This article covers XRIKUI PCIe 4.0 x1ライザーケーブル.

Overview

The XRIKUI PCIe 4.0 x1 Riser Cable is a male-to-female extension for PCI-Express 1X slots. Its compact 10cm length and 90-degree connectors on both ends make it easy to route cables in tight spaces. Supporting PCIe 4.0 with up to 16 Gbps data transfer, it is backward compatible with PCIe 3.0/2.0/1.0. The cable features a tinned copper core for maximum signal speed and a shielding layer of PE insulation and TPE plastic to protect against electromagnetic interference. This accessory is ideal for users who need to reposition x1 devices such as capture cards, 2.5G LAN cards, or RAID controllers to improve case layout and airflow.

Connectivity & Compatibility

This cable plugs directly into a motherboard PCIe x1 slot. The female connector is open-ended, allowing x4/x8/x16 cards to be physically attached, but bandwidth is limited to x1. It is compatible with PCIe 4.0, 3.0, 2.0, and 1.0, working with a wide range of desktop motherboards. Note that it is designed for desktop PCs only; it cannot be used with laptops or external enclosures. The 90-degree connectors help avoid interference with the case when using edge slots.

Product Info

The exact release date is unclear, but the cable has been available on online retailers since around 2024. It is priced at approximately ¥4,232. Warranty details are not publicly specified. The package includes only the cable itself, with no additional brackets or screws. The cable is made of high-quality flexible material, and the PCB is reinforced with bolts and nuts to prevent tearing or short circuits at solder points. Market positioning is entry-level, offering a low-cost, practical solution for specific cable-routing challenges.

Best Use Cases

  1. Small form-factor PC users: In Mini-ITX or Micro-ATX cases, PCIe slot placement can cause interference with other components. This riser allows you to relocate an x1 card to a free space, avoiding conflicts. Best suited for low-bandwidth devices like sound cards, USB expansion cards, or capture cards. Not suitable for GPUs or NVMe SSDs that require x16 bandwidth.
  2. Airflow optimization: Placing an x1 card next to a GPU can expose it to GPU exhaust heat. By using this cable, you can move the card to a cooler area, improving overall system cooling. Do not use this as a GPU riser; it is x1 only.
  3. 90-degree adapter use: When a card in an edge PCIe slot interferes with the case side panel or cables, the 90-degree connectors allow the card to sit parallel to the motherboard, preventing interference. Not for users needing high-bandwidth connections for gaming GPUs or fast NVMe SSDs.
