Corsair AXi Digital ATX Series Power Supply
There are some great features in this series of gaming PSUs, but there are also some things that detract from them for overall value. In terms of power efficiency, you're not going to find many better options out there than these offerings from Corsair. The 760W, 860W, and 1200W models are all 80 PLUS Platinum rated, while the 1500W PSU is Titanium rated for near perfect power efficiency. All of these are also fully modular which means you can disconnect every single cable from them and only use those cords you need in your system. While semi-modular designs are good, it's pretty hard to beat full modular for ideal customization and internal clutter reduction. These PSUs utilize a single-rail design which would have been an issue in the past, but modern standards make single-rail PSUs ideal for serious gaming. Corsair offers a seven year warranty on this series.
