I just completed my latest setup but it’s not displaying. After trying to power it up, nothing happens—no LEDs lighting up, no fans spinning, and only the Mobo RGB near the back IMO activates when the power supply is switched on, not when I turn the PC on. It seems the RGB stays on even when the system is off. I’ve updated the BIOS with a 32GB USB drive, followed ASUS’s instructions and some YouTube guides carefully. However, the BIOS USB header always shows a steady green light (no flashes, just consistent brightness). I’m not entirely confident about the connection method; even after reading the MMO manual for an hour, it still doesn’t clear up why no LEDs appear when I try to power the machine. It looks like there might be an issue with how the power switch is wired, possibly due to compatibility problems between the new Corsair RAM and the motherboard. The specs I have are: B550-F gaming (no WiFi), Ryzen 5600X, Corsair Vengeance 2x16GB at 3600MHz CL18 Pro SL RGB (recently released), Corsair RM650i, and a Gigabyte 1060 with a 6GB GPU (previously worked great). I also have a Samsung 970 EVO 500GB, Samsung 860 EVO 500GB, Seagate Barracuda 2TB with a 7200 RPM fan (120 PWM/RGB) plus three Phanteks 220 PWM/RGB fans.

Just to confirm, remove it and attempt the BIOS update. If you provide the motherboard details, we can assist more effectively regarding that front panel connection.

Check all power connectors carefully. The 24-pin connector is connected to the motherboard, and an 8-pin plug is on the top left for the CPU power. This board includes debug LEDs. Are any of them illuminated? While inspecting, confirm your RAM is set to B2 and A2. Spoiler: it should be.
