So I was changing the case fans, after I put everything back together, I forgot to plug in the power for the GPU. I turned the pc on and I saw the white LED on GPU power port lid up and heard the fan spins like crazy (I don’t know if it was the CPU fan or the GPU fans), I panicked and immediately turned off the power supply.
Everything happened in less than 2 seconds, I’ve run some stress tests and gamed for a few hours and nothing bad happened (yet?) so I assumed everything is still fine (for now?).
What happens if I had left it on like that for longer? And why did the fan ram up like that?
Nothing happens, the GPU doesn’t turn on. You’re all good.
I can answer that because I’ve done this multiple times by accident… Nothing happens, don’t worry about it.
Barring rare circumstances from already marginal hardware nearing EOL, the worst thing that might happen is your OS install is bricked from cutting power while it starts booting.
It’s gonna be fine.
Modern computer parts are made with safety checks. If you dont have the power plugged it it will pause on the initialization page and state that you need to plug your GPU in. Remember doing this with a 660TI
“what happens when I don’t plug thing in?”
Thing does not work.
Next question.
The chances of something happening are almost zero. Modern hardware does self checks and us unlikely to blow itself up.
