Power Macintosh G3: Maximum Wattage Used By PCI Cards

This article provides the electrical specifications for four of the cards currently offered through the Build To Order (BTO) web page.
Following are the electrical specifications for four of the cards currently offered through BTO:
.
Card
Maximum Wattage
Ultra Wide SCSI card
10 watts maximum
128-bit 2D/3D graphics accelerator card
8.925 watts maximum
Firewire card
10 watts maximum (1)
10/100 Ethernet card
6 watts maximum
Notes
(1) With all three ports of the firewire card in use, the card uses approximately 1 watt. However, since the firewire specification allows the card to provide "bus power" to connected devices which don't provide their own power, and the card is fused at a maximum of .75 amps (at 12v), that adds another possible 9 watts, for a maximum of 10 watts.
