[comp.sys.ibm.pc.misc] Power supply ratings

dd2x+@andrew.cmu.edu (David Eugene Dwiggins) (11/14/90)

I'm tired of all the rediculous talk about monster power supplies.
The fact is, it is simply _NOT TRUE_ that a 100 or 110 watt power supply
cannot satisfactorily power a slim-line 386SX system.
I am using a Quantum 105MB IDE drive, Token Ring Adapter (full length), 3
serial ports, one parallel port, 3.5" floppy, and the power hungry
Wangtek tape drive and controller card.  All this with a 100 watt power supply.
Folks, the new drives don't eat as much power as the ancient full height ones.
My 105Mb drive uses _7_ watts.  The tape drive uses 49.  Does this tell you
what a normal system without a tape drive requires??!!??  I used a Tandy
1000TX with a 67 watt power supply with a 3.5" drive, 5.25" drive, 20Mb hard
card, and four other expansion cards for 2 years with no problems.
Large power supplies are nice... but not required.
