8pin PCI-E Sleeved Cable Extension

  • All of our custom sleeved cable extensions are hand assembled to order only by our professional sleever. We only use the highest quality materials including our very own premium Teleios sleeve. This ensures consistency throughout each individually sleeved wire that makes up the cable.
  • The highest quality UL1007 18AWG wire is used on all of our extension cables.  This allows us to train our sleeved cables to create a stunning 180 degree curve which we are well known for. This makes installing the cables easy, and allows for the cable to bend effortlessly to the back or behind the components to attach to your existing power supply cable.
  • All of our extensions are made in the heat shrink less style for a clean, and desirable look.
  • Many of our custom cables are used by top entities such as Intel, NVIDIA, EK Water Blocks and more! Buy knowing you are receiving a high quality product from a well reputable company.

These are extensions only, and can be used with any existing 8pin PCI-E power supply cable.

Extension is 12″ in length.

Design your own custom sleeved extension today!

Please allow a few business days for your order to be processed.

Here is how to get started:

We have developed a simplistic way to customize which colors you want for your extension. Below is an image that represents the end that plugs into your GPU. It is numbered 1 – 4. Each number represents that wire, and the wire underneath on the 8pin PCI-E since most choose the same color for the wire underneath. Simply choose which color you want by selecting it with the drop downs below to that of its correlated number in the image.

    They Look Nice.The cables look nice. There is something wrong with this one, or the 6 Pin that go to my Video card. After installing them, I occationaly get an error that reflect not power to my video card. I have ordered new extensions from i different supplier. I have NOT given Mainframe the chance to correct the problem that's why it is a 2 star rating and not one star.

    Top notch product. Got two of these and am so happy with how they turned out. The green perfectly matches an Nvidia theme and the natural curve stops the cables from splaying, and so do not require cable combs to keep tidy. Perfect.

    I ordered two PCI-E 8-Pins and one PCI-E 6 Pin extensions about 9 days ago and I had them in the mail this morning in Switzerland. I was really surprised about that speed delivery. The cables are just perfect. They look amazing and work. What more can I ask. I’ll definitly order extensions for my next project from mainframe custum. Great work!

    This is a beautiful piece of kit. It doesn't have any combs installed and it doesn't need any. I'd say it has everything it needs any nothing it doesn't. The person who crafted this cable clearly takes pride in his work. Well worth the price and the wait!

    I'll be ordering another one soon!
