rx480 blackscreen help?

[Troy313]

I have had an rx480 for nearly a year now and it recently devolved an issue with what im assuming is state 0 (not fully sure) the only thing i know is it causes constant black screens and artifacts when im on the desktop with NO gpu load.. Sure there are simple fixed like add unigine heaven to start  with the pc Lmao... Ive tried increasing the power limit voltage and even tried down clocking nothing fixes the issues unless i have some sort of a game/load on the gpu and i cant RMA it so thats out of the question. Other things i have attempted is New windows install  New driver install via ddu Older driver install ect Please help thank you

Do you have a spare PSU to try it out with? this unit is quite bad and the FX8350 is a power sucker.

I dont wanna be mean but  its Fully stable under load.... i only have issues when its at idle

Wich is when there are the most power peaks from the components, peaks fo 200W or more aren't that uncommon.

And that could be the problem that the PSU isn't good enough to keep the voltage stable in this situations, wich causes the proble

 

It is a false assumption, that PSU problems only have to apply under (heavy) load. 

 

@Princess Cadence

Could you pls stop the FUD?!
FX8350 is equal to i7-3820 in power consumption, not any difference at all.

What really is a power sucker is Skylake-X wich can easily pull 400W through the CPU alone. 

The AMD FX aren't nearly as bad as that CPU is.

Bought new psu and now it seems more unstable with more frequent black screens and New strange artifacts appearing Rip gpu 2016-2017 my old 760 is Fully stable looks like im down grading back to old reliable
