ASUS ROG STRIX 850W 80 Plus Gold SMPS

The ASUS ROG Strix 850G is an 850-watt fully modular ATX power supply built for demanding gaming rigs that require reliable, efficient, and quiet power delivery. Carrying an 80 Plus Gold certification — achieved in part through premium Japanese capacitors and low RDS MOSFETs — the unit maintains high efficiency across a wide load range, reducing heat build-up and extending component longevity. Cooling on the ROG Strix 850G draws directly from technology developed for ASUS ROG graphics cards. The Axial-tech fan design uses a smaller hub to enable longer fan blades, paired with a barrier ring that channels airflow more effectively downward. This allows the 135 mm fan to maintain adequate cooling at lower RPMs, keeping noise levels minimal even under sustained loads. ROG heatsinks with approximately double the volume of conventional designs further help pull heat away from critical internal components, enabling prolonged 0dB operation. The 0dB Technology feature uses an onboard controller to bring the fan to a complete stop when total draw power falls below 40% of rated capacity, making the PSU completely silent during light gaming or everyday desktop tasks. Once load climbs above 40%, the fan resumes automatically. Dual ball fan bearings replace the more common sleeve bearing design, offering up to twice the operational lifespan — a meaningful advantage in a component that is expected to run continuously for years. The fully modular cable system eliminates unused cables from your chassis, improving airflow and tidying cable management. Included cables feature embedded capacitors to reduce voltage ripple. A magnetic ROG logo and included stickers allow visual customisation of the unit's visible side without permanent modification. ASUS backs the ROG Strix 850G with a 10-year warranty, reflecting confidence in its build quality.
