The teardown of the PS3 has just begun. We moved on to break down the power supply module taken out of the chassis.

The power supply module has an elongated shape in accordance with the change in the internal structure. The shape of the power supply module in the former PS3 models is almost a square when viewed from above.

We started to disassemble the module but found it difficult to open its chassis. Though there were no parts bonded with adhesive, the upper and lower chassis were tightly attached to each other.

So, we inserted the tip of a flat-blade screwdriver into a small gap between the chassis and pried open the module. Then, we found a power supply board printed with the mark of Delta Electronics Inc of Taiwan.

"Whoa, this is interesting," said a power supply engineer who was looking at the power supply board. "I mean, the shape of this radiation fin."

The upper part of the module is slanted, and the upper part of the fin is slanted in the same manner. This shape corresponds to the outer design of the new PS3.

According to its specifications, the power consumption of the new PS3 is about 250W.

"It is not impossible to deal with 250W with a power supply module of this size if we try," the power supply engineer said.

We began to tear down the Blu-ray Disc device and the main board.
