I have another problem with my 5700XT. I had the same problem with my old vega64
I have an inverter APC UPS pro 1500. (865W / 1500VA) and sometime, when i play on a game, i have peak to 1800W.
I found that bug with my inverter cause when it reach its maximum load, some fans starts.
My first vega64 burned up on his cable. So i bought another one and i decided to search why.
I downloaded some software (pict bellow) and looked why. And i found a 1800w consommation.
Its just a peak and i dont know why and how its possible.
It last bellow 0.5s but its able to damage your graphic card. (See the second pict)
Then i still have that problem with my 5700XT. Sometime i have a blackscreen and the AMD software crash or with an alert with AMD pop-up defaut power.
Please help me to clear those problems.
