750TX was tested and can exceed that 750 watt labelled max (can go to 900 watt)

So you should be fine.

It makes me laugh.

That 570 is shorter, yet whips both of those 260's in SLI. Has DX11, runs cooler, quieter. For F2H, dual cards will pull more PPD though. I love technology.

Actually, after crunching for several hours, the 570 is at 90C and the 260s are holding around 82-83C

The 260 doesn't use as much as they say it does. With both 260s and CPU at load it was just right around 400 watts. Plus, one of them is in a PCIe Gen 2 x4 slot, so perhaps it consumes less power. Either way, PSU is still going strong! I have a CM Real Power 650 that I was tempted to put the 260s on. lol

I was gonna say, the 570 is sucking air straight off the back of it's neighbor And those 260's have dipped intake's that are sucking air off of the end of the PCB, not where the chip is. Pretty good temps anyways!

Actually, without the fans blowing directly onto the GPUs, the 570 was up to 100C. It's actually at 90C when it's the only video card in the case. I think it likes to stay at 90C. It must be its favorite temp.
