Evga gtx 260 core 216 supercloked power supply question

the power supply have 2 +12V of 18A and 1 +12V of 19A, is the same that 36Amps?

this card require 2 pci-e of 36Amps.

I really don't understand this
Can somebody help me please?

No, you cannot just add the amperages. On the info card for the PSU it should list a maximum wattage for the two 12V rails combined. What is that for yours?

The maximun wattage for the 3 +12V is 600 watt

Wow, yes that is more than enough. I should have clicked on the link first (from your post I thought you meant it had only a 19A and a 18A rail, which would have been close). So from there, P=IV so Imax combined is 600W/12V or 50amps, plenty for a GTX260. Sorry for the confusion. I hope you enjoy your new card.

You should be fine with that power supply as long as it has the required pci-e power connectors.
750 watt is lots although I would go with a better manufacturer like CORSAIR, PC POWER AND COOLING or ENNERMAX EARTHWATTS.
But that's my 2 cents....still should do the job ok!.....
