What is this connector?

[aahrg]

So I just got my new graphics card (r9 280 windforce), and while installing it, I had to disconnect a bunch of cables from my motherboard to make room for the card. When I went to reconnect them, I found a yellow cable with 4 pins on it that I don't remember seeing when I disconnected my cables. (They were just the front panel and USB cables). Now I don't know what this cable is used for, if I need it, or even where to plug it back into.

 

 

Sorry for the blurry picture, my phone doesn't focus very well. There are 4 open pins and a 5th that is blocked.

It might be for a single USB port. Might, i'm not sure.

 

Edit: I'm probably wrong, follow the wire back to see what it connects too.

Floppy disk? idk

looks like something that goes in a cooler master v series psu

Probably the HDD/PWR LED or the PWR/RST switch.

I had one of these on my old old gpu, it came out a fan. Was never plugged in and fan still worked

Trial and error?

I'm on a prebuilt (I know) PC that i've been upgrading as I go. The cable leads under the non-removable drive tray, and then under the hotswap hard drive bay and cd drive. I think it connects to the front panel, as everything else is plugged in.

The picture is too close, can you take another one a bit further back and also from the side? Also let us know where the other end leads?

Looks like USB

Since it's a prebuilt it will no doubt be a proprietary connector.

It's not actually connected to my gpu, I just disconnected it as I was in the process of putting it in.

It's much smaller than the modular cables that connect to the psu. It's closer to the size of a fan header.

Molex? But most likely some usb header or front panel I/O connector.

It looks like half of a USB connector block. Does your case have a front card reader? most of those use this odd half USB (they're basically a USB device that connects directly)

It does have a card reader, this is probably the most correct answer...

 

Here it is next to a 6 pin pcie cable, for size comparison.

 

Side view as requested

It's definitely a half USB block for the card reader. It will plug into the top half of the USB header where there are 4 pins instead of 5.

Refer to these two images following the colour of the wires to connect it the right way around and you should be fine:

Yep, I just checked back and one of the usb connectors on the mobo is made of the same yellow plastic as the connector. Thanks for your help.
