what do you mean using 2 psu?
full system spec? include brand and model of the psu

try test with just 1 good psu?

I need 600+w for that gpu so i use 2 i mean i got both under 25 total euros 600w psu here cheapest one around 55e

so what I understood is that you are using one PSU for powering GPU and other to power your whole remaining system components. wow seriously.
I think this is because of irregular power or variated voltages.
I will recommend first to use one good GPU and test with it.

If GPU was working fine before then test with single RAM.

Does your GPU PSU have the correct PCIe cables for that PSU or are you using some kind of adapter?

if you're using 2 different cheap PSUs it's quite likely that that's your issue

Furmark is brutal on a gpu. Look it up anywhere, it's known as a gpu killer, literally. It's that brutal. Shutdowns with its use isn't unheard of.

I'd suggest using other software, such as MSI Kombuster, if trying to test the gpu. If you get the same results, it'd definitely point towards a hardware issue possibly a psu issue.
