275 watt power supply enough for 750 ti?

Solution
Your 750ti probably requires supplemental power connection. That power supply won't have any. You need to verify if the specific card you are looking at requires supplemental power.

I cant see a 6 pin connector on the PCB of that card however i couldnt find enough info on the internet to confirm that this card does not have a 6 pin connector. You might want to give the seller a call and confirm it from him.
