Galaxy GeForce GT 440 2 GB DDR3 work on ASUS P5QPL-AM ???

If it has the PCIe slot then yes.

ya it has pci e slot; but how about power requirement and memory clock spec's ; can my mother board and graphics card work well; any prblm??? i dont know the tecnical words ; but any opinion from ur side...

I have never heard that PSU brand in my life. You may want to get a 500 watt brand name one, as a fried computer is more expensive to upgrade.

Edit: http://www.kunhar.com/vipcabinets/downloads/smps-compar... according to this chart that only has 9 amps on the 12 volt rail. It won't power any discrete graphics card, as it's prob struggling just powering what you have now. ALSO it says on that chart it has only 246 watts.

its not zeebronics; its zebronics  

Popular in India and other such markets. That and Iball.

I'm assuming you are asking about your motherboard and the card because they use different types of ram. As I said earlier, you'll be fine. What happens on the card doesn't matter. Its on the card, the motherboard doesn't see it. Its ok that one is DDR2 while the other is DDR3. My own system uses DDR3 and GDDR5. It works fine.
