Build: MB: Gigabyte z790 UD AC
CPU: 13600k
GPU: 4070 (msi)
PSU: corsair 750rx
Ram: CORSAIR VENGEANCE RGB DDR5 RAM 32GB 2x 16
Case: Lian Li 216 RBG
CPU cooler: Silent Assassin 120
Issue #0: My z790 UD AC when booted in QFLASH powers on Orange
Issue #1: I am unable to connect the front panel power in any configuration to get it to turn on. The front panel power mentioned in #11 on the first link does not work.
Issue #2: When using the provided QFlash on the z790, the machine powers on all fans, but it shuts down immediately once the RAM is detected, assuming the CPU receives power. This problem happens with both single and dual channel RAM.
I have confirmed that the MOBO and CPU power sections on the board are properly connected and show power as expected. There is some power reaching the case.
The main concern remains the front panel power switch not activating. Please let me know if any actions are needed to resolve this issue.
Attempt to energize your PC using a screwdriver. If successful, it may indicate the power button on your case is defective or the connecting wires are damaged. Consult page 26 of your manual for guidance.
Remove the 4070 from the motherboard and link your display directly to the correct connector. Also, test with one RAM stick.
Do you have any news? I encountered a similar problem with the Gigabyte Z690 board.
