Eyeboot 49 Port USB 2.0 Hub 24P ATX PSU 110v/220v
This is a 49 port hub that is capable of reliably supplying 0.5 - 1A per port without overheating or becoming a fire hazard. Comes with usb cable, but PSU is not included. We suggest 400watt PSU if you want to supply 1A to all 49 ports. Has over voltage and over current recover functions.
