If the TX version you are referring here is the version 2 one, confirm positiviely before jumping in, then i would say to go for the Corsair TX one,750 is a huge huge overkill, your system wouldn't even extract 350w of power and 750 at 85% efficiency is almost double, i would say 650w is the range you should go for, and save the extra cash.
Now do confirm that the TX unit is the revised version that is v2 as the earlier versions are not recommended at any cost, i got into a huge fight with Lynx dealer Amarbir for this itself, so it's a complete and utter NO to the earlier versions of Corsair units.
If they are the revised one's grab the 650w, since 750w is just plain foolishness considering the rig you are going for.
I just got the Antec unit for 6500/- without any bargain, i was quoted 6200 including shipping and with 5% taxes the total coame out to be 6500. Mr. Vitrag bhandari i suppose was the person I talked to and they shipped it through Blue dart AIR and i got the unit within 2 days flat. So either you have been talking to the wrong guy, or the wrong distributors, u can try mailing at
info@hdigitallifestyle.com and try again.
As I said earlier Seasnic makes the PSU's for a lot of companies including Antec, Corsair and many many more, So you really can't go wrong with a Seasonic unit but the wattage you are going for is a huge overkill. I haven't looked at the Seasonic 650w SS, i even't don't know if they make one, but if it's like it's older brother in all respects then i would suggest getting the 650 one, or even try looking if 550w is available and what are the reviews for it. will save you money because with the config you are telling me even 650w is an overkill (unless you are thinking of going Sli or Xfire) I would say go for the lower power rating unit and invest the money on another GPU, would give you one hell of a rig, 500 - 550w unit should be the ideal one for you if you don't plan on going SLI or Xfire.
