peet1234 0 Posted September 2, 2014 Hi, I have to install a q-see system at my work. So my boss gave me all the things but didn't have the power supply(for the power tail) coming with it.. so i guessed he bought a used system from some guy. So my question is: what is the power rate for the power supply that i need to purchase? I know it is 12 V but i'm not sure about amp it needs. I got an 12V 1.25 A output power supply at home would it work?? Oh and sorry for my english, it is not my first language Thank you for your answers! Share this post Link to post Share on other sites
