850 W ATX power supply for high-performance builds

This fully modular ATX12V unit delivers 850 W of continuous power with 80 PLUS Platinum efficiency. A single +12 V rail rated at 70 A supplies clean current to demanding components. Load regulation stays under 0.5 % for stable voltage under heavy loads.

Ideal for multi-GPU systems needing six PCIe

Six 6+2-pin PCIe cables and ten SATA power connectors support multiple graphics cards and storage arrays. The 170 mm length fits most mid-tower and larger cases. Builds requiring only a few drives or a single GPU can use a smaller, less expensive unit.

Fanless mode via premium hybrid fan control

A 135 mm fluid dynamic bearing fan stops completely at low load when S3FC mode is selected. The rear switch toggles between fanless and constant cooling profiles without software. Silence-focused builders gain true zero-fan operation; noise-tolerant users may prefer a simpler design.

Kysymyksiä tästä tuotteesta

How do I install the PRIME PX-850 and what step is often missed?

Mount the 170 mm ATX unit, connect the 20+4 pin main cable plus the two CPU 8/4 pin cables, then plug only the modular leads you need; the step people skip is pressing the fan-control button to choose S2FC or S3FC before first power-on.

What maintenance or replacement will the PRIME PX-850 need later?

The 135 mm fluid-dynamic-bearing fan is the only moving part; after many years it can be swapped for another 135 mm unit, while the rest of the supply is rated for 150000 hours MTBF at 25 °C excluding the fan.

What limit appears first under sustained heavy load on the PRIME PX-850?

The single +12 V rail delivers up to 70 A; if the combined GPU and CPU draw exceeds that current the over-current protection will trip before the 850 W total rating is reached.
