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 |
4 |
was a +12v line on a spare PCI-E gpu plug. The ground reference is the |
5 |
chassis. |

You can see the machine's settings in the photo clearly enough. The |
8 |
waveform is fairly constant, it stays in this mode most of the time but |
9 |
sometimes goes into a "low ripple" mode where the ripple falls to +/- |
10 |
20mv and holds tight. The scaling indicates the upward spikes are around |
11 |
0.120 volts and the downward spikes are about 0.22 volts. This |
12 |
__SHOULD__ be within the input tolerances of the motherboard's regulators. |

I would call this PSU marginal, it absolutely does power the machine but |
15 |
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 |
18 |
am powerfully inclined to continue to live with the PSU the way it is |
19 |
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 |
22 |
digikam does not compile. =| |
