SuperOverclockSeries Graphics Accelerator
The GV-N275SO-18I/GV-N26SO-896I graphics card is a performance optimized high-end card. Power
is taken from the PCI Express host bus as well as the two 6-pin PCI Express power connectors.
If you want to use the included 6-pin power adapters, make sure at least 12V/15A current is
supplied to each 4-pin power connector on the adapters. Failure to do so may jeopardize the
stability of the graphics card.

metal cover from this slot; then align your graphics card with
the PCI Express x16 slot, and press it in firmly until the card is
fully seated.
Step 2.
Replace the screw to fasten the card in place, and replace the
computer cover.
Makesurethatthegoldedgeconnectorofthegraphicscardissecurely
inserted.
Step 3.
Plug the display cable into your card; then turn on the computer
and monitor. To connect a D-Sub monitor to your graphics card,
use the D-Sub connector. To connect a flat panel display to your
graphics card, use the DVI-I connector. To connect an HDMI
monitor to your graphics card, use the HDMI connector.

How NVIDIA®SLITM (Scalable Link Interface) technology works:
In an SLI configuration, two/three SLI-ready graphics cards of the same model and the same manufac-
turers are connected together via SLI bridge connector in a system that provides two/three x16 PCI
Express slots to scale graphics performance. The picture below shows that two and three graphics
cards are linked in parallel in an SLI configuration.
