i had an hd 5570 card which did not require an external power supply which got damaged so they replaced it with an xfx hd 5770 which requires an power supply , when i just inserted the hd 5770 card in the pci -e slot wihout connecting the 6 pin connector the card fan spins but no output is displayed , so is the card defective again or i should get an newer corsair power supply and try ?

If the card has a 6-pin connector, then yes,it needs that to be hooked up in order to function properly. Usually, they come with a molex to PCI/E adapter cable for those PSUs that do not have a dedicated PCI/E connector.

Yes, having only 240 watts is also an issue(AMD recommends 450w)! You should be happy with the Corsair. It is one of the better reviewd PSU's

You don't need the 6 pin connector, cards come with a molex adaptor, however you can't use a 240w psu.

Corsair does not make psu's and CX is their cheapo model, kinda like the C-class Mercedes, however it's still decent. Hope this helps.
