So my PC stopped working this morning. The computer just shutdown suddenly on its own; at first I thought the power had gone out, but after checking inside my computer, I saw my motherboard power LED was off. I tried replugging my PSU but the mobo LED would not turn on nor would the computer start.
So I tested my PSU (Seasonic M12II 620 Bronze) with the paperclip test, and it failed. The fan doesn't start spinning at all. Then I retried the test after plugging in my case fans to give it some load. Still no luck.
Is it safe to assume that I have a faulty PSU? I've barely finished building this PC about 3 weeks ago and have been using it since then, but I didn't do anything different or out-of-the-ordinary with it this morning when it shut down. I have no idea why it suddenly shut down in the first place, either. Thanks for your time.
