I purchased an Inspiron I3670-5750BLK-PUS without realizing that the power supply did not have any spare wires on it for extra components. I would like to add a graphics card to the PC, but as the power supply does not have any extra wires, this is not currently possible. Are there any options to upgrade this proprietary PSU? It looks like a standard ATX power supply will not work as the power connector on the motherboard is an 8 pin rather then the standard 24 pin. There is also a 4 pin on the opposite side of the board.
The other option with a 3670 is the 365W power supply that supports OEM GTX 1060.
When installing an after-market graphics card into a Windows PC with UEFI secure boot enabled, the system may not boot. This is true for ANY PC not just Dell.
Hi, I'm in the same position, trying to use my GTX 970, but can't power it. Did that cable work? Another issue is the card can fit (barely), but the 8 pin connector on the mobo is right under the video card, and am unsure if the card is fully seated in the slot, so a low profile connector, or perhaps a right angle connector might help out. Did you have this issue?
The cable adapter I posted in my original post worked fine.
I haven't gotten around to buying a video card yet, so I can't comment on this. I'm planning on buying a short single fan model though to keep it as compact as possible to avoid any issues with fitment.
I did have to hack out a bit of the back of the case though to allow he power cord connect to clear and fit. I guess I should have paid more attention to what I was getting. Oh well...
I'm looking to upgrade the PSU myself. I noticed the Dell OEM PSU has the fan facing directly to the rear (plug side) and the new PSU, including the Corsair 550 watt you installed has the fan facing the side. It appears that after it is placed in the case and installed, the fan will be facing to a flat side of the case (no vents). If this is the case with your install, have you noticed any more noise or heat issues? Just curious how your install is working out.

I'm trying to do the same thing to my i3670 DT, and also realized, after buying a EVGA 600W PS, that the fan in the PS faces the case bottom, and there are no other venting so I would think the PS might overheat.
Also, the EVGA PS AC input did not quite line up with the cut-out on the back of the case.
I did buy one of the 24-pin to 8-pin Dell PS adapters, but have not been able to try it since I haven't found a PS that fits.
A little notch on back by recptical, an cut a vent into bottom plus adapter shown above you can do it by repining an adding 12v. I tried this after looking up the moddiy an i did have machine running. only reason i used other adapter cause I already bought it plus it was a rats nest after i got it going
Yes fan is facing down. Had to notch out right around the plug not very much maybe 1/8 inch. Also cut an made vent at the bottom under the fan for ventilation.
That is an interesting mod. I bought the 3670 based on the overall spec but there was no option to upgrade the video at time of purchase. I thought I have a FreeSync monitor which requires an AMD card to get the freesync to work. Which means that even the Dell 365w PSU will not be enough to drive it. So I would need to do the mod you did to get an aftermarket psu to work..
I don’t know how much modding you had to do to get the PSU to fit. What was that board with the wires soldered on? Is that part of the mod? And you need a 24 to 8pin adapter. Correct?
In addition I assume that is the sapphire short GTX1060 card installed? I need to know how much more length is available in the case. I believe the sapphire card is 7.2 inches. I found an RX 570 CARD (gigabyte AORUS) that is 9.1 inches. Do you think there is room.? My system has not arrived yet and I want to get the parts ordered so appreciate your input.

It might work. The CAB359 from Moddiy has been tested and works fine.
Optiplex 3020 9020, Precision T1700, Power Edge T20 also use the same thing.
There is also a guy who made his own adapter from scratch.

Let us know how it goes.

The internal parts page shows 290w standard 365w optional.
Full Length GTX 1060 does not physically fit into the case.
But the following Dell OEM full height but short video cards work with Dell OEM 365w PSU =
