You're welcome and no problem. You might be stuck with having to go to the lower card unless you buy another power supply. You might be able to run a gtx 750, not the ti, as it doesn't need a 6 pin and 300 watts is recommended but it is a pretty low power card if the rest of your system is not drawing too much power but it would be a chance you'd have to take.
EDIT: What is the rest of your system and I don't know indonesian prices for the 750 either, so it may be too expensive.
