GPU riser cables typically employ different connector configurations on the GPU end (connecting to the graphics card) and the motherboard end (connecting to the PCIe slot). Our three primary interface types are:

1. Female Reverse

2. Straight (as for Straight Male)

3. Dual Reverse

Female Reverse	“Female” refers to an enclosed socket with an internal receptacle (i.e., a slot for PCIe pins). “Reverse” (right‐angle) indicates that the socket is bent 90° relative to the cable’s main axis, allowing the mating face to face perpendicular to the cable’s route.
Straight Male	“Male” refers to the exposed gold fingers or insert pins that directly plug into a standard PCIe slot. “Straight” indicates that the pins extend in line with the cable, without any angular deviation.
Dual Reverse	Both ends of the riser cable incorporate a 90° reverse bend: GPU-Side: Female socket bent 90°, facing perpendicular to the cable direction. Motherboard-Side: Male plug bent 90°, also oriented perpendicular to the cable.

Selecting the Appropriate Length and Configuration

Select the appropriate GPU riser cable length by referring to the provided table, based on your motherboard and GPU dimensions, as well as your assembly method.

Third-party Cable Advisory
When using custom cables:

• Pre-bent cables are strongly recommended to prevent signal degradation from improper bending.

• Avoid sharp bends (>90°) and maintain minimum 30mm bend radius for Gen4/Gen5 PCIe compatibility.

• Verify impedance rating for high-speed signal integrity.
