    Post AT power supply questions

    Alright, I've noticed that my current power supply doesnt have enough 5.25 power connectors for me. So, my question is this. I opened the case and saw three different connectors running to my mobo, not 2. So, im wondering if there is any difference between a regular AT power supply and the one i have running in this funny intergraph system, what is the other connection? is it optional? Most of all, can I replace it with the AT power supply I've got collecting dust in the basement? is it an AT power supply at all?

    never used one...is there any chance that using too many of these would stress out the power supply and mess it up? I don't fear this too much since this PS is 230 watt but im sure it could happen. I think I will do that. Anyway, I'm still curious as to what the hell kind of PS it is. I am almost sure it is AT with how the switch works and that two of the connections going to the mobo are just like AT (P8 and P9 with the blacks in the middle). This is one of the strangest machines I have ever worked on, but its solid as a rock. All I have to say is SCSI is weird yet cool. :-)

    you could overload the psu but you would need to have lots of drives

    230 w psu is enough power for most systems

    ive only got a 200w in my miditower and im running 2 hdds 2 cdroms 2 floppys and 3 fans

    Any chance of a picture?

    I have a stack of old compaq power supplies wich outwardly look like AT but are actaully quite different as they have extra connections for 3.3V. Maybe you have something similar.
