But of course you always want to leave alot of room for upgrades and new builds en such...
ya thats true, but in this case i wont upgrade for a long time after i get two the HD 3870 x2's n Phenom 9900.

Apokalipse, the 520w from Corsair i chose before, says that it probably wouldnt be enough to power 4 GPUs: HD 3870 x2's in Crossfire but the GPUs r built on 55nm fabric processing, so the power consumption should be low but how low idk. How many watts it consumes we dont know yet but from seeing the HD 3870s consume way lower then the G92 at most times is unbelievable.

to end me making PSU question threads, which PSU do u recommend me getting?

There is no difference between a 1000 watt psu and a 500 watt psu on the power bill if you only use 400 watts. If a psu says it is a 1000 watts, that is what it does max. If you are only using 400 watts, then it puts out 400 watts, and that is what you will pay for on the power bill.

ATI recommends 75w power connector per card. So since you plan on running 2 cards, a safe bet would be to count on 150w for you 2 cards.

Avoid the xclio, when I was looking at PSUs I found several reviews that showed them being TERRIBLE on ripple tests.

Personally I have a Hiper and it works flawlessly and is very quiet.

Do not read Newegg reviews. People who write them are, for lack of a better word, retarded.

Xclio is fine... Sure there are better, but the brand is one of the best "Bang for your Buckers."

Dude.

Why not get the Corsair HX520W.....it's all you need.

Newegg.com - CORSAIR CMPSU-520HX ATX12V v2.2 and EPS12V 2.91 520W Power Supply 100 - 240 V UL, CUL, CE, CB, FCC Class B, TUV, CCC, C-tick - Retail

Well the point you are trying to make is correct, but that statement isn't quite true. You've forgotten about PSU efficiency. Currently, most high quality PSUs are about 85% efficient at best...which means 400 watts would really use 460w of power
