Power Supply

• Some graphics cards that are capable of supporting SLI technology may require an
external power cable.
• As SLI technology based computers support up to two high-end graphics cards,
the load on the computer's power supply can increase significantly. A minimum
of a 450W Power Supply Unit (PSU) is recommended.
Note: An inadequate power supply can result in erratic and unpredictable system
Note: For the latest updates on SLI technology-certified power supplies, see
