@everyone
sry lots of exams and i come home once a week.
anyway, what big-g said is right. Only industrial customers are charged for reactive power. Industries use lots of induction motors and hence power factor drops. To reduce their electiricity bills, they use shunt capacitors as pfc. Energy Star 4.0 included pfc to improve the domestic consumption and it is not mandatory in india. Unfortunately we cannot buy a psu which meets the requirements of 9800gx2, 3870x2 or 9600gt sli without active pfc. The first 2 require a 8pin and a 6 pin pci-e connector. 620hx, 550vx from corsiar are the cheapest that meet the requirements. Anything higher than 620hx's rating is pretty much useless unless going for quad sli.
I had 1 hour chat with some apc tech support guy. He convinced me that APC uses stepped sine wave approximation and there is no need to worry about active pfc. The problem bullzi is facing is not widespread. I have already talked to people who are using apc backup series with active pfc psus. Cheapest UPS with true sinwave from APC costs 10k. The price is due to high voltage regulation which is useless because psu already does a great job. 620hx takes care of all power problems except power cuts.
ATI Hyderabad recently bought around 180 620HX. I will found out what UPS they are using. Will return after 25 days.
