[Solved] X370 Killer SLI AC dead board?

[URL=][/URL]Just got my build put together and I can't get it to power on. I have tried everything mentioned in all other no post threads.

I have tested the PSU via paperclip and multimeter and it appears fine.

Weird thing is, it will power on if the cpu power is unplugged. Is it possible I got a bad processor? It's a ryzen 1500x

Just realized the bios is only v1.6 as listed on the sticker P1.6. So maybe it's not recognizing the cpu? Would that prevent me from powering on?

Gonna take it apart and bench test tomorrow.

No fans do not spin unless the cpu 4+4 power is left unplugged.

Or not.

Have you decided what you're going to do concerning that older BIOS?
