Front-panel USB 3.0 hub for 3.5" bays
The IOGEAR U3-109 adds four USB 3.0 ports to a desktop front panel through a standard 3.5-inch drive bay. It connects to the motherboard via a 20-pin internal header and draws auxiliary power from a SATA connector. The hub uses a GL3520 chipset and supports USB 3.0, 2.0 and 1.1 speeds. It is intended for builders who want front-access USB ports without using a 5.25-inch bay.
Thermals, noise and power draw
The adapter has no active cooling and produces no audible noise during operation. Each port can deliver up to 900mA for device charging or operation, with total power supplied through the SATA connection. Power consumption scales with the number of attached devices and their individual draw. No fan or thermal management is required for normal desktop use.
Single specification that decides fit
The hub requires a motherboard with an available internal USB 3.0 20-pin header and a spare SATA power connector from the power supply. If the board lacks the 20-pin header or the PSU has no free SATA lead, the hub cannot be installed. Builders without those two connections should not buy this product.

Questions about this item
How do I connect the 20-pin motherboard header and the SATA power cable when installing the U3-109 into a 3.5-inch bay?
Slide the hub into a free 3.5-inch front bay, secure it with screws, plug the 20-pin connector into the motherboard USB 3.0 header, then attach the SATA power lead from the PSU to the hub's SATA socket.
Will the GL3520 chipset or the four USB ports need any firmware updates or periodic cleaning?
The GL3520 chipset runs on fixed firmware with no user updates; only occasional dust removal from the port openings is needed.
Which limit appears first when all four ports run at 5 Gbps simultaneously?
The 900 mA per-port current ceiling is reached first; each port is capped at 900 mA by the hub design.
