Sorry for the late reply, I was at LWCE running a booth last week...

How did you do these measurements? The only thing that I've been able
to do on my systems is grab a clamp-on amp-meter on the line going to
the PSU, and do the math from there. I'd -love- to get some real
numbers for my systems.

Any suggestions on a brand to buy? I think I'm in need of a different
PSU, but I haven't figured out how to check, and didn't want to shell
out the money for a bigger PSU if it wasn't going to fix anything.
