Internal power cable CORSAIR CP-8920451 — 8-pin EPS12V to 8-pin ATX12V, straight connector

CORSAIR CP-8920451 is an internal power cable that converts an 8‑pin EPS12V plug to an 8‑pin ATX12V plug using a straight connector design. It is intended to route CPU or GPU power between compatible Type 5 CORSAIR power supplies and motherboards or add‑on cards requiring an 8‑pin CPU/GPU power feed. The cable is finished in white sleeving for a neat appearance and improved cable management during PC assembly or upgrades.

Advantages

The cable provides a direct, single‑cable connection between EPS12V and ATX12V power ports in systems that require an 8‑pin feed. Straight connector geometry simplifies routing in tight spaces and helps maintain consistent contact alignment. White sleeving creates a clean visual contrast inside the chassis and aids organized cable runs without affecting electrical performance.

Suitable for

• Connecting Type 5 CORSAIR PSUs to motherboards that require an 8‑pin ATX12V CPU power connector
• Powering add‑on cards or adapters that accept an 8‑pin ATX12V input from an EPS12V source
• PC builds and upgrades where cable appearance and neat routing are important

When it may not be suitable

This cable is not appropriate for systems that do not use an 8‑pin EPS12V or 8‑pin ATX12V interface; it will not adapt between different pin counts or connector types. It also does not convert voltage or change power delivery specifications, so it must be used only with compatible power supplies and devices rated for the same power standard.

Key specifications

• Connector A: 8‑pin EPS12V (straight)
• Connector B: 8‑pin ATX12V
• Form factor: straight connector
• Colour: white sleeving

How to use

Power off the system and unplug the power supply before connecting the cable. Insert the 8‑pin EPS12V end into the matching PSU header and plug the 8‑pin ATX12V end into the motherboard or add‑on card power inlet, ensuring correct orientation and secure seating. Route the cable to avoid sharp bends and keep it clear of fans and heat sources. Reconnect power and verify system operation.

What to consider before purchase

• Ensure both the power supply and the target device use compatible 8‑pin EPS12V and 8‑pin ATX12V connectors
• Confirm that a straight connector form factor fits your case routing and motherboard layout
• Verify that the cable colour and sleeving match your desired build aesthetics

Usage recommendations

Install and route the cable with gentle curves, avoid excessive tension, and check connector seating after first power-up to ensure reliable power delivery and tidy cable management.
