If you have a Nvidia RTX 3080 Founders Edition you'll know how fugly the power cable adapter is. However if you have a compatible EVGA power supply EVGA sells their own power cable that goes straight from the power supply to the graphics cards new 12pin connector without using the adapter.

However I wanted to tidy that cable a little more so I designed this guide. It mounts between the heat sync fins and the outer shroud of the graphics card. There are points to cable/zip tie the inner cables and notches for the cable combes.
