Reference GTX750 ti has a MAX TDP 60W and needs 350W minimun :http://www.realhardtechx.com/index_archivos/Page362.htm , so EVGA SC maybe from 70w to 80W more or less , so almost any PSU from 350W should work. However that PSU looks really crapy and has old ATX config(more amps at +5V than +12v rails), so I recommend you a good branded certified PSU like new CX450M series from Corsair for instance (not the best but much much better).
The PSUs +12v rail is very important when taking about GPUs, but in PSUs all internal topology is really important as well(the better the PSU the safer the GPU)
