Yo!

Building a new system this week;

Asus GeForce GTX 560Ti DirectCU II 1024MB
Intel Core i5-2500K 3.30GHz (Sandybridge)
Asus P8P67 PRO Intel P67
Corsair Vengeance 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz

MISC:
4 fans/Antec Kúhler H2O 620 CPU Watercooler

I'm mixed on whether to purchase a 650W PSU or 750W, with 650W I can afford modular but with 750W I get Medusa's head :p (I'm looking at the Corsair/Antec PSU's).

So yeah, my question is do I really need a 750W PSU?

edit: I do see myself overclocking and in the future upgrading to more RAM.

650 will be fine with single card really. In fact, plenty. You wont pull more than 440W in extreme conditions. You could SLI 560ti with 650, but really 750W would be better for that purpose.

And don't look at CoolerMasters, but look at Antec, Corsair, Lepa and XFX. :)

Here's a compilation of PSU reviews and specs.
