ISTRIBUTION
The EA-750 PSU uses four separate +12-volt power rails. Different connectors are hooked up to separate circuits to
aid in the balanced distribution of power between devices in your computer. The engineers have allocated the rails
to different connectors to prevent voltage sags in one device due to sudden demands for power in another device.
