As my system config. is my sig., i won't repeat it anymore. To say the least that I was a little miser in spending over a PSU and currently, I am having problems during playing of heavy games like Q4 or NFS:MW, when the nvidia pop-up comes notifying that my graphics card isn't receiving sufficient power supply and has been down-clocked to safe it. So, I have been thinking of getting a good PSU (don't yell @ me when I say that I have been using a Frontech 450 W PSU with my config). Please suggest me a good price-to-performance ratio PSU which satisfies my config. I would expect the prices to be on the lower side but the performance should be rock-solid and stable. Better if the prices are in Kolkata.
