_AkasH_ @ I appreciate your suggestion.. but you are late buddy.
i have already bought iball 621 v ...
gets decent 20 minutes backup .
I am planning to get a Corsair CX430v2 , this ups is gonna be issue then !! I know...
All I need is 5 minutes of backup... there are usually 5-1- blackout every week here... and it has only a life span on less than 1 minute... So with a cheaper UPS I will be ok for now*
