ISTRIBUTION
The CP-850 uses four se12V 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, as shown in Table 3, to prevent voltage
sags in one device due to sudden demands for power by another device.
