The PS5 teardown also gives you a good look at the CPU itself, its 16GB of GDDR6 memory, and the custom SSD controller. The 350W power supply is built-in, so you won’t have an ugly brick hanging off the back of your machine.
There are still some questions left about the PS5, including its still-mysterious interface. We wouldn’t be surprised if a third-party teardown went further. However, this might just answer many of your questions about the design. Like Microsoft, Sony was interested in a design that runs quietly, not just quickly.
