I have a 1200W power supply, Sparkle (SPI) Magna Pro Gold. Single rail, 8 pci-e, 80plus gold, and modular. Check my thread here
https://bitcointalk.org/index.php?topic=219185.0 . Asking only $155 + ship. It's definately not a coolmax piece of crap since I ran 8 5k series radeon gpus on this without breaking a sweat, I'm selling though because I need a little more power because I'm moving to 7k series gpu's.
