CAUTION: AC PSUs support both 240 V and 120 V input voltages with the exception of
Titanium PSUs, which support only 240 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.
