Upgrade or replace the main motherboard power harness in your Dell workstation with this Genuine Dell 24-Pin Main Power Cable (DP/N 0654MT).
This OEM Dell cable is required when using Dell’s proprietary 850W or 1000W modular power supplies, converting the PSU’s multi-pin outputs into a standard 24-pin ATX motherboard connector.
This cable is essential for powering the motherboard in Dell Precision systems and is NOT compatible with standard ATX power supplies.
It is designed specifically for Dell’s modular PSU architecture and ensures correct pinout, stable voltage delivery, and full system compatibility.
