The PEXP16-SX-16/4 is a PCI Express X4 lane convertor. Connect a PCI Express x16 card to a X4 slot on your motherboard.
Ideal for video cards or for motherboards that do not provide enough or any PCI Express x16 slots
If your motherboard only has a PCI Express X4 slot, this adapter will allow you to install a PCI Express X16 on it. However your PCI Express X16 card will run at the X4 bus speed. This extension adapter is designed to provide enhanced compatibility between motherboards and a variety of PCI Express expansion cards, and is the perfect solution for converting an unused X4 PCI Express slot to accommodate x2, x4, x8, x12 or x16 PCI Express cards.
Please note that this lane converter may not be compatible with some higher end video cards and workstation cards. Returns for incompatibility issues are subject to 15% restocking fee.
Other combinations of lane reduction adapters are possible with slight modifications, upon request.
