SinTek 600SLI 600W PSU
 

It all comes down to performance, if you have gone out and spent a
boatload of cash on your mobo, CPU, ram and video card you are obviously
looking for performance so why would you put a budget PSU in a performance
rig? If you're a performance enthusiast and only the best will do, you
should definitely take a look at SinTek.
