Power cable NVIDIA 2×8-pin PCIe (male) to 16-pin CEM5 (male) – 930-00030-1633-000

This NVIDIA power cable converts two 8-pin PCI Express (male) connectors into a single 16-pin CEM5 (male) connector. Designed to bridge older or modular power supplies with modern graphics cards that use the 16-pin CEM5 power input, the cable provides a straightforward physical adaptation to deliver required power without cutting or altering original PSU wiring. The cable is intended for use where the power supply has two available 8-pin PCIe power outputs and the graphics card accepts a single 16-pin CEM5 connector.

Advantages

The adapter enables compatibility between power supplies and graphics cards that use different connector formats while preserving the original PSU cabling. It simplifies installation by combining two separately routed 8-pin PCIe feeds into one standardized CEM5 plug, reducing the need for additional adapters or rewiring. The product is compact and purpose-built for safe power delivery when used with compatible components, helping maintain secure electrical contact and mechanical fit during installation.

Suitable for

• Upgrading a system where the GPU requires a 16-pin CEM5 input but the PSU has only 8-pin PCIe outputs
• System builders assembling desktops with modern graphics cards and older or modular PSUs
• Temporary or permanent installations where a single CEM5 connection is preferred for cable management

Key specifications

• Input connectors: two 8-pin PCI Express (male) connectors
• Output connector: one 16-pin CEM5 (male) connector
• Purpose: power cable adapter for graphics cards and power supplies
• Connector orientation: fixed, male-to-male adapter cable
• Cable construction: insulated multi-conductor assembly designed for GPU power delivery

How to use

Power off the system and disconnect it from mains power before installation. Locate the two available 8-pin PCIe power outputs from the PSU and firmly insert each into the corresponding 8-pin male connectors of the cable. Route the cable to the graphics card and insert the 16-pin CEM5 male connector into the card’s power input until it seats securely. Re-check all connections for snug fit and clearances with case panels or other components before restoring power to the system.

Recommendations

Use this adapter only with power supplies and graphics cards that are electrically and mechanically compatible with the specified connectors. Verify that the PSU can supply the required combined current and wattage for the GPU model before connecting. Do not modify or splice the cable; avoid using damaged or frayed cables and ensure proper airflow and secure mounting of the GPU to prevent strain on the connector.
