We looked inside the PS4's power supply (AC/DC converter) module. We took out several screws to remove the cover of the module and examined the main power semiconductor devices in it. We estimated the types, specifications and manufacturers of the devices from the characters printed on the packages (Fig. 2).

#1: STMicroelectronics' MOSFET. The characters on its surface read "24N60M2." It has a drain current of 18A and maximum on-resistance of 0.19Ω. Its withstand voltage is about 600V.

#2: STMicroelectronics' diode. The characters on its surface read "STTH8R06FP." It has an average forward current of 8A and forward voltage of 1.4V (standard). Its withstand voltage is about 600V.

#3: Toshiba's MOSFET. The characters on its surface read "K12A60U." It has a drain current of 12A and on-resistance of 0.36Ω (standard). Its withstand voltage is about 600V.

#4: Fairchild Semiconductor's MOSFET. The characters on its surface read "035N06B." It has a drain current of 88A and on-resistance of 2.91mΩ (standard).

#5: STMicroelectronics' diode. The characters on its surface read "STPS20400CFP."

According to Sony Computer Entertainment (SCE) Inc, the efficiency of the power supply module reaches 90% or higher, depending on operating status. The efficiency of the PS3's power supply module reaches 80% or higher.
