15. Tips & Notes
• As already mentioned, the power supply unit is in "standby" mode once you have switched it off
via the power button of your ATX housing.
This means it is not separated from the mains voltage! A television, for example, works similarly,
where you can switch it to "standby" mode with the remote control.
The ATX power supply unit still "uses" electricity in this "standby" mode. This is why you should
also switch the ATX power supply unit off via the mains switch in order to save energy, if you don't
need your computer.
Of course, the same is also the case for all other devices that are connected to the computer, eg
monitor, scanner, speakers etc.
Devices without a "real" mains switch (eg many computer speakers, some monitors or also all
other devices with plug-in power supply) can be separated from the mains voltage via a multiple
socket with on/off switch.

The standby power consumption of a complete computer system can easily reach 50W.
After only one day one kilowatt-hour (1 kWh) was wasted and transformed into heat.
This is why the purchase of a multiple socket with on/off switch already pays off after one year.

The joint switching on of all loads (computer, monitor, printer etc.) may trigger the circuit
breaker of the corresponding electrical circuit, since the switch-on current is too high.
If this happens to you, first of all switch on the switch of the multiple socket and afterwards in
successive order the individual devices.
When you are switch off, you do it the other way around, first you switch off the devices and
afterwards the multiple socket.
There are also so called "power mangers" that comfortably allow to switch individual sockets on/
off on the front via switches. Such "power manager" can be placed, eg under the monitor.

Ink jet printers have to be switched off via the on/off switch on the printer first, before the
mains voltage can be turned off via, eg the multiple socket.
Otherwise the printer is not able to put the printer head into the home position, the nozzles
of the printer head could dry out!
Some types of printers should be permanently connected to the mains voltage otherwise
they would carry out an additional cleaning process (when the multiple socket is switched
on) when they are reconnected to the mains voltage. The costs for useless ink
consumption exceeds the savings for electricity.
• If your mainboard has a 4-pin ATX2.0 connection for the +12V voltage (can be found on, eg almost
all mainboard for Intel P4 or AMD64 CPU), then you connect it with the corresponding connection
of the ATX power supply unit (see chapter 14. d) and e).
The connection serves for a better supply of the on/off controller on the mainboard (which creates
the electricity or the voltage for the CPU) and for a relief of the +12V line of the ATX mains plug.
If the plug is not connected the mainboard may not start.
