can i run a ati radeon 5770 and quad core phenom 3.2ghz on a 500w peak psu atx, or will it over heat and burn out i am planning on getting this case for the computer - http://www.pbtech.co.nz/index.php?page=41&s=CoolerMaste...
if i need to get a better case please tell me , i would like to get a case with a psu for a price cut seince i have a $1,000 budget and i still need to find other parts. Or would getting a psu without the case and buying a 750w which would cost me a fair bit more and could make my other computer parts downgraded im not sure what to do. this is the one im thinking of getting Corsair 550W VX Series PSU Ultra-quiet 120mm double ball-bearing fan

What 500W PSU? I am running a 4850 and a PII 955 on an Antec EA500, you dont need more than a good 500 or 550W unit for it, but a crappy 500W unit will not suffice.

Well do get a decent 500W psu. After that, you just need a compatible case to fit it in, with all the other components.
In the specifications of the PSU, it should be mentioned "80+ certified", the current values on the +12 V rails should approximately add upto 40-45 A. This is for a 500W unit. If it satisfies all of this, it is decent enough.

A brand name 500W would suffice, but I would suggest getting something like the corsair 550W (or 520w modular) - they're reasonably priced, and quite reliable. 650W is overkill unless you plan on cf, and even then I would expect 5770 cards not to stress the 550w psu excessively.

It depends on the brand, the wattage on a PSU is not relevant as it varies a lot between manufacturers. What you want to do is, on sites like newegg, there is generally a picture of the sticker on the side of the PSU, if there isnt a picture of that sticker skip it and move on. You also want to make sure it doesnt have a little red voltage switch on the back(that indicates passive PFC) as that is an old design. You also want atleast a 5 year warranty on your PSU as it doesnt get outdated and a crappy PSU can potentially kill you whole system.

On that sticker you specifically want to look at the 12V rail, for a 500W PSU it should have ~40A on that rail. A nice 520W PSU is the new Seasonic S12II
