Hi yesterday i was playing games when suddenly my PC turned off like on power blackout,it turned on about 5 sec after and my monitor didnt have any signal from GPU since then, when I looked in case my gpu wasnt on fans was off too only led was on ...I read on web that my PSU zalman 600 lx have short circuit protection so i am wondering if it is caused bcs my PSU had scircuit on that line and not delivering enough energy.Can it be done by this or is my GPU circuited out of nowhere???

We don't even know if the GPU is dead yet. Which is why we test with known good parts. *If* the GPU is dead, the first suspect would be the fairly low-quality power supply.

It's a very low-quality PSU, which I'd replace immediately. Whether the PSU is failing or the GPU is dying likely means you need to be able to test with known good parts, either a quality PSU in your rig or your GPU in another one. I'd replace the PSU under any circumstances, so the former is the better option.

Provide us with full hardware information.
It could happened by GPU itself, short power from PSU or even a faulty motherboard.
You can test stability of your PSU by connecting it to a working rig and using OCCT program,
it allows you to put your PC under heavy load and display temp/voltage graph.
