UPDATE: I fixed it!! It was the PSU.

So I just built my first PC in like 20 years. Everything was going fine, I was installing Windows and got to the network setup step and my wifi was having trouble staying connected. I figured it was because I hadn’t set up drivers yet, so I thought whatever, no problem, I’ll just move it by my router and plug in an ethernet cable.

So I powered off and moved it, and…dead. Nothing is happening when I hit the power button. No fans, no lights, nothing. I’ve made sure no cables got jiggled loose or anything. Maybe I shorted something somewhere on the motherboard? I can’t see anything without fully disassembling and having to rebuild it. I really don’t want to do that, but I guess I’ll have to unless I’m missing something obvious. I’ll test the PSU tomorrow but I doubt it’s that, these are all brand new parts.

Any ideas?

Specs:

AMD 7800X3D

ASRock B650E PG Riptide WiFi

Sapphire Nitro+ Radeon RX 7800 XT

2 x 16GB Crucial DDR5 RAM

Seasonic GX-850 PSU

    I didn’t :(

    I admittedly haven’t had much time to mess with it, but I confirmed the PSU is working, so I suspect the motherboard is fried. Still need to confirm that before I order a new one, and figure out why it happened so I don’t do that again. I’m hoping my CPU is still fine.

    I really appreciate everyone’s suggestions, helped me narrow it down a bit

      Just because the PSU works on another system (or God forbid, those awful “testers”) doesn’t mean that it’s fine. PSUs tend to fail in weird, unpredictable ways

        You were correct. PSUs be weird.

        I purposely went with Seasonic because I did not want to run into power supply issues, but here we are.

        Got a new one and am up and running
