Rép. : Re: [K12OSN] alternative power supply



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.
