PCI-E interface expansion, effectively solving the insufficient PCI-E interface, this product can be expanded to 4 PCI-E.With plug-in design, it can be directly connected to the motherboard interface without an extension cord, and can be fixed on the chassis, which greatly improves the stability and reliability The main control board adopts the PCI-E interface direct power supply mode, without an external power cord, so that the main control board power supply is not interfered by the outside world, and the stability is higher Reduce the number of adapters and adapter cables. One line goes directly to the interface, effectively reducing interface interference and line loss, ensuring data reliability, and improving work efficiency.No need for external power supply, plug and play, more stable.Product name: PCIE expansion cardModel: PH48Product interface: support PCI-E X1 (compatible with X4X8X16) interfaceNumber of interfaces: PCI-EX1 interface*4System: os/ Windows/ LinuxColour: blackMaterial: PCB + metalSize: 12x6.5x5.5cmPackage Contents:1 * Full-height expansion card1 * Half-height baffleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
