Hubs for your custom PC are often simply multipliers, allowing the use of multiple loads off of a single output. Sometimes they function in more of a consolidation role, such as a multifunction hub that brings USB and audio ports to a single spot in the front of the PC case. Hubs can range from 3- and 4-pin fan power hubs to multi-port USB hubs both internal and external. They serve many functions as needed by the user. TITAN RIG carries multiple power and USB hubs for your needs.
