I had to swap out the power supply after the second SATA connector caught fire and damaged my hard drive. It hasn’t worked well since it disappeared from the system file manager. I replaced it with an older model, but it only provides 430W instead of the 500W I used before. Connecting the computer to a monitor gave no output. The original PSU was an EVGA 500W (80+) and the new one is a Corsair CX-430 (80+ Bronze). I currently have just my M.2 Samsung Evo 970 (boot drive) installed. I’ve tried connecting both the NVIDIA 3060 and the AMD integrated graphics, but neither works.

Did you verify the connections for a modular PSU? It’s possible the 430W unit has worn out and stopped working. When it attempts to start, does it display any error codes or sounds? Does it power down smoothly or abruptly? Are there any indicators on your keyboard or controller showing status?

Neither unit is designed to be modular. When powered on, all RGB components and fans activate, and the debug lights remain off.

Interesting.... other specs? And how long are you waiting? Could be memory training.

I checked Reddit, and the problem was resolved by switching the power supply to 650W and resetting the CMOs. Here’s the link to the discussion:
