I am buying a new Graphics Card that requires a 500w power supply. My current PSU is 480w. If I don't OC anything will the 480w be sufficient?

Here is the card:

If you know of a better or equivalent card that will run on my 480w PSU please let me know. If you know of a cheap PSU that I could buy (<$50) please let me know.

Thanks a lot!

What 480W PSU do you have? PSUs vary greatly in quality and the only 480W units i see on newegg terrify me.

If its a decent 480W unit the 5770 should run without an issue, if its one of the POS logisys units you need to swap it out.

Raidmax are infamous for going "boom" when you try to pull more than half of what they're rated for. Always go for Seasonic / Corsair / Antec / XFX units (and some others) that are rated good by places such as jonnyguru or hardwaresecrets.

That Corsair CX500 V2 is a good unit and will last you for quite a while and will power most single gpu cards today.

Never, ever buy a PSU that advertises its output in "peak power". Peak power ratings are meaningless.
