While NVIDIA recommends an SLI-Ready power supply, the following table
provides some general power supply recommendations based on testing
performed in the NVIDIA SLI validation lab.

Table 6.

Recommended Power Supplies

SLI System Type

Minimum Recommended PCI Express
Power Supply

High-End: EVGA GeForce 8800 GTX

750W and up, +12V @ 40A

500W–550W, +12V @ 30A

Entry-Level: EVGA GeForce 7600 GT

350W–420W, +12V @ 20A


If the power supply specifies two 12V windings (i.e. 12V1 and 12V2), add these
numbers together to check against the specifications described above.
For systems with the 8800 GTX or 8800 GT, please make sure the power
supply also contains PCI Express auxiliary power supply connectors. If your
power supply does not have a PCI Express auxiliary connector (6-pin
connector), please contact your graphics board partner for an HDD-to-PCI
Express power adaptor.
