The Ap2-6300 ordered differently than most power supplys at the back a AC power socket, those that attach a monitor made possible. Since itself the ATX standard established does many (most) manufacturers without this useful addition. The disadvantage on the renouncement of this socket is clearly obvious. The monitor must be switched off separately and consumed in the possible Standby enterprise still rather much achievement. With this connection the problem can be gone around. The moreover still another rocker switch finds around the PC from electricity mains to to completely separate on the back.
