Question Will a GTX 1070 work in an Optiplex 1070?

Jan 28, 2020
Hello guys!

I own an Optiplex 790 i5-2400 and I wanted to upgrade it with a new GPU. I live in the caribbean so ordering parts on amazon is not particularly easy nor cheap.

Be that as it may, recently I was being sold a brand new GTX 1070 windforce 8gb for too low, so I was thinking of getting it.

My questions are:

Will it fit my computer? if not, is there a workaround?

Do I have to buy any additional parts? like a PSU?

Take into account that going for a 'cheaper' option like the gtx 1050ti is quite difficult considering that I'd have to either import it or finding it very costly.

The price that they gave me for the 1070 is 150$, while here (Venezuela) a 1060 elsewhere could cost around 350$
