header Unknown header

[nerd1995]

Got a new mobo, a ROG STRIX B450-F GAMING II and there is an unlabeled header on it. Not even the manual tells me what the f it is. So if anyone knows what it is, lemme know.

Looks like motherboard USB 2.0 header.

Perhaps for RGB control?

Or it's just a USB header, used for internal USB devices such as card readers that go in the floppy bay.

It's a pretty unusual position on the motherboard. I'd figured the USB headers would be along the bottom edge of the motherboard or the right side by the 24-pin ATX power port.

Should i try to plug the iao in it?

No, that does not go there. You will kill your AIO and/or board. Plug it onto a fan header.

no , find out what the header is before plugging anything into it

The kraken needs an usb 2.0 header, and funny thing that this mobo only got one and that is already in use.

There is 0 info on it, thats why im asking.

Might try going through the listed I/Os on the motherboard spec sheet:

1 x M.2 Socket 2 with M key, type 2242/2260/2280/22110 storage devices support (PCIE 3.0 x 4 mode)    //Nope
1 x USB 3.2 Gen 1(up to 5Gbps) connector(s) support(s) additional 2 USB 3.2 Gen 1 port(s)                     //Nope
1 x M.2 Socket 1 with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x 4 mode) //Nope
1 x CPU Fan connector(s)                                      //Nope
1 x CPU OPT Fan connector(s)                            //Nope
3 x Chassis Fan connector(s)                             //Nope
1 x AIO_PUMP connector                                  //Nope
1 x Addressable RGB header                          //Nope
1 x AAFP connector                                        //Possible but prob. not (would be labeled and is also for front panel)
2 x Aura RGB Strip Header(s)                        //Nope
1 x USB 2.0 connector(s) support(s) additional 2 USB 2.0 port(s)             //Maybe but prob. not
1 x TPM header                                                  //Nope
1 x COM port(s) connector(s)                             //Possible
6 x SATA 6Gb/s connector(s)                             //Nope
1 x 24-pin EATX Power connector(s)                  //Nope
1 x 8-pin ATX 12V Power connector(s)                 //Nope
1 x System panel(s)                                           //Nope
1 x Thermal sensor connector(s)                     //idk but is not likely (2pin)
1 x Clear CMOS jumper(s)                             //Nope

So conclusion is its probably a COM port? Try and find that on the board. If you cant find it, thats probably it. 

Port example: https://superuser.com/questions/1367908/why-are-my-motherboards-com-headers-different-sizes and its similar positioning + looks (1 pin missing to the end) so its probably COM

From the pin arrangement it looks to be a front panel USB connector.

Its on the bottom next to the tpm port

I was thinking the same, but wasn't sure. So i was like lets ask before i fuck it up.

Oh OK. my bad. Thought you meant the pump. Yes that can plug in there!

It's not a USB header, the missing 10th pin is on the wrong side.

 

It's a COM serial header. Used to flash the BIOS maybe?  I'm guessing the chip next to it is the BIOS.

If you don't know what it's for you don't need to use it. No, you cannot plug your AIO in to it.

I'd put my money on that being the case. Looks like a COM port to me too. Though the lack of a label is confusing. Probably just for internal use.

I have the same connector on my Chinese motherboard and it's labelled debug (I didn't know you can flash bioses with it.) Although the pins are much smaller.

There is the COM port.

On this one you have a dedicated usb port for it tho.

Then just leave it as is (I would probably plug it in and test it but I don't want to risk damaging other people's hardware)

You can't cuz the missing pin is on the wrong side.

You can still plug it in backwards by just flipping the cable.

How would that make it work? It's pinned incorrectly for USB 2.0.

@nerd1995Maybe ASUS customer service will tell you.
