The EB3T-DB ExpressBox 3T 3-Slot Thunderbolt 2 to PCIe Expansion Chassis from Magma contains three PCIe slots that connect to a computer through a Thunderbolt cable. It allows you to attach three full length PCIe cards to your Thunderbolt 2 equipped computer, and turns your computer to an audio/video editing workstation or a scientific workstation. The expansion chassis supports high performance workflows, when a Thunderbolt equipped computer is connected to it with PCIe cards for video capture, media transcoding, audio processing, and fast data storage. Since the Thunderbolt is also based on DisplayPort technology, you can daisy-chain a high-resolution display with the expansion chassis.Supports three full length PCIe cardsTwo x8 and one x4 PCIe Gen 2 slots (one slot accommodates x16 card)Thunderbolt 2 connectivity provides speeds of up to 20 Gb/sDaisy-chain up to six Thunderbolt devicesEnd-point device250W power supply with auxiliary power connectorsAttach PCIe cards to Thunderbolt equipped mobile and all-in-one computersExtension of PCIe signals outside the computerPlug and playUse any combination of x1, x4, x8 and x16 PCIe cardsHot-swappable cooling fan and an additional blower for hot cards
