GV-N28-1GH-B Graphics Accelerator
The GV-N28-1GH-B graphics card is a performance optimized high-end card. Power is taken from the
PCI Express host bus as well as the 8-pin and 6-pin PCI Express power connectors.
Without auxiliary power provided to the GV-N28-1GH-B graphics card, an LED on the bracket goes red
and the graphics card will not boot. In addition, the connector that is not adequately powered will turn
red.
The table below outlines the different possible scenarios as well as the resulting behaviors.

We suggest you using a power supply that provides a 8-pin PCI Express power cable instead
of using the included 8-pin power adapter. If you want to use the included 8-pin power adapter,
make sure at least 12V/15A current is supplied to each 4-pin power connector on this adapter.
Failure to do so may jeopardize the stability of the graphics card.
Incorrect Connection
(The two 4-pin power connectors on
the adapter are connected to the same
system power supply cable.)
Correct Connection
(The two 4-pin power connectors on the
adapter are connected to two independent
system power supply cables.)
