Dell Optiplex 3070 SFF PSU and GPU upgrade

Question

Hi, I was wondering if it is possible to upgrade the GPU in my Dell Optiplex 3070 SSF. I would like to try and put a GeForce GTX 1660 inside of it. To do this I would have to upgrade the PSU. Would the Optiplex even fit a 1660? And if so what PSU can I upgrade to to allow the power that the 1660 requires.

Thanks,

You would be hard pressed to find any SFF psu that provides 8 pin power connector required by 1660. This means to install 1660 you have to install a 450W psu outside case, not elegant. You also need a 24 to 6 pin adapter for 3070 motherboard. Once you install psu out of case, you may install a double slot short gpu in case. but for SFF you need a low profile card, which is difficult to find in 1660.

1660 is a 120W-130W video card that generates good amount of heat for closed SFF case. You might as well leave case open to help facilitate heat dissipate.
