Condition
CAUTION: AC PSUs support both 220 V and 110 V input
voltages with the exception of Titanium PSUs, which support
only 220 V. When two identical PSUs receive different input
voltages, they can output different wattages, and trigger a
mismatch.
CAUTION: If two PSUs are used, they must be of the same type
and have the same maximum output power.
CAUTION: Combining AC and DC PSUs is not supported and
triggers a mismatch.
