Highly doubt it. It has to be something with your voltage settings or power settings in your BIOS. The psu would be the last thing on my mind if I had an unstable overclock. I wouldn't know much about Furmark.

I'm 99.99999% sure it is the BIOS settings you have that is making your overclock unstable.

I have a haf x and a seasonic X-1050 and all the cables are long enough. Plus the PSU has two fan modes, Normal and hybrid. When hybrid is on the fan doesn't even spin when you are idle so the thing is dead quiet.

I honestly don't think it is the power supply that is causing problems with your overclock. And if you want to go SLI with the 560 Ti, a 850W power supply is enough.

For reference, my sig rig pulls 843W from the wall under max load (OCCT PSU test, basically a linpack + OCCT GPU test at the same time). Taking into account efficiency that's a system power draw of 733W. This is with an OC'd i7 930 + 2x OC'd GTX 570.

I am looking at this another way.Our OP wants to solve an unstable overclock with a power supply replacement.I suggest that issue come front and center.How would you like your new power supply to be multi gpu capable but still have an unstable overclock? Unstable overclock due to voltage flucuations,I would be testing with another power supply but getting ready for a motherboard replacement or accepting my cpu just is not going to go where i want it

The reason I think the PSU is the problem is because I'm watching the CPU voltage drop from 1.4v idle to 1.32v under load. The motherboard is a brand new ASUS Sabertooth 990FX. Several others have used my same setup to hit 4.4ghz stable using 1.4v for the CPU. If the PSU isn't the problem, then what is causing the voltage drop? See one of my previous posts for the voltages I'm seeing elsewhere.
