I really dont think that you can spend less than a hundred dollars on a power supply to supply that. And if your willing to spend so much on the computer parts, why dont you spend the same on the thing that powers them?


I agree. Considering you're putting together such a beefy system, it'll be worth your while to invest in a high power and good quality PSU. Im not sure of a model, but PSUs from Antec are really good. I suggest you get a 550 Watt PSU at the very least for your system...


I have a 550W Coolmax in my system. Very happy with it. It runs quiet and fairly cool, plus has a manual switch on the back to control fan speed. It replaced the giant (and very hot) Antec I once had. I'd recommend Coolmax. Mine cost around $80, and they make even higher-end power supplies than that.


Try this calculator:

It lets you work out what supply you will need quite easily.

As for buying a PSU i would look to spend as much money as you can afford, building an amazing system only to have it get fried by a $40 PSU is an experience we can all live without! :rolleyes:
