Tangent: it's a personal pet peeve that Model M buckling-spring keyboards often pull too much power for modern PCs. This is particularly apparent with the PS/2-to-USB adapters but also happens with some PCs using "native" PS/2 connection. And then I got a fancy Unicomp Model M with native USB connection and... that does it too.
That was on a Dell desktop I had at a previous job. Not sure if it was just kinda crappy, or whether the inrush current on those Model Ms is just that big.
