    Default dual power supplies?

    I just found a couple of 250w power supplies in my pile o' stuff, and I was wondering how easy would it be to run some things off of one of these, and the rest off of my main power supply? Would i just plug them in and go or do i have to do something?

    You can do that, but you need to splice the green wires together from each PSU in the power bundles that run to the motherboard. Otherwise, the PSU that is not powering the motherboard will not turn on when you press the power button.

    People are stupid; given proper motivation, almost anyone will believe almost anything. Because people are stupid, they will believe a lie because they want to believe it's true, or because they are afraid it might be true. People’s heads are full of knowledge, facts, and beliefs, and most of it is false, yet they think it all true. People are stupid; they can only rarely tell the difference between a lie and the truth, and yet they are confident they can, and so are all the easier to fool.

    wooo... thx my for my old thread resurection

    @andymushu: be very careful with those PSU. Capacitor can keep power for a long time... If you can, dont open the box, just use the external wires.

    You don't want to jump it, that is how you turn a PSU on without having it connected to the motherboard/power button. That way it would always be on, you want them to power on together as one and for that you must splice the green wires together. And of course, as Sly said be careful and don't open them.
