EVGA 122-CK-NF68-XX manual Recommended Power Supplies

Installing and Configuring the EVGA nForce 680i SLI Motherboard

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

	Minimum Recommended PCI Express
SLI System Type	Power Supply
High-End: EVGA GeForce 8800 GTX	750W and up, +12V @ 40A
Mid-Range: EVGA GeForce 7950 GT	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.
