Re: Let's teach Keri how to use an Oscilloscope!
but in the first post you said
so overall it seems to me mobo is the common factor here.
(bad psu perhaps works on lower freequency and is of lower power, BUT that would make ripple more visible...also it's crappy design and caps...)
i would rather use some other load, and then crank up the 'vertical zoom' on the scope(so you can see real small voltage fluctuations).
hell perhaps even just few hdds attached to few molex plugs of the psu.
that should at least give you some idea....(offcourse, if you don't have hdds handy don't buy them just for this)
i should think of something readilly available that can be used to load the psu to at least 200-300w...
i better do some ohm law math and see if i have the resistance i need in any of handy devices...
no, not 12v bulbs, it takes too many of them...
I feel that maybe the low power of this PSU minimized the spikes, or maybe it runs stuff at different frequencies?
Oddly, a really cheap 6 year old pull from an upgrade that weighs about ONE pound came up relatively clean with no motherboard attached, but started spiking all over just like a new Antec EA380 when attached to a motherboard.
