| 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. |
E | Not lit | Power is not connected. |
