*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.
