Yep 750 should be fine, though i wouldnt want to do too much heavy overclocking

OMG!!

DON'T power it up because it will BLOW up and take HALF the CONTINENT with you!!1!

Yes my friend it is more then enough for you. I build about the same rig for my little brother with a i5 3570K and HD6950 OC and it runs on a (good quality) 650W Power Supply. The Difference between a 3570 and 3570K doesn't mean you go from SAFE to DANGEROUS, that alone will never make the difference on a power unit. By overclocking he means MANUALLY overclocking your CPU from the BIOS. Not the "K" version CPU. So you will be absolutely safe as you probably don't have the knowledge/need to overclock it anyway.

IT'S OK with 750W, no worries!
