PSU workaround for Dell Optiplex 3050 SFF

[hhvnr12345]

Hi all, I'm looking to get a graphics card, presumably GTX 1060. The only obstacle is, of course, the proprietary PSU. It's using one 6-pin + one 4-pin connect to the motherboard and CPU, respectively.

I know there're no standard PSUs support it, and it seems Dell PSU for these connector rated as 180W at best.

Are there any adapters to convert 24-pin to these 6+4 pin connector? The 24 to 8 pin connector is easy to find on Amazon (only work for Optiplex 3020 though), so I guess such adapter for 6+4 pin does exist, or at least possible to DIY ones? Thanks.

There is a 315W SFF PSU with a 4 pin CPU, and an 8 pin MB, and a 6 pin PCIe ONLY.

If you can DIY an 8pin to 6 pin MB connector you should be good.
I'm not aware of a low profile GTX1060 though? Please post here if you know of one!

Yeah i know that power supply, still only got 8-pin connector though.

There's no Low Profile GTX 1060. The idea here is find an adapter to convert standard PSU (something like... uh... Seasonic 520W S12II?) to the proprietary connector. Since that PSU too big to put inside the case anyway, i can just put the PSU outside, leave the case open and install a normal 1060 (probably a mini one fan 1060, short enough length to put inside).

I have to say that I don't really have the skill to DIY such adapter myself. I'm just asking if such things does exist, or at least can be made.

I'd like to ask though, in case there're no workarounds, the 180W PSU would be enough for the GTX1050 Ti LP, right?

Dell Support said on Reddit that the PCIe 16 slot does provide 75W, which should be enough for 1050Ti without overclock.

Yes the 95W Optiplex CPU limit allows that to work.
I think you're on your own for the 6 pin MB.
If you go back to the Opti 745 era there were 275W PSUs for SFF.
Adapt to 8pin, then make it 6 pin.
Opti 745SFF. Dimension 9200c, and XPS210 were the powerful SFF systems. w/o the 6 pin PCIe.

180W is probably too little headroom.

As i know the 3050 MidTower does have a 240W PSU compare to 180W. There's a great chance they used the same connector. Can anyone confirm it?
