Overview

The Cooler Master MasterAccessory PCIe 4.0 x16 Riser Cable V2 is designed for PC builders who want to vertically mount their graphics card without sacrificing any performance. Supporting the full PCIe 4.0 specification, this 200mm cable delivers over 64Gb/s of bidirectional bandwidth at a 16GT/s bit rate, ensuring that even high-end GPUs operate at their maximum rated throughput. The cable is also fully backwards-compatible with PCIe 3.0 hardware, making it a versatile addition to both current and older builds.

Build quality is a clear priority in this design. The 30 AWG copper wires are individually EMI-shielded to prevent electromagnetic interference from degrading signal quality, while gold-plated pin connections provide durable, corrosion-resistant contact points rated at 400g retention force per pair. The multi-layer coated PCB is engineered to perform reliably under sustained thermal loads, and the revised TPE cable sleeves offer improved flexibility over earlier versions, making the cable easier to route through tight spaces. A protective ABS casing covers the GPU-side connector for added durability. Whether you're building in a compact ITX case or showcasing your GPU in a full tower, this riser cable provides the reliable link between motherboard and graphics card that a vertical mount demands.

Key Features

PCIe 4.0 compatible: The Gen 4.0 riser cable delivers double the PCIe 3.0 bandwidth, fully supporting backward compatibility, and transfer rates of over 64Gb/s (bi-directional) with PCIe 4.0 devices at 16GT/s bit rate

Ultra Durable PCB: The multi-layer coated PCB provides best-in-class performance under high thermal loads, cable flex, and moisture resistance.

Heavy Duty Shielding: EMI shielded 30 AWG copper wires ensure minimal signal delay and interference-free operation from electromagnetic interference.

Gold-Plated Pin Connections: Gold-plated PCI pins offer maximum durability, rated with a retention force of 400g per contact pair.

New Ultra-Flexible Cable Sleeves: The revised TPE cable sleeves offer maximum flexibility and durability, perfect for the tightest cable routing jobs.

Pros & Cons

👍 Pros

  • Full PCIe 4.0 x16 bandwidth with over 64Gb/s bidirectional throughput ensures zero performance loss
  • EMI-shielded 30 AWG copper wires minimize signal interference for stable operation
  • Gold-plated pin connections rated at 400g retention force per pair resist loosening over time
  • Ultra-flexible TPE cable sleeves simplify routing in tight case layouts
  • Multi-layer coated PCB maintains reliability under high thermal loads

👎 Cons

  • 200mm length may be too short or too long depending on your specific case and mounting configuration
  • Does not include a vertical GPU mounting bracket — sold separately or must be built into your case
  • PCIe 4.0 specification will bottleneck future PCIe 5.0 GPUs to Gen 4 speeds
  • Rigid connector ends require careful alignment during installation to avoid pin damage

Frequently Asked Questions

No, this cable supports the full PCIe 4.0 x16 bandwidth of over 64Gb/s bidirectional, so your GPU will operate at its rated performance without bottlenecking.
Yes, this riser cable is fully backwards-compatible with PCIe 3.0 devices. It will operate at PCIe 3.0 speeds when connected to older hardware.
The cable is 200mm (approximately 7.9 inches) long. Measure the distance between your motherboard's PCIe slot and the vertical GPU mount position in your case to confirm fitment before purchasing.
Yes, this is a riser cable only. You will need a case with a built-in vertical GPU mount or a separate vertical mounting bracket to position your graphics card vertically.
The cable will physically connect to PCIe 5.0 cards, but it will operate at PCIe 4.0 speeds since the cable is rated for Gen 4.0.
