idles at 42 degrees and on full load it goes upto 60 degrees but when i was benching the card using furmark as soon as it hit 60 degrees it crashed happened thrice but i bumped up the fan to 60% it ran perfectly many times but iwas getting only 11-12fps when i was getting 32 before....and when i use amd overdrive the gpu clock always idles

after research... according to amacrox, your psu uses 4 separate rails, each rated at 18A. 12V1 cpu, 12V2 PCI-E, 12V3 mobo+acc, 12V4 PCI-E. Power requirements for your 7790 are 500w minimum psu, 21A on 12Vrail. Basically you are skirting the failsafe line on your gpu, and when you cross it.. blackscreen. I'd replace the psu with one with a higher grade. At the very least turn down the graphics, lower the draw on the psu for now before it crashes and stays crashed.

The 500w minimum stated is usually applied to single rail psu's which carry a much higher Amp rating on 1 rail vrs lower on multiple rails. Can be misleading.

Its my best guess. You look to be a victim of 'corporate slippery tongueage." They say its 550w, but only the fine print says just how much is on each rail. It also took me an hour to find the '21A', as each website I looked at only listed the 500w minimum. If your board had 2x6-pin connectors, you'd be just fine as the board would draw on 2 rails, at a lesser amperage, but you have 1x6-pin so are trying to pull at high load @20A and your rail is trying to give you the bird. I even thought of a reverse splitter to join the 2 xPCI-E into 1x6-pin but it seems no one makes one. Best thing to do for now would be to turn your resolution down, if you can lower the draw on that rail and not pull more than 16-17A, at most, you'll live to see tomorrow. If you keep snapping the over current protection and shutting the gpu down, sooner or later something else is gonna give and either your psu will be shot, or your gpu or possibly both.

Sorry, its the best I can do, but please try to get another opinion, while I don't believe I'm wrong about this, its possible.

Just as a side note, the XFX Pro 550w psu, built by Seasonic (The best, don't argue hah!) has 44A on a single rail, vrs the 18A on each of your 4. It'll power your system with more than enough room to spare. Its also currently on sale at newegg
