Cooler Master 850 W ATX12V PSU

This Cooler Master unit delivers 850 W of fully modular power for high-performance desktop builds. The ATX12V design supports modern multi-rail loads while the compact 160 mm length fits most standard cases. A 135 mm fan runs under Cybenetics A- acoustics for quiet operation. It is suited to enthusiasts who want clean cable routing and reliable efficiency.

Platinum efficiency and connector headroom

80 PLUS Platinum certification guarantees at least 92 percent efficiency at typical loads, reducing waste heat and electricity cost. Six 6+2-pin PCIe connectors and four 4-pin CPU connectors provide ample headroom for dual high-end graphics cards and power-hungry processors. Twelve SATA connectors handle large storage arrays. Protection circuits include OPP, OVP, OCP, UVP, SCP, OTP, surge and inrush protection.

Fully modular build integration

Full modularity lets you connect only the cables your build needs, improving airflow and simplifying assembly. The 24-pin ATX, EPS 4+4-pin and EPS 8-pin cables attach directly to the PSU housing. Active PFC accepts 100-240 V input at 50/60 Hz for worldwide compatibility. A built-in information display panel shows real-time status. MTBF exceeds 100,000 hours for long-term confidence.

Questions about this item

Will the 160 mm depth and 24-pin ATX connector fit my older ATX12V case and motherboard?

The 160 mm length matches standard ATX12V dimensions and the 24-pin main connector is the current ATX standard, so it will install in any compatible case and motherboard.

How can I confirm the 135 mm ARGB fan and built-in display panel are operating correctly after installation?

The display panel shows real-time power draw and the fan spins up according to the semi-passive curve; both activate as soon as the system powers on.

Which cables are included and what must I purchase separately for a typical build?

The box supplies the fully modular PSU, a 24-pin ATX cable, two EPS cables (4+4-pin and 8-pin), six PCIe 6+2-pin cables, twelve SATA cables and four peripheral 4-pin cables; no extra cables are needed for standard configurations.
