COMeap Dual Mini 6 Pin to 8 Pin PCI Express Video Card Power Adapter Cable for Mac Pro Tower/Power Mac G5 15-inch(38cm)

Works great for my rx 570 in mac pro 2008/3,1

I recently upgraded my old graphics card in the mac pro 5,1 to the rx 580 and needed an external power cable to connect it to. This cable is cheap, but works well and gets the job done. It was easy to install, and the blue and black look pretty cool.

Liked everything about this. Working perfect

Yup it works! Upgraded the GFx card and needed the extra juice so I bought this cable. Works great.

Just about anybody seeking to upgrade their 2010-2012 Mac Pro to make it compatible with Mojave will need to upgrade their graphics card. For my upgrade I selected the Radeon RX580 graphics card from the top of the list recommended by Apple. This card requires more power than the older cards and requires a cable capable of delivering the extra power. The upgrade went smoothly and this cable fits well and works great.

These worked in my Mac Pro early 2008 3,1 to power an AMD rx 590. Unfortunately I couldn’t get the driver situation worked out with my patched Mojave install, so I get a black screen, but it worked just fine in the installer screens. ;) if you have an older Mac Pro and you want to install a video card that requires more power, this is a solution that will do well for you The cables are high quality as well as the clips and I see them lasting for a long time. Now I just need to get the driver situation sorted out…

Does it's job perfectly. I wanted to upgrade the video card in my Mac pro and this cable provided the power that my new card needs at a reasonable price. If I ever need something like this again, this is the cable that I will buy.
