Power problems!
Power problems!
I have a brand new machine with an RMA for the motherboard. It wouldn’t turn on with the CPU, even though it should. Once I got a new board, everything worked fine. My power supply also failed—once it powered on but then shut off completely. After waiting hours, overnight, and trying to reset it while unplugging the PSU, it came back on again. Now I’m thinking about replacing the power supply. I also had an RMA for a new Antec HCG 650W unit, but I ended up using an EVGA Supernova P6 power supply instead. It finally works! I’m relieved. Now I just need to install Windows 10 and everything seems okay. The specs are: CPU Ryzen 5600X, GPU MSI 3070 Ti Supreme, motherboard MSI B550 A Pro, power supply EVGA Supernova 1000W P6, RAM Ripjaws 2x8, storage Infinity NVMe 2TB.
Because it’s not clear this time. I’m confused and haven’t felt better since. Haha, I’m lying.

Honestly, it doesn't seem like a power problem at all—it might be hardware-related. You could try power cycling your motherboard if needed. Since it's hard to pinpoint the exact issue, just keep testing. Don't need all the RAM to start up, so boot with one stick and see if it works. If it doesn't, swap slots or RAMs, re-seat the CPU, and check connections. Make sure your cooler is applying even pressure and all connectors are firmly in place. Also verify the GPU's power connector is secure. Try booting with and without it to narrow down the cause.

Have you given any thought to a possible problem in the electrical circuit feeding the machine? It's not that common, but it happens. EDIT: Also a long shot, but there could be a screw or something hiding underneath the board shorting it out against the case, or even a flaky ATX power block on the board itself. What about the cord? Have you tried swapping it out?

Since the only concern was my power system not turning back on, I checked my PSU, unplugged it for a while, and then restarted it. After a short wait, I tried to power it back on again, but the issue repeated. The main difference between my setup and the others I mentioned is that with the Antec model, it would switch itself on and off automatically, while the Evga units stayed on until I checked the BIOS. When I stopped using my PC to prepare for a Windows installation, I found it still couldn’t power itself back on.

Sometimes it’s as basic as a damaged outlet or electrical interference, in which case you’ll need to replace it or use a line conditioner with a UPS. This isn’t a replacement for fixing the actual problem, just an added layer of safety.
