Hello Everyone, I’m looking for some advice. I’m assembling a new computer to swap in with my old one. When I powered it up, the only thing that appeared to be working was my HDD, which I could confirm was spinning. I checked the power supply and saw the following display. I initially thought it might be my motherboard, but now I suspect it’s the PSU. This is the seventh PC I’ve constructed, and this is the first time it’s happened. Any suggestions on the specifications? I’m using a Ryzen 5800x, a new Gigabyte x570 with 32GB RAM (from the old machine), and a 1080 Ti Thermaltake Toughpower GF1 PE 850.

You likely have a manual that clarifies fault codes. The F in +12V rail indicates a specific issue—possibly a bad power supply unit or an overcurrent protection tripping. Spend time verifying all cables are properly connected and the insulation isn’t damaged, which could cause a short. A simple test involves swapping with another working PSU to see if the problem persists. An 850W unit should suffice for your system, but if it fails, you may need to return it or initiate a replacement process. Good luck!
