I need to add a RS232(Serial Port) connection to my pc, and unfortunately I'm unable to use RS232 to USB adapter, only direct RS232 connection, I have seen this item: https://www.aliexpress.com/item/MYLB-DB9-RS232-to-10-pin-Ribbon-Cable-Connector-Adapter/32735919280.html? and that seems nice, but I have no idea how to connect something like that, I'm pretty sure that it shouldn't be connected through the PSU, as I don't recall seeing anything similar from a PSU, so I assume you need to connect it directly to the motherboard somehow, which I believe is correct, but still, I don't know how to connect it to the motherboard, and if I even can, here are pictures of my motherboard:

My motherboard is MSI B75MA-E33, so Im not even sure its the correct place to ask, but hopefully someone can help me here, thanks! :)
