How much power do I need for Phenom 955 & 460 gtx?

[ahsomsid]

Hi, I plan to build my own computer and I was wondering how much power my system would need. I plan to get

cpu: AMD phenom II X4 955
gpu: evga 460gtx
ram: gskill 4gb 1333
mobo: ASUS M4A88TD-V EVO
hdd: wd caviar black 500gb 7200rpm
odd: just a regular dvd writer
case: antec three hundred mid tower case

I was planning to get antec 620w but the rebate just ended and now it seems kind of pricey, so I wanted to get a 600w or even a 550w if my system isn't very power hungry. Would that be enough power for everything? I heard that having a good psu is pretty important, so I'm not sure if I can get a weaker psu's without killing my system :/ Oh and I'm probably not going to be overclocking anything... i might try overclocking my gpu.... but it's unlikely. Thanks!

You should run fine on a good 550-600W made by Corsair or Antec (if you get the right PSU). The GTX 460 is what is going to draw most of the power.

It says "Antec BP550 Plus 550W Continuous Power ATX12V V2.2 80 PLUS Certified Modular Active PFC Power Supply"
Does this sound good?

The BP 550 is alright, its not on my favorities or my crap list, but for only $5 more you can pick up the Seasonic S12II 520 which has 480W(40A) available between its 12V rails vs the BP 550s 384W(32A) which would be a bit closer to what i expect for a 450W unit. The S12II is also more efficient and uses better quality components, its not designed to be the bare minimum safe but still on a budget.

That PSU will work out just fine with that setup.
