• Max is the maximum that can be expected with the default configurations listed above.
• Fully Loaded Max is the maximum that can be expected when the computer is fully loaded with PCI cards, memory, and hard drives.
• Power numbers are input power to the AC, not output power. These numbers were derived from these considerations:
  240 W for processor and DC-DC
  10 W for optical drive
  15 W for hard drive
  25 W for graphics card
  20 W for main logic board
  80% efficiency
