The GTX 750ti's minimum power requirement is 300W, your PSU is rated 460W so yes, it will work!

Nvidia's official page says that a GTX 760's minimum power requirement is 500W. I would get a new PSU, from a good brand like Seasonic or Corsair, to be sure that it's a quality PSU.

I did a PSU calculator and I put in all of my specs and it said I was safe, should I trust that or should I call up Dell and ask them?

The thing is, most branded computers such as HP, Acer, Dell, etc. Go cheap wherever they can, and the PSU is something where they really get cheap.

The PSU may have a rating of 460W, but can it really output 460W full load for a long time? You can bet it won't. That's why 80+ Bronze PSU's should be bought when pairing high tech parts, to be sure that it's a reliable PSU.

Oh so would you recommend the Asus GTX 750 Ti 2gb GDDR5 or actully a GTX 660 2gb GDDR5?

I used my OEM 400w PSU with a gtx 670 for a year and a half with no issues and it was even OC'd.

A GTX 760 would be better of course, and the PSU might run it. But the chances of a short circuit are a bit too high. When the PSU goes bad, it may take other components to the death bed aswell.

I'm just placing all the variables on the table.

You can do it other way, get the GTX 760, then a trusted PSU down the road.
