    I thought that we were talking about P3 systems here? The big draw should be on the +3.3V rail, no?

    I that a Thermaltake supply made during the P4 era for a huge gamer tower with over 50A on the 5V side.
    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

    AFAIK no, the VRMs are driven by the +5V rail

    Anyway the 250W supply works with the dual 1.26ghz P3s, 2 tape drives, and 1 IDE drive but a second HD trips the supply.

    I figured it would. It works for my dual P3 system. Uses a SSD instead of a hard disk, however.
