Shame about WOL, I really miss that feature.

600 watts would be a little ridiculous for a modem and router, you want to take the voltage output of the PSU and multiply it with the amperage output of the PSU.
In this case its 12v x 2.5a = 30w max or x 1a for 12w.
The PSU itself of course can still be and most definitely is pulling more power from the wall than it is outputting due to inefficiencies I honestly have no idea about the efficiency of this type of power supply but would use 80% efficient as a general rule.
So adding another 20% on I get somewhere south of 36w for router mode and 14w for modem mode pulled from the wall. This of course also depends on how much work the device is doing and would be absolute maximums.
Your amperage x 240v is correct for anything that takes 240v directly (although the target voltage in the UK is 230v).
