*Input voltage restriction
NOTE: The 1125W power supply can also supply 1275W of output power when the input voltage is greater
than 105V. If the input voltage is less than 105V, but greater than 90V for any reason, the maximum power
that can be drawn is 1125W. An uninterruptible power supply (UPS) is highly recommended if 1275W output
power is desired.
The 1125W Power Supply can also supply 1450W of output power when the input voltage is greater than
180V under all conditions.
