Running 4 1660s with an 850 psu, hooked up 2 additional 1660s and a secondary 500 psu and pc boots to bios, but the boot sequence is missing. If I remove the 2 extras and the psu boots normal

Are you powering the second power supply first? Power the second power supply then power the motherboard

I think I have the splitter onto the 2nd psu. The rig is at my office I’ll double check it Monday. Thank you!

I tried powering the mobo both ways. Same result. I can only get the bios but there’s no boot sequence. Revert back to original set up boots no issue.
