Review on 🎮 PCI Express Video Card Power Adapter Cable for Mac Pro Tower and Power Mac G5 with Dual Mini 6 Pin to 8 Pin (38cm) by Matthew Owens

They worked in my early 2008 Mac Pro 3.1 to power an AMD rx 590. Unfortunately, I couldn't fix a driver issue with my patched Mojave install, causing me to get a black screen, but it worked fine on the installer screen. ;) If you have an older Mac Pro and want to install a graphics card that requires more performance, this is the solution that suits you. The cables are of high quality as are the clips and I can see they will last a long time. Time. Now I just have to deal with the driver situation...
