Dell Optiplex Upgrade 1050 TI LP Will it Work?

If you plan to add discrete graphics card, try to select a tower as it can accommodate double slot cards.  The 1050 ti may not fit small form factor due to the graphics PCIe x16 slot is too close to power supply.  Restricting to single slot cards only.

Power wise, PCIe x16 in tower will provide 75w while PCIe x16 slot in SFF gives you 50w.  Users also use PCIe x4 slot with 25w power to drive higher wattages but that will be at your own risk.

this user installed a 1650 LP in 7050 sff.  looks great and performs great

"the psu is 300w so it's enough for the 1650"

While the above user put a 300w PSU in a 7050 SFF, they normally only come with a 180w PSU.  This is why a 75w card is outside of Dell specs.  This is unless the PSU is replaced with a 300w one like the one above.  75w cards can get away on a PSU with a few less watts, but not 180w.  That's too much of a risk.

Few cards will work with a 180w PSU:

1. 30w GT 1030 GDDR5
2. 20w NVS 310
3. 20w GT 710
4. 19w GT 720

From the 7050 spec sheet that I'm also attaching (the middle column is for the SFF):

The spec sheet may also list a couple of compatible cards for the SFF.
