Attention: To get the best performance from the NVIDIA Quardro FX 1000,
NVIDIA Quadro FX 1100, and NVIDIA Quadro FX 3000 video adapters, you must
connect the video adapter to the computer power supply. Otherwise, the video
adapter will be operating with very limited power, resulting in a decrease in
performance for some applications. You will need to use one of the disk drive power
drops to connect the video adapter to the computer power supply. This means that
when you install this video adapter in your computer, you have one less power drop
for optional internal devices. The following illustration shows the location of the
video adapter power connector:
Models with the NVIDIA Quadro NVS 280 or NVIDIA Quadro4 580XGL video
adapter come with a low force helical-60 (LFH-60) to dual-analog monitor pigtail
cable. If you want to set up two digital monitors, you will need to purchase a
separate dual-digital monitor cable.
