430W is good to run?? but i heard from someone that 450W is needed to run gtx 650ti
430w will be fine since you are running a rather weak CPU. nVidia suggests 400w for the 650ti. If you have a more current/powerful CPU, I'd suggest at least 450w, but 430w will be fine for this build. Just know that if you ever upgrade the CPU, you should upgrade the PSU, as well.
