A printer circuit board (PCB) includes a voltage regulator module (VRM) and a body. The VRM supplies power to a first load and a second load. A decoupling circuit is set on one side of the first load, and the decoupling circuit is electronically connected to the first load. The body includes a multi-layer circuit board. The VRM, the first load, and the second load are positioned on one layer of the circuit board, where the VRM is electronically connected to the first load, but the VRM and the first load are electronically disconnected with the second load. The VRM, the first load, and the second load two are positioned on two other layers of the circuit board, where the first load is electronically connected to the second load, but the first load and the second load are electronically disconnected to the VRM.
