Add more USB to your life! From 2 more USB 3.0 slots to 4 USB 3.0 slots, to even a type-C connector, this is the page to go to for all your connection needs! Most motherboards have enough I/O and USB ports for the average user, but assuming you have a UPS connected, an external GPU dock, maybe the keyboard and mouse, a thumb drive, and a charger for your phone and that's still not enough, you can have one of these cards installed onto your system! The 2 port USB 3.0 is selected by default, but you may change it below! Order this item multiple times for more cards to be installed (for a maximum of...well it depends on the system, ask us how many cards can be installed in any system that catches your eye!)
Pictures in order:
1) USB 3.0 (x2 ports) (Uses a 4-pin Molex, which most power supplies have anyways)
2) USB 3.0 (x4 ports) (Also uses a 4-pin Molex)
3) USB 3.0 (x1 port) and USB 3.1 Type-C (x1) (Uses SATA 3, again all power supplies have this)
Also note we have IEEE1394 that can be installed (These are also called "Firewire"), but it isn't listed because that setup may require special parts and adapters. Plus we're not expecting anyone to actually use it.
