AORUS P850W 850W ATX power supply

The AORUS P850W is a fully modular ATX 12V v2.31 unit rated for 850 W maximum output. It targets builders who need reliable delivery for high-performance desktop systems. The single +12V rail design simplifies cable planning for demanding graphics cards and CPUs. Full modularity lets you connect only the cables your build requires.

160mm depth with double ball bearing fan

At 160 mm long the chassis fits standard ATX bays while housing a 135 mm double ball bearing fan. The fan includes a stop function that halts rotation at low load for silent operation. Six PCIe 6+2-pin connectors and six SATA power plugs support multiple GPUs and storage drives. Two CPU 4+4-pin cables and a 20+4-pin motherboard connector cover modern platform needs.

80 PLUS Gold efficiency and protection suite

80 PLUS Gold certification guarantees 90 percent efficiency at typical 50 percent load, reducing waste heat and electricity cost. Active PFC corrects power factor across the 100 to 240 V input range. A comprehensive protection set includes OVP, OPP, SCP, UVP, OCP and OTP. Hold-up time exceeds 16 ms at full load on 115 V, and MTBF is rated beyond 100000 hours.

Questions about this item

What does the ATX 12V v2.31 standard mean for the maximum power this unit can deliver?

The unit complies with ATX 12V v2.31 and is rated for a maximum output of 850 W, so that is the practical ceiling for sustained load.

How much clearance does the 160 mm length require inside the case?

The power supply measures 160 mm long, so the case must provide at least that much depth behind the motherboard tray for a proper fit.

How do you install the fully modular cables, and which step is most often missed?

Connect only the cables your build needs — 20+4-pin motherboard, two 4+4-pin CPU, up to six 6+2-pin PCIe, six SATA, five 4-pin peripheral and two floppy — then route and secure them; the step most often missed is leaving unused cables in the box instead of plugging them in.
