Psu power rails information

I`m interested in looking into making a portable ps4. But i need more info on the actual psu.

I`m thinking to keep the case as it is just bypass the power supply and feed it the right voltage, akin to a laptop (to which it`ll most like be attached to)

Any idea if the output is a dual rail system? The tear down pointed toward a 12v rail and a 4.7v rail but something about a single 12v but with higher amperage.

Thank you in advance and thank you for tearing these consoles apart for us that don't want to try it first without knowing what's there.
