    Default Need information on an old DELTA AT type supply OEM IBM

    I have a Delta Electronics DPS-145PB-72 A rev 01
    IBM P/N 76h4855
    FRU 76h4856
    EC E71692

    150W

    It has 3 of the AT type power connectors for the motherboard and no on/off switch (unless a small 3 wire motherboard plug is the on/off).
    What I collect: 68K/Early PPC Mac, DOS/Win 3.1 era machines, Amiga/ST, C64/128
    Nubus/ISA/VLB/MCA/EISA cards of all types
    Boxed apps and games for the above systems
    Analog video capture cards/software and complete systems

    It sounds like some of the older HP Delta PSUs that I have with the 3-pin fan speed cable.

    Reminds me of the supply I seen in an IBM dual PPro desktop where 2 power leads went to the motherboard and one to the riser card complex (before they all went to ATX supplies i guess).
