Riser Cable
* Bifurcation is recommended only for advanced users.
Bifurcation is the technology of splitting a single PCIe 16x 3.0 slot into two PCIe 3.0 16x slots with 8x bandwith on each.
Known supported motherboards include Gigabyte Z390 Auros, Z370N; ASRock Z390, Z370, X299, and X99; and most server motherboards.
Please confirm compatability with your motherboard by contacting before purchasing.
Power Supply Cable
* Standard power cable restricts GPU height to 133mm (this prevents some oversized MSI and Zotac cards from being mounted)
** Pigtail power cable mount restricts GPU height to 145mm tall (this allows for taller MSI Gaming and Zotac GPUs)
