Computers

Old blue ATX case

  • Powerman 235W ATX supply with on/off switch
  • Pentium Pro 200 Intel Mars motherboard
  • Four 72 pin 32MB SIMMS = 128 MB
  • No CPU fan (power supply fan directs air directly onto heatsink)
  • Tulip network card
  • Soundblaster Model CT4180 card
  • Dual port Intel network card (3-4W)
  • Dual port SIIG USB 1.0 card (2W)
  • Trident video card (ISA)
  • Intel Mars motherboard PIIX chipset
  • PS/2 keyboard (no difference on power reading w/o keyboard)
  • IDE hard drive: IBM Deskstar 15 GB IBM-DTLA-307015

Boot: 55-60W, peaks to 70W
Idle: 36W
HD spun down: 31W

Spinning down the hard drive saves 5 watts

Power supply has OFF switch; with the various and sundry network cards installed it burns

PS fan and CPU fan died years ago so I put the high quality fan from a Sun 3 workstation into the supply and dumped the CPU fan. CPU does NOT get hot under normal operation.

CDROM drives

Only needed occasionally; I can leave a drive in the system but unhook power to it.

  • Diamond 8X CDROM: 1 W when idle (no disc in drive)
