I am attempting to use two identical 520w power supplies to run my gaming rig. I KNOW this is not recommended and I am only doing it temporarily while I wait for a PSU replacement. I am working on a portfolio for 3D animation which is due in 1 month so I absolutely need my computer running now. I have one PSU connected to my MOBO, CPU, fans and one graphics card and the second is shorted with a paper clip and connected to the other graphics card . When I had a single 1000w PSU I was running the graphics cards with SLI and I want to know if I can still do that even though each card is on a separate power supply.

Can I use SLI if I am running my graphics cards on separate power supplies?

I'm sure you can as long as you have it so the second PSU turns on with the main PSU otherwise that card won't get any power! If it doesn't then I recommend to buy some sort of PSU tester as it will boot the PSU as soon as you plug it into it.
So something like this:

Hopefully this helps and any others that know about PSUs or Graphics Cards then please feel free to correct me!

Thanks, I went ahead and turned it on (first the psu running just the graphics card, then the one running the system+everything else) and everything seems to be working fine! Since I'm seeing both graphics cards in my hardware monitor and SLI doesn't affect the power I'm guessing it's okay.
