Just put toghether a new system with an evga e-geforce 8800gt superclocked, whenever I boot the system I get the nvidia sentinel message "not receiving sufficient power." So I made sure all the power cables were plugged in, and the pcie cable was securely fastened to the card, still same error. So I tried using the 2 molex to pcie adapter that came with card, still same error. So I unplugged the power to everything except the mobo, cpu, boot drive and 8800gt, still same error. Checked voltages on PSU, and they are fine. So I'm not sure what could be causing this error.
