Very nice PSU. I had a Nspire, still have it sitting in the closet were it belongs, that when ever I started playing a game or converting audio/video files the system would randomly shutdown. I thought it was my UPS causing it so disconnected but later that evening it did it. In short, replace the Nspire with the Corsair 750 and have not had one problem and here soon it is going to get it's workout when I get a 3870X2 from a friend and do some Quadfire!! Make sure you have a place to tuck some of the wires away if your about clean cabling cause the Corsair comes with ALOT. If you have any extra money to spend you could go with the 1000W Corsair which is modulated,
