850 W ATX12V power supply

This 850 W ATX12V unit delivers up to 71 A on the single +12 V rail for high-end graphics cards and multi-core processors. Full modular cabling keeps the build tidy, while 100 % Japanese capacitors and 80 PLUS Platinum efficiency reduce heat and lower running costs. The 135 mm IP5X wing-blade fan and integrated heatsinks enable 0 dB cooling at low loads.

OLED monitoring and Aura Sync RGB

An integrated LIVEDASH OLED panel shows real-time power draw, temperatures and custom animations controlled through ASUS software. Addressable Aura Sync RGB lighting synchronises with compatible components across the ecosystem. The 160 mm depth fits most mid-tower and full-tower cases without clearance issues.

Single +12 V rail at 71 A

The single-rail design places the full 850 W on the +12 V line, so the limiting factor for modern GPUs is the 71 A ceiling. Builds that require more than two 6+2-pin PCIe connectors or sustained loads above this current will need a higher-capacity unit.

Questions about this item

Will the 160 mm length and standard ATX 24-pin connector fit my older mid-tower case and motherboard?

Yes, the 160 mm depth matches typical ATX bays and the 24-pin main connector is the long-standing standard for current and legacy motherboards.

How can I confirm the 135 mm wing-blade fan and OLED panel are functioning after installation?

The OLED panel shows live wattage, voltage and temperature; the fan stays off under light load and spins up audibly when power draw increases.

Which cables come in the box with this fully modular 850 W unit and what must I buy separately?

The package includes the PSU, detachable 24-pin, two 6+2-pin PCIe and peripheral cables plus mounting screws; no extra cables are needed for a typical build.
