Hello,
I have a ASUS P8Z77-V Premium motherboard and 2x GTX660TIs running off a 750W power supply. When I connect one graphics card, everything works fine. When I connect the second one, the computer behaves slowly and crashes/freezes with no discernible cause -- regardless of whether SLI is enabled or SLI settings or whether the SLI connector is connected. I have confirmed both are receiving power by plugging a separate monitor into each one. I have tried swapping the graphics cards and they both appear to be working.
Does anyone have any thoughts or information that can help? Is this a valid configuration? Furthermore, should I try contacting Nvidia, EVGA, or ASUS directly?
Thanks
Jordan
