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 SLI System Type High-End: EVGA GeForce 8800 GTX Mid-Range: EVGA GeForce 7950 GT Entry-Level: EVGA GeForce 7600 GT Minimum Recommended PCI Express Power Supply 750W and up, +12V @ 40A 500W-550W, +12V @ 30A 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. The NVIDIA SLI power supply recommendations are based on the following test configurations: ‰ High-End NVIDIA SLI Configuration: ¾ Dual EVGA GeForce 8800 GTX Graphics cards ¾ Intel Core 2 Quad EE 775-pin CPU ¾ Two or more HDD, including RAID 0,1, 0+1 or 5 configurations ¾ Two optical drives ¾ PCI sound card ‰ Mid-Range NVIDIA SLI Configuration: ¾ Dual EVGA 7950 GT Graphics cards ¾ Intel Core 2 Duo ¾ Single HDD ¾ Two optical drives ¾ PCI sound card ‰ Entry-Level NVIDIA SLI configuration: 105
