Remote and ground of the DA-2 itself have to be connected to keep the DA-2 on.

Guess you need to find a forum that can help you how the Pico works.

Ok... I think since you would normally use "stupid" PSUs with that Pico, the Pico handles the powering on process itself. So the Dell DA-2 would have to be turned on in a different way before the Pico can use it.

So try and make an electrical contact between the remote and any ground pin on the DA-2 plug. After that the Pico should be powered and work with the power on signal from the PC.

Uff... Since the PC only gives a short contact, when you actually press the button you would have to turn that impuls into a permanent closed connection for the DA-2.

You could install an indepentend switch for the DA-2, but I have to clue if that would make your PC boot?! Not sure if the PC MB needs the signal to boot.

Ok, the remote pin does need to have a permanent closed circuit to turn on the Dell DA-2 (to ground). So you need to figure out how your switch works. If it only give a short contact the Dell DA-2 does not stay on.

Not sure if you have the Dell DA-2 we are talking about here. Does it have the 8-Pin plug? How did you connect it to the Pico?

@BTAWhich Pico did you get?

@g-hood Yes, it is possible!

Currently AKiTiO onl realeased the Thunder3 in a bundle with a 900$ SSD....

The Thunder3 itself isn't released yet. So there are no confirmations about the Thunder3, but I am optimistic that it will work.

Any GTX900 card should work in OSX thanks to a script from this forum.

What is your goal? Is an external display an option?

I hope he does it with the EVGA 750W PSU, because you should power the whole system with a single PSU.

Please read this basic guide:

Someone is selling it for 648 on ebay with a 300w power supply and a 0.5m thunderbolt cable? Will that be a good option? (No GPU installed)

P.S. any idea if this would be compatible with the new 1080 and 1070?

Imho, that is VERY expensive!

You can't use the power button on the case. Only with an adapter called "SWEX". But they are somehow very rare...

I think the Thunder3 hasn't been released yet.

This is the Thunder3 but packed with a 1.2TB Intel 750 Series PCIe Gen3 x4 SSD. With that SSD the price for the bundle will be around 800-1000$. Of cource you can sell the SSD

I think sound is not working through HDMI on eGPUs. Better ask goalque in his script thread.

1070 should work, but 1080 might be tricky.
 Let's see what official benchmark will tell us about power consumption.

You can do it in 2 ways:

1. Get two splitter cables with 6-pin to 2x6-pin. Plug the first into the DA-2, connect the 2nd to the 1st and use the barrel plug with the any of the 3 resulting 6-pins. Means: cut of one of the 6-pin plugs, remove 5mm of isolation on them and plug them into the barrel plug.

2. Get an 8-pin extension, and rewire them (soldering) to match the official 8-pin PCIe pinout. Add some cables during the process and get 12V and ground for the barrel plug.

@leendert Yeah, looks perfect.

The most knowledge can be found here: https://www.techinferno.com/index.php?/forums/topic/7377-220w-dell-da-2-ac-adapter-discussion/

There you can see the pinout of the DA-2 and that you need to switch some 12V and ground cables to match with the regular PCIe plugs.

You would need:

- a 8-pin PCIe extension female to male

- a barrel plug (with some wire)

- a 6-pin y-cable

With that you can rewire the 8-pin extension and plug the 6-pin y-cable into the 8-pin. The 8-pin extension has to be rewired and the barrel plug added.

Imho that is just interesting as a demo, because I can only see eGPUs making sense with laptops.

Why get a small desktop PC and a eGPU?

Uhhhh.. I don't really have an idea what that is. Wasn't the main problem, that MacBook with a dGPU do not have enough recources to add an additional GPU? Guess the best way would be do deactivate the dGPU. Still... jsut a guess

You need an external monitor!

If you need a soldered adapter? PM me

well... you must be aware that the GPU will be too long to fit into the AKiTiO. So you will have to cut/bend the case or use a riser cable and relocate the GPU.

To make the PSU start you will have to apply the paperclip trick or buy an adapter like this: https://www.caseking.de/ek-water-blocks-24-pin-atx-ueberbrueckungsstecker-waek-1226.html
