These are the specification that you need to keep in mind when selecting a PSU
- Power Output or Wattage; the max number of wattage the unit is able to output
- Efficiency Rating; the effectiveness of power output and how much is lost to heat as the load its under increases
- The rails; essentially is all the wires that connect to the components of the system, you need to make sure there are
enough rails to connect to all the components in the system. - Protection; what type of voltage protections does the unit supply
- "OVP" - Over Voltage protection
- "UVP" - Under Voltage protection
- "OPP" - Over Power protection
- "SCP" - Short Circuit protection
- "OCP" - Over Current protection
- "OTP" - Over Temperature protection
- "BOP" - Brown Out protection
