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 (est 2W)
- Soundblaster Model CT4180 card (2W)
- Dual port Intel network card (3-4W)
- Dual port SIIG USB 1.0 card (2W)
- Trident video card (ISA) (3W)
- 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
Stripped down: MB + 128MB RAM + HD = 23 W
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)
