Need This PSU in banglore

[Who]

Okay guys i have a PSU but it's not enough for my system (cause its generic), now i want either corsair VX650 or TX 650 in Bangalore , can you tell me a shop where to buy them ? in Bangalore with address

PS :- if possible would that shop take my old PSU in exchange for a new one (with some discount).

Please reply as soon as possible & thanks in advance.

SP road is it? Golcha IT and Ankit Infotech is what desiibond usually gets his hardware from. Not sure about exchange though.
