Minimum requirements is 450W. Thats Cooler Master is one of there lowerend units. It really only has 324W and 27 amps. on the 12V rail. It should be ok, but if you start getting random shut downs or restarts, it will probably be the power supply.

ok thanx stranglehold. I forgot to mention i have a sapphire 4670 in my computer right now and it does fine, but then again, it only takes 59w and doesn't need an external power cord, gets it from the pci-e
