NVIDIA SLI is a revolutionary technology that allows two NVIDIA SLI graphics cards to work
together to deliver incredible 3D graphics performance.
To assist the do-it-yourself community, NVIDIA is providing the following guide on how to set-up
an NVIDIA SLI system.
Note: this guide assumes basic knowledge of how to build or upgrade a PC. If you do not feel comfortable with this level
of know how, please refer to our list of where to buy pre-built NVIDIA SLI systems

STEP TWO
Determine your power needs:
Based on testing at NVIDIA’s SLI Validation lab, the following power supply suggestions should
be followed.
NVIDIA SLI System Type Minimum Recommended PCI Express Power
Supply
High-End: GeForce 6800 Ultra 500W–550W, +12V @ 30A
Mid-Range: GeForce 6800 GT or 6800 420W–480W, +12V @ 25A
Entry-Level: GeForce 6600 GT 350W–420W, +12V @ 20A
If the power supply specifies two 12V windings (i.e. 12V1 and 12V2), then these current numbers
can be added together to check against the specifications described above.
For systems with the 6800 Ultra or 6800 GT, please make sure the power supply also contains a
PCI Express auxiliary power supply connector:
