To place one or two PCIe cards horizontally. Female ports are physically the size of x16 ports, but their bandwidth is x8

Features :
PCIe Gen 4.0 type riser, for use on a Gen 3.0 or Gen 4.0 port.
If x16 to x8/x8 bifurcation mode is supported: allows two PCIe x8 cards to be connected horizontally.
If bifurcation mode is not supported: allows you to connect a PCIe x16 card horizontally.
PCIe throughput in Gen 4.0 x16 of 32GB/s.
Power supply via 15-point SATA connector.
Riser height (excluding male PCIe connector): 30mm.
Width of female PCIe connectors: 5mm.
Spacing between the two female slots: 20mm.
Total length: 125mm.
