A good source of 5 and 12 power supplies

I was just fooling around with an old discarded PC when it occurred to me
that these clunkers have a wonderful compact switching power supply (SPS)
fan and all. I checked 2 PCs. The 220 Watt one can produce 8 amps at +12V
and a wapping 23 amps at +5V while the other 145 Watt supply produced about
half that!

2 or 3 would make a fantastic Rife-Bare (RB) power supply when coupled
(matched) properly, the small size of switching supplies is another bonus.
In my case this just made it about 30+% cheaper to make a RB device

I have seen so many old discarded PCs - now I wish I would have picked them
up. Even a new PC case, which includes the SPS, is only about $50 Cdn. But
old ones are all around.

Just imagine what one could do with these little beasties. BTW like many
sophisticated power supplies they to require a load to operate.
