    I'd run at least a couple fans off your main supply in case your second one fails. Also if you decide to run anything else that also ties in with the main supply in ANY way make SURE you tie the grounds together for both supplies. Ground loops can be a hard thing to diagnose otherwise.

    i don't know that much about psu's so...do you have a diagram or something of that sort to help me out with getting the wiring correct in my head?

    What he's talking about is the basic essential fans, like the cpu fan, at least 1 intake, and 1 exhaust (like the blowhole for example). So if your redundant psu fails, your primary will still run the "essential" fans. Hook up all your other fans and lights to the redundant psu. This will also allow you to turn off the redundant psu (if that is how you configured it) when you are not playing games or pimping your rig to someone, showing them how cool it and you are...

    Making sure the chassis of the redundant psu is grounded to the rest of the system is important as well. If you've got it mounted inside the case (metal to metal contact), it shouldn't be an issue. If you are running it external or seperate from the main rig, you should run a small ground strap from the chassis of the case to your redundant psu. (A small wire with to a couple of solderless connections physically screwed to each chassis.)

    yeah...i understand the basics of what he wants to do and what has been discussed...i'm just curious about the wiring...etc. you keep saying "the green wire" and the like and i'm just not sure which one is which. should i just assume it is a big green wire? and for connecting...can you just solder something like that together and tape it? good enough or does it need something more. thanks, though, for the help!

    <chant for the green wire splicing>

    if your using ATX psu's, the other option is to run a relay, that way you can power it up with BOTH the main psu or the switch and have a useless noise box with lights

    or find an old AT power supply (i have 5 here looking at me right now) and just run it like that
