Internal power cable CORSAIR CP-8920389 — 8-pin (6+2) PCIe, straight connectors, 650 mm, black

CORSAIR CP-8920389 is an internal PSU-to-GPU power cable with an 8-pin (6+2) PCIe connector configuration and straight, two-sided plugs. The cable is sleeved in black triple-layer mesh paracord and measures 650 mm, providing a tidy direct power connection for graphics cards and other PCIe devices in desktop system builds or upgrades.

Advantages

The sleeved triple-layer mesh paracord construction improves cable flexibility and presents a professional, uniform appearance inside the case. Straight connectors allow for a simple, space-efficient routing path and the 6+2 configuration offers compatibility with both 6-pin and 8-pin PCIe power sockets on graphics cards.

Suitable for

• Connecting a power supply to discrete graphics cards that accept 6-pin or 8-pin PCIe power
• System builds where a 650 mm cable length is required for neat routing
• Replacing or extending existing PSU-to-GPU cables in mid- to full-tower PC cases

When it may not be suitable

This cable is not suitable for power supplies or graphics cards that require angled or right-angled connectors, or for systems needing shorter or substantially longer cable lengths than 650 mm. It also is not a device-specific adapter for non-PCIe power standards.

Key specifications

• Connector type: 8-pin (6+2) PCIe
• Connector orientation: straight (both ends)
• Cable length: 650 mm
• Colour: black
• Sleeving: triple-layer mesh paracord

How to use

Power off the system and disconnect from mains before installing. Route the cable from the PSU to the graphics card, ensuring the straight connectors can reach the PSU and GPU sockets without strain. Attach the 6+2 plug to the GPU power port, combining the 6-pin and 2-pin portions as required for an 8-pin socket or using only the 6-pin portion where applicable. Confirm a secure, fully seated connection before powering the system back on.

What to consider before purchase

• Confirm your graphics card power socket type (6-pin, 8-pin or both) and physical clearance for straight connectors
• Measure available routing distance in your case to ensure 650 mm is sufficient
• Verify compatibility with your PSU connector layout and any modular cable pinouts

Usage recommendations

For best results, route the sleeved cable along case edges or behind the motherboard tray to maintain airflow and a neat interior. Avoid tight bends at connector ends and secure the cable with ties to prevent strain on connectors.
