ASUS ROG STRIX 850W Gold power supply unit 20+4 pin ATX ATX Black

Frozen Silence
The ROG Strix Series PSUs bring high-end cooling and premium components together for an ultra-quiet high-performance product aimed at core gamers. Massive ROG heatsinks trickle down from the mighty ROG Thor series and Axial-tech fan design from our premium NVIDIA RTX™ graphics cards also make an appearance. Below the surface, low RDS (on) MOSFETs and premium Japanese capacitors take on power delivery with ease. The result is an incredibly quiet and efficient power supply with the reserves to handle the most intense gaming scenarios.

ROG Heatsinks. Let it sink in
The integrated ROG heatsinks have 2x more volume than traditional designs, resulting in significantly lower temperatures inside ROG Strix Series PSUs. This extends the lifespan of components and allows 0dB operation for a longer duration than standard designs. The heatsinks are so effective that fan noise stays whisper quiet, even under full load.

Dual Ball Fan Bearings. 2x longer lifespan
Different bearing types have unique pros and cons. In a PSU, durability is paramount, so we built a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.

0dB Technology Quiet. intelligence
An onboard controller brings the 135mm fan to a standstill when thermal design power (TDP) is below 40%, letting you enjoy light gaming in relative silence. Above 40% TDP, the fans automatically start up again.

80 Plus Gold Certification. Heart of gold
Top-end Japanese capacitors ensure efficient operation and have helped the Strix earn an 80 PLUS Gold certification. The increased efficiency also results in less heat, reducing noise and increasing reliability.
