  1. All 3 of those cards will work on a decent quality 300W PSU. So list the specs for the 240W PSU. My 240W Dell PSU handles my 60W 1050 Ti just fine, but some 240W PSUs have too small of a +12V rail.

    Wait! That isn't one of those laptop-like bricks powering the PC, is it? If so, the answer is NO.

    yes it has one of those laptop like bricks powering the pc; what do you recommend that I do? gpu wise because the gtx 645 isn't keeping up with the latest games?

  3. Wait... Something isn't right here. (Probably me :pt1cable:) It came equipped with a (130W) GTX 645? If so, then the (60W) GTX 1050 Ti should be fine. Is this the PSU you have?

    If your PC came from the factory with a GTX 645 in it, there's no reason it won't work with the GTX 1050 Ti. But I'm stumped as to how it is doing it on that small brick, tho.
