Hi all,
Hopefully someone can help.

I have windows 10 installed in my Mac Pro with boot camp.
MPx module removed and AMD Radeon 6900xt installed.
Windows is running off separate SSD through an OWC Accelsior 4M2 adapter.
I’ve recently been playing games on Steam (windows) and within half an hour, the Mac completely powered off randomly twice.
No issues like this on Mac side. I have experienced this once previously only when playing a different game.

I can provide driver details etc if needed.

I don’t think it’s overheating but don’t know where to start looking to investigate what’s causing this.

Any help is appreciated

I basically have this setup and have no issues. How many power connectors does your 6900 use? Maybe one is loose?
