Power supply upgrade for dell optiplex 960.

[PcGamer202]

So i was planning on upgrading my gpu to a gtx 750 ti 2gb.
and as we all know the power supply in the dell optiplex 960 isn't enough to power that gpu:https://www.zotac.com/us/product/graphics_card/gtx-750-ti-2gb-2 .
so i was wondering what kind of psu would be compatible with the optiplex 960. my version is the (MT) the biggest version in the 960 series .
thanks in advance and sorry if it took you long to read.
