1. A power supply device with dual power source planes, comprising:
a plurality of controllers connected in parallel;
a first Power Supply Unit (PSU) power source group and a second Power Supply Unit (PSU) power source group, wherein the first Power Supply Unit (PSU) power source group and the second Power Supply Unit (PSU) power source group each comprises two Power Supply Unit (PSU) power sources connected in parallel, and the first Power Supply Unit (PSU) power source group and the second Power Supply Unit (PSU) power source group are respectively located on two independent power source planes; and
a power source backboard, wherein the power source backboard comprises a first copper skin layer and a second copper skin layer, which are not connected with each other, the first Power Supply Unit (PSU) power source group is connected to the input end of each controller by means of the first copper skin layer, and the second Power Supply Unit (PSU) power source group is connected to the input end of each controller by means of the second copper skin layer; and
each controller is configured to combine the electric current from the first Power Supply Unit (PSU) power source group with the electric current from the second Power Supply Unit (PSU) power source group, respectively, and output the combined electric current;
wherein the power supply device further comprises a management board, each controller is connected to the management board;
wherein the management board comprises a first management board and a second management board, and the plurality of controllers connected in parallel comprise a first controller, a second controller, a third controller and a fourth controller;
the combined electric current of the first controller is combined with the combined electric current of the second controller again to obtain a first target combined electric current, the first target combined electric current is respectively output to the first management board and the second management board by means of the power source backboard; and
the combined electric current of the third controller is combined with the combined electric current of the fourth controller again to obtain a second target combined electric current, the second target combined electric current is respectively output to the first management board and the second management board by means of the power source backboard.
