5.1 Power Supplies
The base system includes a single 250W power supply. This unit provides power to the planar and the two internal hard drive bays. Power will be
Standard VRD (Voltage Regulator Down) modules that conform to VRD11.1 specification are used. This reduces the board layout complexity while offering design modularity. As processor speeds increase, a newer VRD can be used to accommodate the power increase with no need to
5.2 Power Supply Connectors on the Planar
There are 2 separate power supply connectors on the planar. One connector is an ATX connector (2x12) and the other one is a 2x2 connector to provide an additional two pins for +12V. The connector Pin definition (2 x 12 power connector) is not ATX standard.
The 2x12 connector provides 3.3V, 5V, 12V, and 12V standby to the system. (3.3V standby to system is generated from 12V standby).
