Power delivery to expansion slots

The following table indicates the maximum current that should be drawn from each expansion
slot. PCI Express slots are limited to 75W in total on the main +12V and +3.3V supplies, all of
which can be drawn from either voltage rail. The total for the riser are for the total current/power
delivered to the riser through the motherboard. If more is required, the riser must draw power
from an additional source such as a separate power connector from the PSU.
