Small Server Room Power

When deploying a small server room one of the first items on the list to consider will be power. Typically in a small server room power consists of an uninterruptible power supply (UPS) and power distribution. While there are multiple types of UPS to select from, the most common types for a small server room will be a Line-Interactive UPS. This is a much different design compared to the stand-by UPS which is frequently used at the desktop level.


With this type of UPS when line power is in operation the inverter/converter will charge the battery, staying ready for a power failure in which it then begins working in reverse supplying short term power from batteries. Based on this design you are able to achieve much faster responses to a power failure. For smaller power requirements of 0.5 kVA to 5 kVA this is the lowest cost and highest reliability for a small server room.

Important Questions

When selecting a UPS it’s important to understand your power requirements and necessary features. A few questions to consider include:

  • What are my power requirements? Voltage & Watts
  • How will you mount this? Rack, Stack or Tower?
  • How many outlets/receptacles do I need?
  • Do I need any specific certifications? UL Listed, Energy Star, etc.

Power Distribution

The other half of the equation is power distribution. In this case you would need to determine if you plan plug your IT equipment directly into the receptacles on the back of the UPS or if you will be adding a power distribution unit (PDU) to your rack and plugging this into your UPS.
