Power supply unit problems

1. Ensure that no loose connections exist.
   For example, loose power cables.
2. Ensure that the AC power source is properly connected to the PSU.

   NOTE: If the 2000 W PSU or 1600 W PSU is installed, ensure that it is connected to a 220 V AC power source.

3. Ensure that the power supply unit (PSU) handle or LED indicates that the PSU is working properly.
   For more information about PSU indicators, see the Power indicator codes section.
4. If you have recently upgraded your system, ensure that the PSU has enough power to support the new system.
5. If you have a redundant PSU configuration, ensure that both the PSUs are of the same type and wattage.
   You may have to upgrade to a higher wattage PSU.
6. Ensure that you use only PSUs with the Extended Power Performance (EPP) label on the back.
7. Reseat the PSU.

   NOTE: After installing a PSU, allow several seconds for the system to recognize the PSU and determine if it is working properly.

   If the problem persists, see the Getting help section.
