PCIe Power Cable for Mac Pro and G5

This cable connects a logic board mini 6-pin connector to a graphics card with a standard 6-pin PCIe power input. It is built for owners of Power Mac G5 and Mac Pro tower systems who need to run compatible ATI Radeon or nVidia GTX cards. The 11.5 inch length fits the internal routing of those chassis.

Steady Power Delivery Over 18 AWG Wire

The 18 AWG conductors maintain stable voltage under continuous GPU load rather than only during brief peaks. Male-to-male terminals lock into both the board and the card, preventing disconnection when the system runs hot for extended periods. The 29 cm assembly includes both connector housings in its measurement.

Limited to 6-Pin Mini PCIe Source Boards

This adapter works only on Macs that expose a mini 6-pin PCIe power header on the logic board. It cannot supply power to cards requiring an 8-pin connector or to systems lacking the proprietary mini connector. Buyers with newer Mac Pro models or non-Apple workstations need a different power solution.

Questions about this item

Does the 18 AWG wire generate noticeable heat when the cable runs continuously?

The 18 AWG conductors are rated for the current a 6-pin PCI-e connector delivers, so the cable stays cool during all-day use.

What must the host computer provide for this cable to function?

The logic board needs a mini 6-pin power output; the cable plugs directly into that socket.

Will this work with an older Radeon 4870 kept from a previous build?

Yes, the 6-pin PCI-e male end fits the 4870's power connector, and the mini 6-pin end connects to compatible Mac Pro or Power Mac G5 logic boards.
