Flat black PCIe 5.0 x16 riser cable with 90-degree right-angle connector for vertical GPU mounting

Corn Electronics

Corn Electronics PCIe 5.0 x16 Riser Cable 90 Degree Right Angle

SKU CH-NF27-WB83V

A PCIe 5.0 x16 riser cable with a 90-degree right-angle connector for vertical GPU mounting, delivering up to 78W through a 40-pin design with 10 dedicated 12V pins

Length 150mm

Color Black

  • PCIe 5.0 bandwidth up to 64 GB/s with compatible CPU and GPU
  • Tested throughput of 50 GB/s using silver-plated 30 AWG conductors
  • 78 W power delivery via 10 dedicated 12 V pins on 40-pin connector
  • Double-grounded foil-wrapped pairs suppress EMI for signal integrity
  • 90-degree right-angle design fits vertical GPU mounts with 97–128 mm screw spacing

Compatible hardware for full bandwidth

This PCIe 5.0 x16 riser cable is built for vertical GPU mounting with a 90-degree right-angle connector. It targets builders pairing Intel 13th Gen or newer CPUs with RTX 50 Series or Radeon RX 9000 Series graphics cards on Z790 or newer motherboards. The cable supports backward compatibility with PCIe 4.0 and 3.0 devices.

Sustained signal integrity and power

Each differential pair is double-grounded and individually foil-wrapped to minimise EMI under continuous load. The 30AWG silver-plated copper conductors maintain the tested 50 GB/s throughput without degradation. A 40-pin connector delivers up to 78W via ten 12V pins and six 3.3V pins for stable operation during extended heavy workloads.

Required slot and memory configuration

Verify your motherboard provides a direct CPU-connected PCIe 5.0 x16 slot; chipset lanes will not deliver full bandwidth. The system also needs 32GB of dual-channel DDR5 6000 memory or faster. Mounting holes adjust from 97 mm to 128 mm to fit common 98, 108, 121 and 125 mm spacing.

Questions about this item

How much power does the 40-pin connector deliver to the GPU when the riser runs all day?

The 40-pin connector supplies up to 78W through ten 12V pins and six 3.3V pins for stable power under heavy loads.

Which CPU, motherboard and memory must I already own for this riser to work at PCIe 5.0 x16?

You need an Intel 13th Gen or AMD Ryzen 8700 CPU, a Z790 or newer motherboard with a direct CPU-connected PCIe 5.0 x16 slot, and 32GB dual-channel DDR5 6000 memory.

Will my RTX 4090 or RX 7900 run at PCIe 5.0 speeds through this 90-degree right-angle cable?

The cable is backward compatible with PCIe 4.0 and 3.0 GPUs such as the RTX 4090 and RX 7900, but full 5.0 bandwidth requires an RTX 50 series or RX 9000 series card.
