Rép. : Re: [K12OSN] alternative power supply

Fri Dec 3 01:57:40 UTC 2004

I modified a ATX power supply for my laptop. My laptop required a 12V 5A
P.S. when everything (floppy, cdrom, sound to the max...)was on. Since
this requirement was very low compared to what it could give i installed
a dummy load (Power resistor) just to keep the switching circuit happy
with a load when the laptop wasnt hooked on. I also reduced
significantly the noise level by hooking up the internal fan (12V) onto
the 5V output. Everything is working great for several months now
(24/7).

WRONG (grin). My original question was, essentially:
Has anyone stripped out the original power supply of old "junker"
PCs to realise the same noise and power saving of specialised 
thin-client hardware?? 

Other postings so far have suggested measuring the current draw of
existing power supplies in PCs using an inductive clamp meter.  This
is
something I have and I can do that sometime soon.  

I guess I was asking the group what they thought of my intended
approach
and to find out if someone had already been down the same path.  If
that's not the case then I will embark on my adventure soon and then
report back my results.  Unfortunately, I don't have any LCD monitors,
but the power savings of these over CRT monitors is pretty
self-evident.
