    Power Supply wire color code?

    Is there a certain code to the wires that come out of ATX/AT power supplies? I know that on a molex connector its

    Y B B R
    12 Gnd Gnd 5

    But what about on the attachment to the motherboard? Here's why I'm asking: I bought a character LCD that needs -5v on top of 5 and Gnd. I was told to just splice it into the white wire on an ATX connection and that it will supply my -5v. However, on my box im using for my setup I've got a funny power supply. Its connector is neither standard AT or ATX. Reading the label tells me that it supplies -5v at 0.1a, this should be fine for my setup. But should I assume that the white wire is my -5? Before you ask, No. I do not have a DMM at my house. I've googled my *** off trying to find out more about my supply (Delta Electronics Model: DPS-100TB-3 A) and have found nothing. Is white the standard -5v connection on power supplies?

    check sproggy's documents, particularly the doc of v2.6 power supply. It shows the color code and voltages for the ATX plugs

    And you say people actually pay money for M$ Windows? (Does what it says on the URL) (The new car, with zero rust!) (My other site)
    Total re-design underway: on the whole progress is very slow as the car is taking up too much time :)
