850W ATX 3.1 Power Supply

This fully modular ATX 3.1 unit delivers 850W from a single +12V rail. It targets builders who need PCIe 5.1 readiness and high efficiency in a 150mm deep chassis. Cybenetics Gold and 80 PLUS Gold certifications confirm >90% typical efficiency. The ribbon cable set keeps routing clean in compact or showcase builds.

Compatibility Checklist

Verify that your case accepts a 150mm long PSU and that the 20+4Pin main connector matches your motherboard. Count required EPS, PCIe, SATA and peripheral plugs against the supplied set: two 4+4Pin EPS, three 6+2Pin PCIe, one dual 8Pin to 12V-2x6, eight SATA and four four-pin peripheral connectors. Ensure your mains supply falls within the 100–240V 50/60Hz input range.

Build Quality and Daily Use

A 140mm fluid dynamic bearing fan with a copper shaft runs in semi-fanless mode at low load, reducing noise during idle work. Full modularity means only necessary cables stay inside the case, improving airflow and simplifying upgrades. The protection suite covers OVP, OCP, OPP, SCP, UVP, OTP, NLO and SIP for stable operation under transient spikes.
