Connecting GeForce 6800Ultra Card to a Power Supply
The GeForce 6800 Ultra requires a stable, 12-volt power source for best performance,
reliability, and enjoyment. For GeForce 6800-based graphics cards, NVIDIA recommends
a power supply with a rating of 350W or higher. To over clock your GeForce 6800 Ultra
for maximum performance, NVIDIA recommends a higher rated power supply.
GeForce 6800 Ultra boards will have two standard disk drive power plugs on the back end
of the card. Both power connectors must be connected for normal use. You may use a
Y-cable or connect two dongles off of the same power cable if plugs are short for normal
use. To overclock, you should attach two independent (not shared or split with a y-cable)
hard disk drive power dongles from the system’s power supply to these plugs.

Figure 2: power configurations for normal use of the GeForce 6800 Ultra (Using 2
dongles off of same power cable).
