US$3 Dell DA-2 to PCIe output splitter

The 220W Dell DA-2 is a common and affordable fanless eGPU power source used to drive many mPCIe/EC and mini AKiTiO eGPU adapter/enclosure solutions. As few enclosures have a Dell DA-2 8-pin input port, in this topic we show how with ~US$3 of parts, a Dell DA-2 PSU output plug can be split into 3xPCIe outputs for standalone use or to be further customized. This is done without the use of any soldering.


Required parts





1. Attach a PCIe splitter to the Dell DA-2 8-pin plug to create 2x PCIe plugs


Using a little force on these unkeyed parts,  attach the female 6P or 8P PCIe splitter plug with the male 8-pin Dell DA-2 output so:

  • PCIe splitter black wires attach to the GND pins (1, 3, 5 on DA-2)
  • PCIe splitter yellow wires attach to the 12V pins (2, 4, 6 on DA-2)




!! warning !! ensure your PCIe splitter does not connect to the leftmost Dell DA-2 REMOTE and SENSE pins shown above. Doing so may damage any attached video card/ eGPU adapter due to a shortcircuit.




2. Attach the second PCIe splitter to one of the male jacks on the first PCIe splitter to create 3xPCIe outputs




Above: 2x6P PCIe splitters attached to a Dell DA-2. Here the user modified one output plug to be a molex, which we won’t do in this topic.


3. Turn on the Dell DA-2 by jumpering REMOTE+GND


Attach a split pin or opened paperclip between the REMOTE and the adjacent GND pin. Then the Dell DA-2 PSU LED will change from STANDBY (orange LED) mode to ACTIVE (green LED).  Examples shown below:


 It is a good idea to apply electrical tape (or at least cellophane tape) around this to hold it in place to prevent any accidental shorting with the nearby 12V pins.


Q: What if I need a 5.5×2.5mm DC barrel connector . . . 

Like used to supply power to AKiTiO Thunder enclosures? Please see this guide on how to create an adapter to attach one of the 6P output leads to. Or use enjoy’s picture reference below:

Hello, I would like to make a new, thinner case for my GTX 1660 (6+2 pin, 110W while gaming). It will be based on AkiTio Node (which I already own). It's powered by 6 pin atx connector and i would like to power it with Dell DA-2 (or similiar, affordable and thin PSU if you can suggest me better option) ask you for a help. From Nando4's guide it looks like all I need to do is to attach PCIe splitter (6+2 F to 6+2 M) to DA-2 and connect REMOTE pin with GND pin on DA-2, right? No more cable management, splitters, etc? Thanks for help
