the build.

Yes when the cooler, pump or hub is designed for SATA power.

Yes. The PSU includes two PATA/Molex connectors.

Yes within connector and system power limits, but large storage systems should consider hard-drive startup current.

Yes. Its capacity and SATA/Molex outputs can support pumps, controllers and many fans within the overall power limit.

Yes. High-end editing systems with powerful GPUs, many drives and high-core-count CPUs can benefit from its capacity.

Yes. Long CPU/GPU renders are sustained workloads and the PSU is rated for continuous output within specification.

Yes. Its high capacity suits development systems with powerful CPUs, GPUs and multiple drives.

Potentially. Some Threadripper boards have very high power and EPS requirements, so verify the exact motherboard and CPU first.

Yes. ATX 3.1, native 600W 12V-2x6, four conventional PCIe connectors and 1200W capacity provide strong upgrade flexibility.

No. Future products can introduce new connector, power or platform requirements. It means strong current headroom, not guaranteed indefinite compatibility.

Pure Power 13 M moves to ATX 3.1 and 12V-2x6 and adds semi-passive zero-RPM cooling. Pure Power 12 M was based on the earlier ATX 3.0/12VHPWR generation.

Choose 1000W when the system leaves comfortable headroom. Choose 1200W for RTX 5090-class configurations, heavy CPU loads, overclocking or more upgrade margin.

Both are high-quality 1200W modular units. Straight Power 12 is positioned as a more premium Platinum-efficiency series with a 135mm Silent Wings fan, while Pure Power 13 M focuses on ATX 3.1, semi-passive operation and value.

Pure Power 13 M is an 80 PLUS Gold semi-passive unit with one 600W 12V-2x6 connection and four PCIe 6+2 connectors. Power Zone 2 1200W moves to Platinum efficiency, a 140mm fan and two angled 12V-2x6 connections.

Dark Power 14 is be quiet!'s higher-end Titanium-efficiency option with more advanced cooling and selectable operating modes. Pure Power 13 M is the more value-focused 1200W choice.

For many gaming systems, yes if the additional efficiency and premium features of a Titanium model are not worth the higher price.

Yes. Efficiency certification is not a direct measure of capacity or overall quality. This model is designed as a high-performance ATX 3.1 PSU.

First ensure enough wattage and the correct connectors, then compare efficiency, noise, warranty and price.

No. Gold, Platinum and Titanium describe efficiency tiers, not output capacity.

Yes. Less conversion loss means less waste heat at the same output load.

Usually. Lower internal temperature can allow slower fan operation or longer zero-RPM periods.

The high maximum speed provides cooling reserve for demanding conditions. Under lighter loads the fan runs much slower or stops.

Yes. Semi-passive control can start the fan when internal temperature or load reaches the cooling threshold.

Yes, once internal conditions allow it. Exact timing is automatic.

Some warmth is normal. Excessive heat, burning smell, smoke or repeated protection shutdowns are not normal.

Switch off the PC immediately, disconnect mains power and do not continue using the PSU until the source has been inspected.

Yes. A short circuit or abnormal current draw in another component can trigger PSU protection.

Yes. CPU, RAM or GPU instability can cause resets and crashes that resemble power issues.

Yes. Test the GPU at default settings before blaming the power supply.

Yes. No-POST, black screens and crashes can come from many components. Troubleshoot systematically.

Yes. Poor earthing, loose wiring or an overloaded circuit can cause power problems and should be checked professionally.

Yes. A standard rear mains power switch is included.

It is not necessary for normal daily use, but switching off is appropriate before hardware work or long periods of disuse.

Yes. Shut the PC down, switch off the PSU and disconnect the mains lead before installing or removing internal components.

Yes if the case is designed for vertical PSU mounting and provides proper ventilation.

Yes. Its 160mm length and fully modular cables suit many dual-chamber cases, subject to cable clearance.

Yes electrically, but the PSU itself has no RGB lighting.

Only if the route does not create a sharp bend or pull on the GPU connector. Prioritise safe connector seating over hidden routing.

Use only an adapter or cable solution explicitly approved for the exact GPU and PSU arrangement. Additional high-current connections add another potential failure point.

The standard Pure Power 13 M 1200W specification lists one 12V-2x6 cable but does not advertise the dual angled 12V-2x6 arrangement found on Power Zone 2 1200W.

Check the GPU's recommended PSU wattage and connector, CPU power, motherboard EPS sockets, case support for a 160mm ATX PSU and whether 1200W is appropriate for the build.

It is best for high-end gaming and creator systems using powerful GPUs, demanding CPUs, multiple drives or overclocking where ATX 3.1, a native 600W 12V-2x6 connection and substantial headroom are valuable.

It is not ideal for SFX-only cases, ultra-low-power office PCs or budget builds that will never use its capacity. Buyers needing two native 12V-2x6 outputs or Titanium efficiency should compare higher-tier models.

Yes for a new high-end build that genuinely benefits from 1200W capacity. ATX 3.1, native 12V-2x6, modular cables, semi-passive cooling and a 10-year warranty align well with current enthusiast hardware.

Its key strengths are 1200W continuous output, ATX 3.1 compliance, a 600W native 12V-2x6 connection, four PCIe 6+2 plugs, two CPU power connections, compact 160mm length, semi-passive cooling and a 10-year warranty.

The main limitation is that 1200W may be unnecessary for ordinary PCs, and the PSU provides one native 12V-2x6 connection rather than the two found on some higher-tier 1200W models.
