I have a power supply with 305 W and 18A on dual rail. It is written like this 12VA=18A max and 12VB=18A Max. And I have a mini tower of dell optiplex 755. I wanted to ask will HD 6770, 5770 and Nvidia GTS 450 work on my power supply. And there is one thing that I can't understand is shown in this pic (http://imgur.com/tFYvMrR) I can't understand the 25W thing. Thanks in advance.
Can you tell me the card equivalent to them, see the reason is I want to play watch dogs on low settings and I want a card that can play that game on low settings, and can you plz suggest a card that does not require a 6 pin connector.
That's gonna be tough. I would say a 5750 or a 6750 but those both require 6 pin power connections, so again you would probably need to find a 6 pin to molex adapter for it to work with a dell optiplex PS. Its a shame you can't find a 7750
