Y PSU is iball lps223-400 will it be compatible and what price in Indian rupees?
That is a horrible power supply, even the 750 Ti I would not risk running on that PSU.
Spend a bit on a different power supply, even the Antec VP or the Corsiar CS or CX models are better, about a 400 watt PSU, and get the 750 Ti. This also depends on your case also, did you check to see if the cards will fit inside your system?
