The controller card is installed into an available PCIe x16 slot within your computer and can provide up to 80 Gb/s of bandwidth to the expansion chassis. Furthermore, this chassis is built with a universal power supply and a variable speed exhaust fan to provide power and to cool the PCIe cards. Included with expansion chassis are a 3.3' (1m) x16 cable and a host interface controller card.
