  1. It's a crappy psu, but for a 7750 it will do, the 7750 doesn't require pcie 6 pin power from the psu, only from the pcie slot of the mobo(75w).
    Maximum load of the card is about ~50w.
  2. Best answer
    should be fine, but in the future id upgrade that ps, since a noname brand crappy psu will kill a system in the future or at best run it unstable.

    for 60$ its worth investing in a ps of quality such as :

    ;) stability and peace of mind def worth it
  3. ya i have to upgrade my psu in future, this one powers my nvidia gt 430 at present.
