Building custom cables from scratch
Now that I have my eGPU up and running is time for finishing modding the Akitio Thunder2. I will start by building a custom cable.
- PCI-8pin to PCIE-6+2pin
- Am-Tech Heat Shrink Wire Wrap
- Solder Seal Wire Connector
- Heat gun
- Unused old 12V 1A adapter with 5,5x2,5 barrel plug
I cut off the PCIe extender and the plug (with 5-10cm of wire) and did all the wiring and covered all with a heat shrink tube. The first part of the operation is done. Tomorrow I am gonna find a spot to drill a hole inside the box (near the power socket) and pull the wires through and connect with the 6pin female on the other side of the hole. I still have to choose if I will pose the wires between the enclosure and the motherboard or between the motherboard and the GPU.
Tomorrow I will get some Rubber Grommets that will prettify the setup. I will post the final result once finished.
This endeavour was a BUST. Since the Akitio inner part slides in the outer part, the cable was way to short for me to solder the connectors inside the box. So i started from scratch and from the other side. Meaning that I will start with a 6pin PCI male connecter attached to a 30cm cable (maybe 2cm less since I will cut one socket off). Will pull the wires through the drilled hole (in both of the cases inner/outer) from inside to outside and solder the 8 pin female/barrel plug outside the box. Then will pull the cable back in the case, leaving only the 8 pin soldered part inside.
This hopefully will give me the room to slide the 2 Akitio parts all the way (it has 23cm and the cable should have 25-26cm) so I can remove/update/replace the GPU. I ordered a 40cm long 6pin cable which will replace the 30cm one once it arrives.
Will continue working on Monday ...
- 2 x 30cm 6pin to 8pin PCIe splitter
- old adapter with correct sized barrel plug (5,5x2,5)
- 8pin PCIe extender
After using a file to smooth the edges of the hole and a black marker to darken the metal where drilled, I started by cutting one of the splitters right near the 6pin socket and ending up with a 28cm cable with a male 6pin socket. I also cut the 8pin extender in half and cut the barrel plug adapter and leaving approx. 30cm of cable.
I pulled the cables from inside the box to outside and using heat shrink connectors I connected the cables form the female part of the cut 8pin extender to the cables getting out of the box. In the same shrink tubes I connected the barrel plug cable (watch the polarity!) and shortcut the 8th pin of the PSU (so I don't need the paper pin)
At the end it looked like this:
