Asus B450 F 5800X 16 GB Corsair Vengeance RAM PC is not posting. Mobo shows a yellow light, there were storms and I was away, so I’m unsure what caused the power loss. Edit: The post indicates a yellow light. What part should I replace first? I took out the RAM and tested each stick separately, but it still won’t post. The Mobo also didn’t spin the fans when I pressed the power button until I cleared the TC jumper. Full disclosure, I didn’t test before touching the jumper and it was connected to main power. Now it won’t even start the boot cycle this morning. When I leave work, I’ll replace the spare PSU.
Could all components depend on the main power rail to function? I'm using a backup PSU to check the RAM.
The issue with surges is they can cause damage unpredictably. A single component might fail while another remains intact. One part could be damaged, yet another might survive. This is why people invest in quality power supplies and change them often. Such electrical incidents typically originate from the end of the line, but can start at either an outlet or a power supply unit. That’s why people take extreme measures to safeguard their wiring, even though lightning can easily pass through almost anything. A power supply might still function after such an event, but usually not. If it were a line-related problem, it would have handled other devices as well—like wall clocks without battery backups that might reset. It’s likely your surge protector has failed completely, leaving you with a simple extension cord. If it still works, it probably wasn’t affected by the surge.
Placed an order for a new motherboard and a PSU tester to ensure safety.
I don’t find much to be impressed by PSU testers. They look like multipoint meters with a green indicator for readings within 10% and a red one for those outside that range. They don’t give details on how close something is getting. When testing many units, it makes sense since they’re so much quicker.
