SC812L Chassis Manual
4-12
Depending on your chassis model the SC812L Chassis has a 280, 410, 420, or 520
watt power supply. This power supply is auto-switching capable. This enables it to
automatically sense and operate at a 100v to 240v input voltage.
New units can be ordered directly from Supermicro (see contact information in the
Preface).
