This article covers Asixxsix PCIE 5.0 ライザーケーブル.

Overview

The Asixxsix PCIE 5.0 Riser Cable is a flexible GPU extension cable designed for PCI Express 5.0 x16 slots, offering up to 128Gbps of bandwidth. It allows you to mount your graphics card vertically, improving airflow and aesthetics while maintaining signal integrity. The 20cm length is ideal for most ATX and ITX builds, providing enough reach to reposition the GPU away from the motherboard.
This cable is backward compatible with PCIe 4.0, 3.0, 2.0, and 1.0, making it a future-proof choice for systems that may later upgrade to a Gen5 GPU. It features a plug-and-play design with no BIOS configuration required, and includes a cable protector to prevent damage from bending or twisting.
Positioned as a mid-range to high-end accessory, the Asixxsix riser cable offers a cost-effective solution for enthusiasts who want to vertically mount their GPU without sacrificing PCIe 5.0 performance.

Compatibility Guide

  • Interface: PCI Express 5.0 x16 (backward compatible with 4.0, 3.0, 2.0, 1.0)
  • GPU Compatibility: All PCIe x16 graphics cards, including RTX 4090, RTX 4090 Ti, RX 8900 XT, and older models
  • Motherboard Compatibility: Any motherboard with a PCIe x16 slot (ATX, Micro-ATX, Mini-ITX)
  • Case Compatibility: Requires a case that supports vertical GPU mounting or a separate mounting bracket
  • Note: The 20cm cable length suits standard mid-tower cases. For full-tower or extra-large cases, measure the distance from the PCIe slot to the desired GPU position before purchasing.

Product Info

Released in late 2024, the Asixxsix PCIE 5.0 Riser Cable is available on Japanese online retailers for approximately ¥11,217 (tax included). Warranty is typically one year from the manufacturer. The cable supports the full 128Gbps bandwidth of PCIe 5.0 x16, with shielding to minimize signal loss and a cable protector for durability. It occupies a value-oriented spot in the PCIe 5.0 riser cable market, offering solid performance at a competitive price.

Best Use Cases

  • High-End Gaming PC Builders: Ideal for vertically mounting an RTX 4090 or similar flagship GPU to improve airflow and showcase the card. The PCIe 5.0 bandwidth ensures no bottleneck with current and next-gen GPUs.
  • ITX/SFF Enthusiasts: In compact cases, a flexible riser cable allows creative GPU placement to maximize space. However, verify that 20cm is sufficient for your specific case layout.
  • Custom Water Cooling Builds: When a large radiator or pump block the primary PCIe slot, this cable lets you relocate the GPU to a more convenient position.
  • Who Should Avoid: If you don't need vertical mounting or are using a PCIe 4.0 or older GPU, this cable offers no performance benefit. Also, if your case requires a longer cable (30cm+), look for alternative lengths.

Things to Consider

  • The 20cm length may be too short for full-tower cases or when the GPU needs to be placed far from the motherboard. Measure your case interior before buying.
  • PCIe 5.0 benefits only apply when paired with a Gen5 GPU and motherboard. On older systems, the cable will run at PCIe 4.0/3.0 speeds, offering no bandwidth advantage.
  • Heavy GPUs like the RTX 4090 require additional support (bracket or stand) to prevent stress on the cable and connector. The cable alone is not designed to bear the card's weight.
  • Competing products from Thermaltake, Phanteks, and Lian Li offer similar specs at varying prices. Compare cable length, shielding quality, and warranty before deciding.

FAQ

Q: Can I use this cable with a PCIe 4.0 motherboard?
A: Yes, it is fully backward compatible. The cable will operate at PCIe 4.0 speeds when used with a Gen4 motherboard and GPU.
Q: Do I need extra support for a heavy GPU like the RTX 4090?
A: Strongly recommended. The RTX 4090 is very heavy; using only the riser cable to support it can damage the connector. Use a dedicated GPU support bracket or a vertical mount kit that secures the card.
Q: What case size is the 20cm cable suitable for?
A: It works well in standard ATX mid-tower cases where the distance from the PCIe slot to the side panel is around 15–18cm. For larger cases, measure first or choose a longer cable.
