980W Power Supply for Mac Pro A1186 2007 2008

High-power 980W internal power supply assembly for the classic aluminum Mac Pro tower (A1186). Designed for original 4-core and 8-core configurations with multiple hard drives, PCIe graphics cards, and high CPU loads. This unit is a direct replacement for the 980W PSU used in 2007–2008 Mac Pro towers and supports the full factory power envelope.

This 980W power supply is built for the A1186 Mac Pro chassis and delivers stable +12V rails for dual CPUs, high-end GPUs, and multiple storage devices. It uses the original Mac Pro style 10-pin and 12-pin harness connections and matches the physical form factor, mounting points, and airflow path of the factory unit.

Ideal as a replacement for a failed PSU or for restoring a classic Mac Pro tower to reliable service.

⚙️ Fit Notes

• Designed only for the classic aluminum tower with model number A1186 (side panel label); not suitable for later A1289 Mac Pro towers (2010–2012) or any cylindrical / “trash can” Mac Pro.
• Before replacing the PSU:

• Shut down the machine and disconnect the AC power cable.
• Allow several minutes for internal capacitors to discharge.
• Remove all side and internal access panels as per OEM service guides.

• Reuse the original mounting screws and follow the original cable routing to avoid pinching cables or obstructing airflow.
