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.

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
