Hey all,
A few power supply ramblings.
Received a picoPSU-120-WI-32 from www.mini-box.com. Put it on my
homebrew power supply tester, which is really nothing more than a bunch
of resistors stuffed into a power supply case. (I used to do some
computer repair and it diagnosed many flakey PS's.)
Applied the following loads simultaneously while powering the unit from
a large 12 VDC gel cell:
+3.3 volts, 5.5 amps
+5 volts, 5.0 amps
+5 volts Stand By, 1 amp
+12 volts, 5.2 amps
That's 110 watts of load - it's rated for a maximum of 120 watts. The
little thing had voltages all within specification. The lowest was the
+12, which was 11.5 volts.
I'm impressed. The psu does warm up after a minute or so at this power
level and I only ran the test for a few minutes.
One thing worth noting - the little guy has no -5 VDC output...
I didn't check for RF hash, etc...

Thanks and 73,
