The CTR has got it's own PSU, the PPPoE ADSL modem has got it's own power supply too and they were connected before I added new hardware, but I additionally connected my old parallel port HP DeskJet 600 with it's own power supply and it's turned of when booting. I still suspect that for the boot process the 450W/230V<2A PSU is to weak. I suspect when measuring the current consumption at the mains side of the PSU, everything would be ok. I suspect that behind the voltage stabilisers there might be an issue sometimes. I wonder if there's a monitoring or if there's a way to turn of power at boot automatically for e.g. USB and to turn it on near the end of the startup. I read something about wakeup, but without explanation, since I guess a wakeup is doing something different. Because it only happens sometimes, i can't just disconnect one hardware after the other to make tests. But you're right, I'm not sure if the PSU is simply to weak, might be something else.
