The Thermaltake Toughpower XT 775W PSU is a decent piece of kit for a mid-range enthusiast PC.  This PSU comes equipped with one large 64A +12v rail and supports 4 PCIe devices - 2x 6-pin and 2x 8-pin.  It is mostly modular and features a nice large fan that provides very good cooling to this unit under normal circumstances. . .
