In this review we are taking a detailed look at one of Corsair’s new power supplies the AX850 Titanium. The AX Titanium series currently includes two models, the AX850 (850W) and the AX1000 (1,000W). Both power supplies comply with the highest standards for efficiency (80 Plus Titanium certification) and feature all modular cables and quiet operation. Note: not to be confused with the AX Platinum Series (760W and 860W) or the AXi Digital Series (1600W, 1500W, 1200W and 860W).

Along with the power supply Corsair includes three different colored labels that can be applied to the side of the unit to help color coordinate your next build if you so desire. The AX Titanium Series power supplies incorporate Corsair’s Zero RPM Fan Mode, which means the fan does not start spinning until the power supply reaches a moderate load (40%).
The Corsair AX Titanium Series is built with high-quality components, including all Japanese made electrolytic 105°C capacitors and a 135mm Fluid Dynamic Bearing (FDB) fan. Corsair guarantees these PSUs to deliver clean, stable, continuous power, at ambient temperatures up to 50°C and the AX Titanium power supplies come backed by no less than a 10-year warranty.
