MSI N480GTX Lightning Preview – The Best Just Got Better

We also found four, small switches on the back. One is located near the PCI-e x16 connector while the other three are situated along the edge of the graphics card. Each has a different function, from shutting down the OCP, adjusting PWM clock, to enabling extreme overclock.

Four prodilizer chips are installed near the switches.

On the rear end of the graphics card, you can see a line of small, LED lamps, which will lit up according to the graphics card’s current load condition.
