Best power supply for 450 watt gpu?

Question

Hi, i'm getting a 450 watt gpu (gtx 660) and I need a power supply for it, Im looking for a cheap power supply, but will do the job efficiently.

Any ideas?

(If i get a psu matching the wattage for the gpu, then the pc won't work.)

Answer 1

600W Min.

Answer 2

Corsair CX450M is very good and cheap.

Answer 3

600W Min.

Answer 4

best to use a psu sizer app online to determine proper psu size. i use the one on the power supplies page at newegg.com. you have to know your cpu, mobo, etc. to get useful results [they use power, too].

note: overclocking eats power like crazy. an extra 100w just for the cpu isn't out of the question and overclocking the gpu also eats power ... and that's not included in the recommended size.
