SUFFICIENT AIRFLOW
The Wildcat Realizm 800 has its own cooling system for circulating air across the graphics card from within
the system case; however, the cooling system must have sufficient clearance to operate properly. A poor
cooling environment could lead to extreme thermal conditions and system failure. To help avoid this, check
the following:
There is enough room around the graphics card for the cooling system to pull cool air in and
exhaust hot air out of the graphics card.
No cables or wires are around the fan that could block airflow to the card or catch in the fan,
preventing the fan blades from turning properly.
SYSTEM INTEGRATOR INFORMATION
To ensure optimum graphics card fit and performance, it is recommended that system and add-in card
designers refer to the PCI Express x16 Graphics 150W-ATX Card Thermal and Mechanical Guideline
for Desktop Systems documentation available from
www.pcisig.com
Installing the Wildcat Realizm 800
Refer to your computer’s documentation for instructions on opening and closing the computer, identifying the
PCI Express slots and adding expansion cards.
1. The Wildcat Realizm 800 requires two slots:
One for PCI Express
An adjacent slot for clearance of the cooling shroud
Remove the slot covers for the PCI Express slot and the adjacent slot that you intend to use.
2. Push the card firmly and evenly into the correct x16 PCI Express slot until it is fully seated.
NOTE: The cooling fan on the graphics card must have sufficient
clearance to ensure proper airflow. Blocked airflow can cause the
graphics card to overheat. Ensure there are no cables or wires
around the fan that could block airflow to the card or catch in the
fan, preventing the fan blades from turning properly.
3. Secure the bracket of the graphics card to the computer chassis.
Connecting Auxiliary Power to the Wildcat Realizm 800
Before you restore power to the system, you must connect auxiliary power from the system power supply to the
graphics card. There are two scenarios for connecting auxiliary power to the Wildcat Realizm 800:
Scenario 1:
Your power supply has a High-End power connector designed to plug into a x16 PCI Express
graphics card. If this is the case, simply plug this power connector into the Wildcat Realizm 800 (see
diagram below). Go to “Completing Installation” immediately following this section to finish installing
the graphics card.
NOTE: The PCI Express high power connector is a black, 6-pin
connector originating from the system power supply. Use extreme
caution when identifying this connector. Some power supply
connectors can look similar to the PCI Express high power
connector, but are keyed slightly different. Do not force the PCI
Express high power connector into the graphics card. If force
seems necessary, you may not have the correct connector. Make
sure the connector from the system power supply is correctly
keyed for the graphics card.
