Default new psu

I just bought all the parts for my first build then found out the powersupply wasn't good. So I got a store credit and I was wondering what the best psu tigerdirect has under 50$ with atleast 550 watts.
Thank you

Why 550W, what are your computer specs?

Think this is about the best deal I can find. That is a good brand.

Corsair CMPSU-500CXV2 Builder Seriesô CX500 Power Supply - 500W, 80 Plus, 120mm Fan, Single +12V Rail, Active PFC at TigerDirect.com

Amd fx 4100
ASus m5a88-m mobo
Xfx radeon hd 5570
8 gigs of corsair vengeance
Cooler master hyper n520
Haf 912 case
4 hard drives a DVD drive and a fan controller.
I did some calculator thing and it said I needed a minimum of 550 watts so that's what I want.

Well, the 5570 requires at least a 400W. The FX uses only 95W. So technically, as long as it won't be on load 24/7, a 500W should be fine, IMO. Anyone agree?

So in your opinion should I get the 500w or get a slightly cheaper 550 or 600?

550W doesnt surprise me. It'd be a good psu size with a bit of overhead. That said, I think ati says 450W with that gpu.

Its unfortunate you only want tiger as they dont have great selectionsd.

However, the cx500 is the best/inexpensive option, but its oly under 50 if you count the mir.

edit

If you look at a 500 zand a 550 of the same price, yo'll see the Amps on the 12V are the same. Basically they both put out the same power.

i'd suggest bumping your budget $15 and getting a better 500W.
