I've got a Corsair TX750v1 in my computer right now. While the V1 is terrible in comparison to the V2 because of the group they worked with, it is still a very good PSU. The RM series from Corsair is about the best you're going to get right now too when it comes to quietness and correct power usage, whereas if you get a good HX model, like the 1050 or the old 850, you'd be gold also.
