Power backplane assembly and power supply module

A common redundant power supply (CRPS) power backplane assembly, comprising:

• a backplane body for plugging in at least two power supplies and each power supply outputting a first voltage which is 12V;
• a conversion circuit board electrically connected to the backplane body, the conversion circuit board parallel to but not on the same plane as the backplane body, the conversion circuit board directly receiving the first voltage from the backplane body and converting the first voltage into a second voltage;
• and
• an output circuit board electrically connected to the conversion circuit board, the output circuit board parallel to but not on the same plane as the conversion circuit board, the output circuit board directly receiving the second voltage from the conversion circuit board, the output circuit board comprising a first output connector and a second output connector, wherein the first output connector is configured to output the first voltage, and the second output connector is configured to output the first voltage and the second voltage.
