| Hello! I have just built a new PC with a B650 Steel Legend WiFi and AMD Ryzen 5 8500G that is failing to POST. When connected to power the LED under the lower M.2 slots lights up, so there's definitely power to the motherboard. It just doesn't react at all when the power button is pressed or the power terminals are jumpered. I have troubleshooted so far by disconnecting all connections from the motherboard except power, reinstalled the CPU, tried the RAM in all four slots, reset the CMOS. Any advice would be quite appreciated! |

Make sure you have the correct 8pin power cable connected to the board. If you have a 6+2 (PCIe power) cable connected the board's power safeties will kick in and prevent the system from powering up. You need an 8pin 4+4 (CPU power) connector. -------------
