I wonder if it's a coil wine. I'd try RMAing the Corsair.
Why are you buying 750-850W PSUs when your power draw is less then half that?
Rookie Mistake:
I wanted a PSU that would withstand future updates/builds, namely an additional gpu on SLI. But I have learned that it is better to buy a PSU with a proper wattage (in this case: less watts) in a higher end range.
Hi - The PSU will pull only the power from the wall that your components require regardless of wattage. So, a larger capacity PSU will do no harm except for your wallet because higher up front cost. If your are reasonably sure you are going to SLI the 660 then go ahead n get a good quality 750.
You are correct that you are much better off (reggardless of total power) getting a better quality PSU, such as enthusiast or professional level, than the budget level or off brands.You get better internal components and a longer warranty as well.
BTW, coil whine can also occur in higher quality PSU's, just not as frequently as lower quality units.
