Surveying the community for preferences in Dell DA-2 PSU Easy Power Adapter ...
I spent way too much time across the past few months learning to wire up my own, easy PSU adapter to plug in to everyone's favorite Dell DA-2 PSU and power a variety of DIY and eGPU projects.
I'm looking to you guys (and anyone else that will listen) to see if it's worth trying to bulk-order some decently crafted cables to hook these bricks up to our DIY projects and eGPU's instead of telling everyone to jam paperclips into their wiring harnesses and see how well these things pass TSA when traveling. 🙂
Just three questions if you have a moment:
1. Proper 8-Pin Female receptacle does not exist for cabling. The smallest, nearest part has 12 Pins on the connector.
If I can cut them down to 8 and then shrink-wrap over the plastic exterior housing (nicer texture, grip, appearance) is it worth it? Or does everybody not mind the empty 4-pins at the end and are just fine with the 12-pin?
2. I'm inclined to make the thing under a foot long, so it just snaps in between your PSU plug and your own wires or adapters to your device.
Shorter or longer cable is better? How long would you *want* it?
3. For the Male plug end, PCIe 6+2 pin male header or just a 6-Pin with three 12v wires? Does anybody care about the +2 ground wires dangling off this if they're plugging in more PCIe splitters or adapters upstream anyways?

I am waiting on my Xbox One Psu and a spare 24 pin to 6 pin adapter that usually comes with the EXP GDC. That is easier to wire and plug straight in to the EXP once I splice it up by replacing the fast-on connector built in the xbox one connector.
As with your original query of a "female receptacle", you can splice one up from a 24pin ATX extender. You need to do some patient cutting with an exacto but you can achieve a sizable result when you shrink wrap it pretty.
Using the other end of the extender (the male plug), you can wire a switch and a 6pin/8pin molex as needed. This takes the hassle of using a splitter I believe. I wish I had easy access to Dell Da-2 units so I can test all this but in theory should make enough sense to work okay.

There are websites that sell connectors, crimpers, pins, and cables.
