Just ordered a 950W Corsair for my new high end system.
Antec CP-850. Great PSU very happy with it
I've used a Corsair TX650W in my first two builds and I couldn't be happier. One is powering a Phenom II 710 with a HD4770 (over kill, I know) and the other is powering a Phenom II 945 and GTX 260.
I've got you all beat... 220 watt PSU in my one home-built HTPC.
I use a 750W Corsair. Corsair is my number 1, but a recent SSD experience left a sour taste in my mouth... Anyone with a Force SSD knows what I mean probably.
Other than that, I stick to Seasonic, PC Power/Cooling, Antec, and XFX (rebranded PC Power/Cooling).
My PSU fought Chuck Norris to a draw, is that powerful enough?
I have a 1000W PSU that came with my CM Stacker 830.
My power supplyes it Antec CP 850W
I also have a 1KW PSU that came with my Stacker 830 Evo
Cooler Master Silent Pro 1000w with a single 80A 12v rail.
