ASUS ROG Strix 850W Gold Aura Edition (Fully Modular Power Supply, 80+ Gold Certified, ATX 3.0 Compatible, PCIe Gen 5.0 Ready, Dual Ball Bearing, Axial-tech Fan, Aura Sync, 10 Year Warranty)

The ROG Strix 850W Gold Aura Edition is encased in a strong, sleek aluminum chassis that also acts as a heatsink for the internal power transformer, further helping to reduce temperatures and minimize noise.
ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.
Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. For ROG Strix Aura Edition PSUs, we've scaled that design to 135mm so it keeps things cool at low RPMs while producing less noise.
The fan impeller spins on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.
To reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is 60% or below.
