Issue after upgrading CPU and flashing bios (lemmy.world)

BIOS version: 6332

Motherboard:

CPU:

According to part picker the cpu should work with version 5862

So it seats nicely and machine powers on, but then the lights on my mouse/keyboard flash on, then off. Then after about a minute the PC turns off.

According to part picker my power supply can handle what I have attached with the new CPU, but I don't really know how to test that.

Already took out the cmos battery and reset.

Putting in my old cpu works just fine, so I didn't brick anything.

Any ideas?

Put the new CPU in and clear the cmos (turn off PSU and bios battery for at least a few minutes) and try again. 5000 series should be the least picky with memory, but you never know what bios setting/memory setting could be making the CPU angry.

I'm annoyed that worked.

I had already reset the CMOS, but this time after installing it with the PSU off and battery out I went and had dinner.

I am now fully upgraded and running!

Are you using the additional AVX12V 4pin power in the upper left?
I would bet the 5950x needs the extra power. The old CPU may not.
