I was swapping out 750w PSU to 850w and connected both 8-pin and 4-pin CPU connectors and my mobo did not want to power up.
Nothing at all, completely dead. I did not have the 4-pin connected before so I guess that's why I never encountered this issue.
If I disconnect the 4-pin, the mobo is still dead.
If I disconnect everything (even the motherboard cable) and connect everything except the 4-pin, it works normally.
I tried both 750w and 850w and neither want to start the motherboard with the 4-pin connected.
The motherboard in question is MSI MPG Z390m Gaming Edge AC. The CPU I'm using is 9900k oced to 5ghz.
Now, everything works fine without the 4-pin, but I'm still curious why this is happening. Is it on its deathbed? Or perhaps not stable enough considering it's mATX?
