intel core i3 2100
transcend 16gb ram 1600MHZ
gigabyte z77 series MB
one 2TB WD SATA HDD
one 1TB WD SATA HDD

Yes, that's enough juice for that card in crossfire. However, that model is a Tier 3 PSU and is really not the best option, nor is it recommended, for overclocking or top shelf gaming cards, much less dual cards. Since the chances are good you're in India, this would be a good choice. If you're not in India, let me know what country and I'll recommend a suitable unit.

thank's for quick reply and i am from Bangladesh.

Well, it looks like choices are pretty limited and I don't see anybody listed online for Bangladesh that would be equal to like Flipkart that they have in India. I guess maybe you just have to buy locally but you would know better than me. What you want is a Tier 2B or higher unit from the following list if possible. I'll give you two links. The first is the highly used PSU Tier list. The second is an article on who actually makes the power supplies for most of the major names. For the most part you want a PSU that was made by Seasonic, Superflower or Delta.

There some others that have good models or make them for other brands, but most of the models made by those three companies are generally trustworthy. That's not a guarantee though. Use the Tier list, it's your best friend in picking a unit.

Thank you for tour advice. Should i go for AX860i?? Because corsair is the only brand which is available in our country from the list of tire one psu.

YES! That's a Tier 1 PSU and a pretty good one. If you're limited to only a few brands and models, you're fortunate that's one of them. That unit is actually made by Seasonic so it's a reliable piece of hardware. Very good choice.
