Disconnect the PSU from the regular motherboard.
You're facing an issue where the PSU fans spin but don't power on. It might be due to a protection feature in your motherboard that prevents powering up if the system isn't ready. Since you have four fans and none are working, it could indicate a faulty or incompatible setup. Check if the PSU is compatible with your ASUS board and consider bypassing the protection by resetting the BIOS or using a different power supply. If the problem persists, contact the seller for a replacement or verify the product details.
I'd guess it's because of your RAM mix-and-match rather than the power supply, or perhaps the lack of a CMOS battery. Ever booted this board with a different power supply?
It starts up properly using another power supply unit. I've tested various good motherboards, but the issue remains consistent. One RAM slot isn't working because of a bent pin, though I can't recall which one. I assembled a system with this setup and it failed to boot. I also used an EVGA 1000W PSU with the motherboard shown, and it worked fine.
It starts up properly with another PSU I own, but one RAM slot isn't working because a pin is bent. I've tried several good motherboards and none have the issue. I assembled a system with this setup and it failed to boot. An EVGA 1000W PSU also worked fine in the photo. It seems the hardware might not be compatible, especially since the original system used a Supermicro X11SCQ board. The connections could differ, and I can power on the PC by shorting the power switch, but it stays on that way after startup.
