Your currency tells me you won't be able to buy from Newegg, and prices where you are will be different anyway.
Without knowing what is available, the following quick and dirty rule of thumb should generally prevent you from buying junk: A quality modern PSU has some level of 80+ certification. It's not the efficiency, it's that it was tested at 100% load. Even though they use an unrealistic 23C, cheap junk dies under a test even as simple as that. Seasonic, Antec, XFX, Corsair, FSP, and Enermax/LEPA are among the better brands.
Expect to spend an equivalent of $40-$50 on something reasonable.
