I bought this PC 2 months ago. Yesterday, I had to transport it by car. Even though I packed it in the original box with foam, when I tried to set it up again, I noticed that this cable, which I had secured with electrical tape, was loose. I'm sure it wasn't loose before.
I know it's some kind of power cable, but I don't know where to plug it in (I'm not a hardware guy).
Note: The PC is turning on and functioning normally. I don't know if it's related or just a coincidence, but my headphones that I usually connect to the back stopped working.
Can someone shed some light on this?
Looks like a B550 series board which means those two headers on the motherboard would be chassis fan 1 and aio pump. If you look closely on the motherboard it should be labeled near the header (in the pic you can just barely read "ch" on the left side and "aio pump" on the right.) The cable looks like a molex to 3 or 4 pin power adapter which would've been used with an older chassis fan with a molex connector. If everything is already hooked up you can remove that adapter.
Edit: you can also look up your specific motherboard model and download the user manual which will give you a detailed layout of all of the headers on the board.
For OP:
Header = those silver things that stick straight out and there are several groups of them across the board. Usually they have small text beside them somewhere. Usually fans are labeled something like cha_fa0 or something.
It really has a label CHA_FAN1. Since all other fans are working I will assume this cable was stuck somewhere.
Thank you.
Thank you very much for the explanation. I will get the manual. It is an ASUSTeK COMPUTER INC. ROG STRIX B460-H GAMING (LGA1200).
