A PC uses a switch mode power supply, quite big, taking power in a strange waveform, and this may confuse heavily cheap meters (and not so cheap). Difficult to say.
I think the load on the mains supply is actually pretty straight.
I'm not so sure, but never mind. Se bellow.
A definitive test, in your case, would be to connect a scope on the +5 and +12 rails (perhaps 3.2? line). A spike going down in the +5 would provoke an instant reset.
Hmmm, I could do that, but I've only got a normal scope (no storage), so I'd have to sit and watch it. Maybe.
I'm thinking that the power measured at the input is not important at all. The important figures are the amperage capacity on each of the DC output lines, and that's the power that has to be matched to the load, and where the measurements are important. The AC side is irrelevant, somehow. As to the scope, yes, that would be enough, but of course, you have to be looking at it. Set a slow H speed. Humm... a digital gadget (multiple A/D) connected to another PC would be _very_ nice. They are not so expensive as they were time ago... Argh. I have a good A/D, D/A card, but it is for ISA bus, and MsDOS drivers. Pity! I can not experiment with it in Linux, too late... no hw isa bus. - -- Cheers, Carlos E.
