I was setting up a hard drive into my PC while formatting it, trying to close the side panel for cables. After moving slightly, the screen went dark. I shut it down by pressing the power button, but it didn’t respond. I turned it off using the PSU switch, though the PSU LEDs stopped working. The PC still powers on, and the GPU and PSU lights should be visible. Specs include a Palit RTX 3060 Ti, Ryzen 5 1600, HyperX Fury 2x8GB 3200MHz, Gigabyte B450M DS3H V2, and an off-brand PSU. What should I do next?
Your inexpensive PSU might have blown, which is why you shouldn't tamper with anything inside the case while the system is running. You should swap out the entire PSU and be sure nothing else was damaged. Invest in a reliable, high-quality PSU—it's one of the most important parts you should never cut corners on.
This power supply is quite unreliable based on the reviews I’ve seen. It’s likely worth replacing it soon to avoid more damage. There are better options available if you’re looking for something more dependable.
