Some examples of a supported configuration with combined power
consumption of 100 W (PCI slots + Universal AGP Pro slot):
1 x 5 W PCI accessory card + 3 x 15 W PCI accessory cards + 0 W empty PCI
slot (adjacent to Universal AGP Pro slot) + 1 x 50 W AGP Pro card
1 x 5 W PCI accessory card + 1 x 15 W PCI accessory card + 2 x 12.5 W PCI

accessory cards + 1 x 25 W AGP standard card
An attempt to draw too much current (such as a short circuit across edge-
connector pins, or an accessory board that is not suitable for this PC
Workstation), will cause the overload protection in the power supply to be
triggered, and will shut down the PC Workstation.
When the PC Workstation is turned off with the power button on the front
panel, the power consumption falls below the low power consumption (refer
to the following table), but is not zero. The special on/off method used by this
PC Workstation extends the lifetime of the power supply. To reach zero
power consumption in "off" mode, either unplug the PC Workstation from the
power outlet or use a power block with a switch.

Power Consumption and Cooling

The power consumption and acoustics (shown in the Environmental
Specifications table) are valid for a standard configuration as shipped (one
processor, 256 MB of memory, 300 W power supply, one hard disk drive,
video card, LAN card).
