Convention Power indicator pattern Condition CAUTION: AC power supplies support both 220 V and 110 V input voltages with the exception of Titanium power supplies, which support only 220 V. When two identical power supplies receive different input voltages, they can output different wattages, and trigger a mismatch. CAUTION: If two power supplies are used, they must be of the same type and have the same maximum output power.
