I had several random crashes with abrupt supply cut . This happened generally after i put my 2nd 1080p screen but not every times . Yesterday i had some hudge growing junction temperature to 110 °C in usual game ; the parameter i changed on adrenalin was HDCP set to off and another parameter set to off improving number of fps keeping a good quality .
Yesterday , the junction T° stayed high in game ,always growing despite computer restarts , cutting off suddenly the PC supply .
The supply cut could happpened before several times , even at cold , with wattman crash message after windows 10 return .
I think that all these problems has obviously a GPU card power management problem and with wattman .
So when i put on adrenalin : parameters -> settings -> GPU -> undervoltage , that always resolved my problems until now and yesterday .
My system : 7900 XTX , Windows 10 22H2 , latest gpu and X570 drivers desinstalled and installed after windows 10 were updated to 22H2 .
For dev : i have always the 1080p 2nd screen displayed in half vertical full horizontal if not 3D ( blurry ) mode is set on windows . Maybe the multi screen is an origin of wattman crash and supply cut .
