<strong>PCI Express Riser Card PCI-E 1x to 16x 1 to 4 USB Slot Multiplier Hub Adapter for Bitcoin Mining</strong><br /> <strong>Features:</strong><br /> 1. To effectively solve the problem that the main board PCI-E interface is not enough, one interface can be extended to 4 ports.<br /> 2. With the design of the pluggable plate, the main board interface is directly connected without the extension line, and it can be fixed to the chassis. The stability and reliability are greatly improved.<br /> 3. The main control board uses the direct power supply mode of PCI-E interface, and does not need to connect the power line again. It is the main control board electric power is not disturbed by the outside, the stability is higher.<br /> 4. Reduce the number of adapter and adapter cable. One line directly connects to the interface, which effectively reduces the interface interference and wire loss, ensures data reliability and improves work efficiency.<br /> 5. The main board IC and radiator, multiple lines work to solve the heat problem at the same time.<br /> <br /> <strong>Specifications:</strong><br /> Bus interface: PCI-E X1 (compatible x4/x8x/16 card interface)<br /> Interface number: PCI-E-USB interface *4<br /> Product size: approx.120*65*20mm/4.72*2.55*0.78''<br /> System support: DOS, Linux, WIN XP, Win7, Win8, Win10 and so on<br /> <br /> <strong>Note: </strong><br /> Please allow 1-3cm differs due to manual measurement.<br /> Due to the different display and different light, the picture may not show the actual color of the item.
