Psu issue. Help

[Mahbub]

Few days ago when my pc would be under load, the screen would go off and the GPU fans would start to spin at 100% and remain like that. The Pc would remain on but the screen showed no issue. I tested with another psu and it was fine. So i opened dusted and reassembled and it was running fine for 3 days today again same issue. Please help. 

 

i5 8600k, gtx1080, CM V750.

It's unlikely to be a PSU issue. Then the PSU would cut the power.

I have a second psu. But it was 8 plus 6 pin for gpu while mine uses two 8 pin. Is it safe to test gpu for some days with that? Its 600w

What model is it?

The 8 pin just has a ground and a Vsense wire over the 6 pin. Should be fine, if it powers on, and assuming the PSU isn't crap.
