I feel unclean by naming my thread this way.
My computer’s power button doesn’t respond. I unplugged the power switch cable and shorted those pins, but nothing happened. There’s a rainbow LED on the mobo that still cycles when the PSU is turned on, yet the system won’t start. I had a spare mobo with a built-in power button and CPU, so I connected my PSU to test, and it worked fine (even though it lacked cooling). I’m wondering if the issue lies with the mobo itself, given that shorting the pins didn’t help and the PSU still powers another board. Are there any steps I can take to further diagnose before replacing it?

Welcome to the forums, newcomer!
When sharing a troubleshooting thread, make sure to provide detailed information about your setup. List your specifications clearly, such as:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Also include the age of the PSU along with its make and model. BIOS version for your motherboard at this time.
Include all components used during your troubleshooting process. Check the sockets for any bent or damaged pins. Try booting the system on a breadboard to see if it powers up.

CPU: AMD Ryzen 9 7900X3D
Cooler: NEXT KRAKEN 240
Mobo: ASRock B650M Pro RS – BIOS version unknown and inoperable
RAM: GSKILL Trident Z5 2x16GB
SSD 1: Crucial MX300 1TB
SSD 2: OCZ Agility3 60GB
SSHD 3: Seagate ST4000DX001 4TB
HDD 4: Seagate IronWolf Pro 18TB
NVMe 5: TimeTec MS12 2TB
GPU 1: AMD Radeon RX 7700XT
GPU 2: NVidia Titan X
PSU: be quiet! Dark Power 13 850W – barely over six months old
Chassis: Some Dragon Rider chassis, acquired 15 years ago; no memory of model or source
OS: Arch Linux/Windows 10 dual boot (primarily Linux currently)
Monitor 1: Samsung UN58MU6100 (HDMI disabled on AMD card)
Monitor 2: ASUS MG28U (DP2 disabled on NVidia card)
Monitor 3: LG 29UM67-P (HDMI disabled on NVidia card)
These components are the usual setup. The test rig consisted only of PSU, motherboard, CPU, RAM, cooler, and necessary cables. Nothing functions – fans don’t move, no startup, no lights. It’s essentially a solid block, even when breadboarded.
When I verified the PSU (which it did), I used a separate motherboard (msi X99A Gaming Pro Carbon), CPU (Intel i7-6950X), and RAM (TimeTec 4x16GB). No cooler was present.
Edit: I installed a cooler in the test setup to verify power delivery on the PSU and to try the 7700XT, which I thought might be affected. PSU readings were normal, and the GPU worked. It appears the motherboard is faulty. If anyone has ideas before purchasing a new board tomorrow, it would be helpful.
