You guys make laugh everytime there is a question in regards to how much power is needed... you have no idea how powerful 850W really is. Even with 3 GTX260s a TX750W would be enough.

OP, a 650W is more than enough for your build. Headroom? For when - 1, 2 years? Then I'll advise you to choose the TX750W only because the price difference is small compared to a 650W. Heck, if you were willing to go for 850W, you should consider a modular 750W. I just bought a Silverstone ST75F last friday on special at NCIX (NCIX.com - Buy Silverstone Strider ST75F 750W ATX12V 24PIN Modular Power Supply W/120MM Fan Active PFC SLI Ready - ST75F In Canada. Technology&promoid=1145).

Default Re: PSU for i5 build

hellO!

I just bought a CM GX series 500 watt PSU for my c2d build which I ultimately plan to change to an i5 build w/ either a EVGA GTS 450 or a HD 6790... (depending on whether i wanna play Arkham city with physx or not :p )

Any suggestions if the GX 550 is gonna fold under the i5/GTS 450 combo? I originally went for the GX 750 but the unsatisfactory review on this site, as well the poor demo I got from it left me confused.

Of those 2 I would take the corsair. Your setup would run fine on 500w PSU, so the 650 still gives you headroom for a graphics card upgrade. I would say unless you plan to go to a high end SLI setup in the next little while a 650-750 is more than enough. I would not go for the thermaltake.

I highly recommend that you do not buy thermaltake or coolermaster powersupply! As I have experience them sparking and taking a few hardware with it. My house has this bad habit of fluctuating electricity. So when I went with a Seasonic and Corsair power supply no problems ever since. Any quality power supply (although quality ain't cheap)should have no problems at all as a long as it is withing you specs. If you were to to expand to the near future as the above statements said I second 750watts, is more than enough for your build.
