Riser ribbon cable Supd G89.OE776PI4L27.00 PCIe 4.0 270mm black

Riser ribbon cable Supd G89.OE776PI4L27.00 PCIe 4.0 270mm black is a flexible PCI Express extension that enables relocation and repositioning of PCIe cards inside a computer chassis. At 270 mm length and in a slim ribbon form factor, it supports PCIe 4.0 signaling for high-speed data transfers while allowing compact and angled installations. The cable is intended for applications where space constraints or unconventional mounting make a standard rigid riser impractical.

Advantages

The ribbon design offers a low-profile, flexible connection that simplifies routing in tight enclosures and around components. Compatibility with PCIe 4.0 signaling maintains bandwidth and signal integrity typical of modern expansion cards. The 270 mm length provides reach for relocated cards without excessive slack, and the black finish reduces visual distraction in visible builds.

Suitable for

• Compact PC builds and small-form-factor cases
• Test benches and development rigs
• Custom mounting or angled GPU/PCIe card installations
• Systems requiring flexible cable routing to avoid interference

Key specifications

• Interface: PCI Express compatible, PCIe 4.0 signaling
• Length: 270 mm
• Form factor: Flexible ribbon cable
• Color: Black
• Intended use: External internal card extension for relocation and orientation

How to use

Install the riser by seating one end into the motherboard or host PCIe slot and the other end into the target card’s connector, ensuring alignment and full insertion at both ends. Route the ribbon to avoid sharp bends and secure it with available cable ties or mounting points if necessary to prevent movement. Verify that the card is properly powered and that any retention clips or screws are used where applicable to maintain a stable mechanical connection.

Usage recommendations

For optimal signal integrity, avoid tight 90-degree folds and excessive stress on the cable. Use in systems designed for PCIe 4.0 bandwidth when possible; if installed where mechanical strain could occur, secure the cable to fixed points and confirm card seating after initial power-up.
