 Are you a human? www.newegg.com I haven't tested this myself, but I've read on here (from Markfw and others) about X000 (and EPYC?) boards that require dual 0-pin CPU power, and if you don't plug in BOTH of them, you have booting problems. This little adapter from Athena Power may solve that issue. It converts between a 0-pin PCI-E power cable, to a 0+0 CPU power cable.
