I'm about to get another GTX 660 Ti for an SLi set-up. I already have the MSI N660 Ti PE/OC and i'm buying another Gigabyte GV-N66TOC-2GD (that's fine by the way, right?).

My question though is, will my PSU be good enough to handle this new setup? I'm not planning to buy a new PSU at all. If it'll be good enough and won't harm or 'downgrade 'my system it's fine for me.

I got a Coolermaster Silent Pro M2 620W. Please do some research on this PSU. It is Bronze PLUS certificated.

All system specs:
i5 4670k (overclocked to 4,3 GHz)
2x 660 Ti
MSI Z87 G45 Gaming
Samsung 1 TB HDD
Samsung 840 EVO 256 GB SSD
2x4 GB corsair vengeance LP
2x 120 mm fans, 1x 140 mm fan

I disagree. I think that PSU is fine for a 660 Ti SLI; they aren't very power-hungry cards. He won't have that much headroom for overclocking the GPUs, but it's not like he's butting up against the output capacity of the PSU.

An 800W setup could handle two 780s in SLI - it's clearly too much.

ok 800w is too high, but 620w psu will maybe only just manage 2 660ti in sli, its better to be safe than sorry
