Premium PCI-E 4.0 x16 Riser Cable

This 300 mm flexible extender connects a graphics card to a motherboard slot using the PCI Express 4.0 x16 interface. The cable is 1.3 mm thick and weighs 0.19 kg, making it suitable for tight routing inside custom chassis. Improved EMI shielding with conducting polymer protects signal integrity at up to 16 Gbps. The black thermoplastic and polyethylene jacket resists wear during installation.

Compact Builds and Custom Loop Routing

Builders who need to position a GPU away from the primary slot for vertical mounting, water-block clearance or small-form-factor layouts will benefit from the 300 mm reach. The male-to-female connectors allow direct plug-in without adapters. Systems that require longer runs or multiple riser segments should look at other lengths, as this unit is fixed at 300 mm.

PCI Express 4.0 x16 Bandwidth Support

The cable is specified for PCI-E 4.0 x16 operation, delivering up to 16 Gbps per lane across the full 16-lane width. This bandwidth ceiling determines whether the riser can saturate modern GPUs without throughput loss. Verify that both the motherboard slot and the graphics card operate at PCI-E 4.0 x16 to match the cable rating.

Questions about this item

How do I confirm the 300mm riser is delivering PCI-E 4.0 x16 bandwidth after installation?

Verify the link runs at 16 Gbps in your motherboard BIOS or GPU-Z; the cable’s EMI shielding and conducting polymer are designed to maintain that signal integrity.

What ships with the CABLE-PCIE16X40-30 and what must I source separately?

The package contains one 300mm male-to-female PCI Express x16 extender with a cable protector; you still need a compatible motherboard slot and graphics card.

Which length should I choose for a compact build using this Athena Power riser series?

The 300mm version suits most small-form-factor layouts; longer options exist if your GPU mounting point sits farther from the slot.
