They finally did it. Corsair finally moved their Power Supply lineup so far ahead of the game they have forced the scales we use to measure them with to change. Originally included in the 80 PLUS rating system, the Titanium rating was only included to cover future advancements down the line. The new Corsair AX1500i has reached that line, so we going to need more valuable precious metals for the system now.

Corsair’s new AX1500i was originally going to be a power update to the fan favorite AX1200i. Corsair has never been one to just meet a consumer demand, so they took the fully digital PSU to 1500 watts for quad SLI systems, but also bumped up the power efficiency to the Titanium level. This is quite a feat, since this requires an additional spec to pass as the unit has to deliver at least 90% at 10% load.

The Corsair AX1500i is not only a 1500 Watt PSU, fully digital, and holding the championship belt for power efficiency (94% efficiency at 50% load), but it is available right now for $449.99. While that is a lot to spend on a PSU, it will save you money on your power bill and comes with a 7 year warranty to ease your mind. You just got an instinct to reach for your wallet. Go with that instinct. More details below.
