What is This Cable? (Psu)

[sketchyfresh]

Hi guys, I’m super new to custom pc’s and so I have my case open and I’m looking at this 4 pin cable with a whole bunch of other connectors on it. It comes from my psu. Basically I bought a used pc from a guy and the intake fan is not set up. Unfortunately my mobo only supports 1 case fan so I want to connect a 2nd fan to the psu. Because this guy literally only has 1 cpu fan and 1 exhaust fan. So I’m just wondering what this cable is, and how can I connect a fan to my psu?

Can't see the ends but either SATA or Molex cables.

Looks like a molex cable. You just need an adapter to hookup a fan to it. Here is the adapter.

Yeah, it could be a SATA cable that powers HDD, SSD, Optical drives, etc.

If it is a SATA use this

It's a 4-pin molex cable. It's what hard drives used to use. The last one I think is for floppy drives, I can't completely make it out. Anyways you can find 4 pin molex to fan adapters on Amazon.

You can also just get some splitters to run more than one fan off a motherboard header. You can usually run at least two fans. They are available in 3 pin splitters and 4 pin splitters. Depending on header type. They even make mult-fan splitters. Ones which get the speed signal from the motherboard and power directly from the PSU.

Better off getting a fan splitter cable, that way you will have some control over the fan speed rather than plugging it straight into the PSU where it will run at 100% all the time.
