PCIe 4.0 riser kábel CableMod CM-CAB-PC4S-30K-R — 30 cm

CableMod PCIe 4.0 riser cable CM-CAB-PC4S-30K-R — 30 cm is a flexible PCI Express extension designed to carry PCIe 4.0 signaling over a 30 cm length. It enables relocation or vertical mounting of a graphics card or other PCIe devices while preserving high-speed bandwidth and signal integrity required by PCIe 4.0. The cable is intended for custom PC builds, test benches, and compact enclosures where motherboard slot alignment or clearance constraints require a reliable extension.

Advantages

This 30 cm riser cable supports PCIe 4.0 signaling, offering compatibility with devices that use the PCIe 4.0 standard. Its flexible construction simplifies routing in small form-factor cases and allows clean, space-saving installations for vertical GPU mounts or relocated cards. The cable is engineered to minimize signal degradation over the extended length and to maintain stable data transfer rates suitable for high-bandwidth GPUs and expansion cards.

Suitable for

• Custom PC builds with vertical GPU mounting
• Test benches and development rigs requiring flexible card placement
• Small-form-factor or compact cases with restricted space around PCIe slots
• Upgrades where motherboard layout prevents direct PCIe device installation

Key specifications

• Interface: PCI Express (PCIe) extension supporting PCIe 4.0 signaling
• Length: 30 cm usable cable length
• Connector types: standard motherboard PCIe x16 edge connector to PCIe x16 slot connector for device
• Flexible cable construction for routing and vertical mounting
• Designed to preserve signal integrity for high-bandwidth devices

How to use

Install the cable by seating the motherboard-side PCIe connector into the motherboard PCIe x16 slot and then attaching the device-side connector to the graphics card or expansion card. Ensure both connectors are fully and evenly inserted and that any retention mechanisms on the card or bracket are secured. Route the cable to avoid sharp bends and keep it clear of cooling fans and heat sources. Verify system boot and device recognition in BIOS or operating system after installation.

Recommendations

For optimal performance, avoid folding the cable tightly or placing heavy objects on it; maintain gentle curves and secure the cable to prevent movement. Confirm that your case and GPU mounting configuration provide adequate airflow, and check motherboard BIOS settings for PCIe slot configuration if device enumeration issues occur.
