Overview

PRIME PERFORMANCE

With 80+ Gold certification, dual ball bearing fans, and an 8-year warranty, the ASUS Prime series PSU brings efficient and durable power delivery to high-performance workstations, all-round PCs, and gaming rigs.

DUAL BALL FAN BEARINGS

Exemplary cooling is provided by a 135mm fan spinning on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.

80 PLUS GOLD CERTIFICATION

The ASUS Prime 850W Gold PSU features efficient, low-ESR capacitors to ensure efficient operation - affording it 80 PLUS® Gold status. This means it delivers up to 92% efficiency, resulting in less heat, reduced fan noise, and increased reliability.

ATX 3.0 COMPATIBLE

The latest power specification updates have landed. ATX 3.0 ushers in tighter voltage and current regulation guidelines for next-gen hardware - and ASUS Prime 850W Gold steps ahead of the curve by being fully compliant. A 16-pin PCIe cable that is compatible with PCIe Gen 5.0 graphics cards is bundled with the PSU, bringing large-scale capabilities.

CHOOSE YOUR STYLE

Two sides of the housing are painted white, and two sides are painted black, allowing you to orient the PSU to match your preferred build theme.

8-YEAR WARRANTY

We're so sure about the reliability of the ASUS Prime 850W Gold that we back it with an 8-year warranty.
