Point to note. if your equipment is plugged in, nothing is going to stop a lightning strike over 500kV and 10kA going thru the small switching at the socket. Everytime you turn off the power supply, the system discharges and starts draining your internal CMOS backup battery, then you will find that you need to replace the battery every 6 mths or so. And everytime you turn on, there will be a surge of power to charge the empty capacitors in the power supply, reducing the lifespan. So you want to switch off still? Go green, leave them on, switching them off does more damage to your equipment.
