*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.
