Corsair is best known for its memory products-DIMMs and flash-but it has a solid line of power supply units, as well. The company sent ThinkComputers its TX750, a 750W unit with a single 60A 12V rail-powerful enough for a GeForce 8800 GTX. While non-modular, the cables are sleeved and have quick-release connectors. We tested this device with a five-year warranty-results within.
