As far as PSUs are concerned, Antec, Enermax, OCZ, Coolermaster, and Hiper are some of the more well known and well regarded PSU makers. What you need to do is find a PSU that you think looks good, then google search for reviews of that SPECIFIC model since even different models made by the same manufacturer can vary greatly as far as quality and performance.
For the most part, one 8800GT is the same as the next because to date they are all based on Nvidia's reference designs. The specifications will show you what they are clocked at. What you want to be concerned with is manufacturer reputation and warranty. XFX for instance is a well-known card manufacturer that supports their product with a lifetime warranty. I believe BFG also provides a lifetime warranty on their cards.
Here are the 8800 GTS (G92) cards that Newegg currently has listed. You can tell by their core clocks whether they are overclocked or not. Once you find one, go to manufacturers product page and check on their warranty info.http://www.newegg.co...amp;srchInDesc=
Something like this PSU should be more than enough to suit your needs:http://www.newegg.co...N82E16817371001
