FAQ: Frequently Asked Question
FAQ – Frequently Asked Questions
1. Is the CX650 fully-modular or fixed-cable?
It’s a fixed-cable (non-modular) power supply; pick the CX650 M if you want semi-modular cabling.
2. How many PCIe connectors does it have for GPUs?
One twin-headed lead with 2 × 6+2-pin PCIe plugs, enough for cards up to an RTX 4070 / RX 7800 XT that need two 8-pins.
3. Is there an EPS/CPU 8-pin lead for modern motherboards?
Yes—one 4+4-pin EPS12V connector on a dedicated 600 mm cable.
4. What warranty does Corsair give?
The entire CX Series, including the CX650, is backed by a 5-year manufacturer warranty.
5. How quiet is the fan—does it have zero-RPM mode?
The 120 mm rifle-bearing fan is thermally controlled but never stops; there is no zero-RPM mode (≈ 26 dBA at 50 % load).
6. Will 650 W run a Ryzen 7 5800X3D + RTX 4070 build?
Yes—total draw is about 410 W peak; the CX650 leaves 35–40 % headroom and supplies two 8-pin PCIe plugs for the GPU.
7. What are the physical dimensions—will it fit an mATX case?
Compact ATX size: 150 × 86 × 140 mm (W × H × D), ideal for most micro-ATX chassis.
8. Is the unit globally compatible (110–240 V)?
Yes—active PFC accepts a 100–240 V AC input automatically; no voltage switch required.
9. What efficiency rating and real-world efficiency should I expect?
80 PLUS Bronze; about 85 % efficiency at 50 % load on 115 V and ≈ 88 % on 230 V mains.
10. Which safety and protection circuits are included?
OVP, UVP, OPP, SCP, OTP and OCP on the 12 V rail—fully compliant with IEC/EN 62368-1.
11. Difference vs. CX650 M?
Same platform and rails; CX650M adds semi-modular flat cables and costs roughly £10–15 more.
12. What is the MTBF and expected lifespan?
Rated for >100,000 h MTBF at 25 °C; rifle-bearing fan and 105 °C primary capacitors target 5+ years of normal use.
