[gentoo-user] Filthy oscilloscope picture! =P

Isn't this the filthiest oscilloscope u've seen recently?

The only bare metal contact that I could safely use to get a reading off
was a +12v line on a spare PCI-E gpu plug. The ground reference is the
chassis.

You can see the machine's settings in the photo clearly enough. The
waveform is fairly constant, it stays in this mode most of the time but
sometimes goes into a "low ripple" mode where the ripple falls to +/-
20mv and holds tight. The scaling indicates the upward spikes are around
0.120 volts and the downward spikes are about 0.22 volts.  This
__SHOULD__ be within the input tolerances of the motherboard's regulators.

I would call this PSU marginal, it absolutely does power the machine but
it's noise output is a bit larger than what I would prefer.

Given that i'm flat on my ass broke with a foreclosure over my head, I
am powerfully inclined to continue to live with the PSU the way it is
now until it is no longer possible to do so.

I had to use my windows 7 machine to get the photo off my camera because
digikam does not compile. =|
