008S PCI-E Express 1x to 16x USB Riser adapter card Cable molex/6pin/Sata USB 3.1 Extension connector riser60cm

Works better than expected. Use is to have an external PCIe for a Raid SAS controller.

At first, those riser work. But! USB connector on motherboard part SHOULD BE UP, not to the side.If you wanna connect multiple cards together on specialmotherboard with 10-12 pci-e slots, you won't be able to accomplish this mission.Check my photo. Be careful, chose right risers for your motherboard.3 type of power connection is BIG plus.
