Hello,
I recently received a new motherboard, CPU, RAM, and SSD. I reused my PSU and GPU, and installed it into a testbench from the previous case. I've assembled PCs before, but this issue has never occurred to me. After setting everything up and connecting everything, I turned on the PSU. Pressing the switch at the back didn't power anything—no PSU fan, no CPU fan, no lights—but the keyboard connected to an I/O USB and lit up. I assumed the PSU wasn't receiving power, but the keyboard lights worked. I checked the CMOS reset stick, removed RAM and GPU, and even unplugged everything except the PSU, yet nothing turned on except the keyboard lights. Any advice?
Sorry, I didn't include that detail. I also just attempted to jump it as you suggested.
Did you exclusively utilize cables from the Seasonic PSU, and are there no cables from other PSUs?
That's correct. It's a semi-modular setup, and I only connected one modular cable this time, such as the SATA power for my SSD.
Verify that both the 8-pin and 24-pin power cords are securely connected to the motherboard. Since your CPU does not include built-in video, you need a GPU installed.
