i am looking to get a new gpu today n need help when i built this i got a bigger PSU so that later on i figured i could handle most anything, my PSU is a Coolmax 700w Model# CU-700B, im looking at the 560 fermi since i cant afford the TI version and it would bottle neck me. please help let me no if my PSU can handle that GPU
CPU- AMD 965 BE at 4.0 GHZ
ram- 4gb ddr3 OC to 1600 mhz
mobo- MSI 870U G55
case- Antec 300
HDD- 640gb WD blue
GPU- Zotac 9600 GT
PSU- Coolmax 700w
That PSU is total crap, some users are saying it cant even handle 300W of load. You will need to upgrade to a quality (Antec, Corsair, OCZ, Seasonic and some others) 500W unit if you want to use a GTX 560. Also, an HD 6870 is also a great card, about as fast as the GTX 560, but cheaper.
Well here are some brands to consider. OCZ, Corsair, PC Power and Cooling, Antec, XFX and SeaSonic (in no specific order). You will only need 500w. If they have this one, I would get it (although I don't think they will). http://www.frys.com/product/6778855?site=sr:SEARCH:MAIN...
If they don't I would get one of the ones I previously mentioned, preferably the OCZ modular one.
last time i was there they had a bunch of coolermaster and some antec parts. just look for something in the $50-80 range with about 500-750 watts with a brand like antec, cosair, seasonic, xfx, and try for at least 80+ efficiency or 80+ bronze. typically those with those efficiency ratings are gonna be higher quality.
