Having problems with your PC Desktops ?

I need the color codes, and more importantly, the polarities of the tips that come with universal notebook power supplies. Thanks for any help.


Answers :

Depends on the brands you are looking at.

(numbers expressed as V)
Blue -12
Red +5
Orange +3.3
Grey Power good signal
Green Power switch
Purple Stand by power
White -5
Black Ground
Yellow +12
Connected with newer psu as per color/voltage details even white -5v but system is not getting on any technician can help me
