80 Plus Gold + Cybenetics Gold
With dual 80 Plus Gold and Cybenetics Gold certification, the ASUS Prime 850W Gold delivers up to 92% efficiency — resulting in less heat, reduced fan noise, and increased reliability . Moreover, low-ESR capacitors and premium components ensure stable, long-term operation.
ATX 3.1 & PCIe 5.1 Compatible
The Prime Gold series meets the stringent requirements of the ATX 3.1 standard and supports PCIe 5.1 graphics cards. It supports total power excursions up to twice the rated power and GPU power excursions up to three times the rated power — ensuring rock-solid stability for your PC . Additionally, a bundled 16-pin PCIe cable delivers up to 600W to next-gen GPUs .
Premium Etched Cables
Made from tin-plated oxygen-free copper, these etched cables are easily flexible during installation and operate at temperatures 50°C below the safety limit when routed for cable management . Furthermore, they meet the rigorous standards of UL1581 flame test and UL758 certification, ensuring exceptional safety and a smooth PC DIY experience .
16-pin PCIe Cable: Insert Fully
When using the bundled 16-pin PCIe cable for RTX 50 series or RX 9000 series graphics cards, ensure it is fully inserted until you hear a click. Partial insertion can cause high resistance, overheating, and potential damage to both the PSU and GPU. Additionally, avoid sharp bends near the connector — maintain a minimum 3.5cm clearance from the connector for safe cable routing. The fully modular design lets you use only the cables you need, reducing clutter and improving airflow.
Dual-Ball Fan Bearings
Exemplary cooling is provided by a 135mm fan spinning on a dual-ball bearing setup that lasts up to twice as long as a sleeve bearing design — with an 80,000-hour lifespan . Furthermore, upgraded PCIe connectors feature superior copper pins with advanced thermal conductivity, resulting in a 29% reduction in connector temperatures (up to 12.28°C) .
Versatile Black & White Housing
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 . Moreover, the space-saving, secure design complements any PC aesthetic — whether you’re building a stealth-black rig or a white-themed showcase.
8-Year Warranty Included
We’re so sure about the reliability of the ASUS Prime 850W Gold that we back it with an 8-year warranty . Consequently, you get peace of mind for your high-performance build, backed by ASUS quality and durability.
