Actually 550w can typically handle two 5850's quite easily.

I'll just leave this here:

5850~4870 and Q9550~x2@4ghz - power consumption wise.

ummm no joke, at full loud my system makes my PSU whine, maybe it is supposed to also pump out some major heat when it is folding too.

or maybe it is the CPU?

maybe the whine is from the gpu's instead of psu...and psu whine is quite normal too if its not too loud......

A pair of stock 5850s need 280W from the PSU at most. A SeaSonic M12 can deliver 456W of 12V power. Given the rest of your system, you'll be perfectly fine.

Either your problem is unrelated to power or you have a faulty unit. It's impossible for your rig to draw anywhere near 750w. The whine does not necessarily mean that your PSU is under stress or near its limits, either.
