The GPU is factory overclocked to 900 MHz. I also plan on overclocking the 2500k to something between 4.4 to 4.8 GHz. I was thinking about getting the CORSAIR Enthusiast Series TX750 V2 750W but this is my first build so I'd like to ask some people with experience about this. I'm also wondering if this PSU would be sufficient for SLi. I'm not sure if I want to do SLI at all though since I have to upgrade the motherboard. Thanks in advance.

With the i5 at stock you're looking at under 400 watts, and even overclocked well under 500.

i7 - 2600k @ 4.0, under 360 watts:

This i7-920 at 3.6 with _2_ 560ti overclocked is only using 628 watts:

So yes, the 750 is fine for SLI of the 560's

i had a tx750 running a 920 at 4GHz and 2x 5850s at 5870 speeds. i think you should be fine.
