It's faster, it's smarter, and it costs $700, and doesn't come with a disc drive.

And if you want Sony's latest and greatest controller, that'll cost you an additional $200.

Regardless of the price, it's the most advanced gaming system humans have made to date.

But you probably haven't seen what's inside that puts it at the top of the console wars.

This is every piece of the PlayStation 5 Pro and the DualSense Edge controller.

Each can be removed by pulling on these four white plastic tabs without any tools.

The standard and slim models of the PlayStation also have removable side panels, but they're not interchangeable with the Pro model.

If you opt to pay extra for the disc drive, this is where you would slide that in.

Next, we're gonna take off the CMOS battery bracket.

A notable improvement in the PS5 Pro's design is the addition of a dedicated slot for easy access to the CMOS battery.

Located just below the removable faceplate, this compartment allows users to replace the CMOS battery without disassembling the entire console.

This small but essential component ensures the system settings and clock data remains intact, even when the console is unplugged for extended periods.

It probably doesn't need to be replaced for five to 10 years though.

Here you can see both the Wi-Fi and Bluetooth antenna.

The PS5 Pro supports Wi-Fi 7, though you need a Wi-Fi 7 router to make use of those new features.

Here is the board that houses the USB-C ports for connecting various accessories like external storage, controllers, and even the PlayStation Virtual Reality 2.

Now that we've taken off the screws, we can flip it and see the ports.

These are soldered on, but what's nice about having a dedicated board is that you can replace it independently without fussing with the motherboard.

Next, we're gonna take off this expansion cover for the M.2 SSD extension.

In addition to its internal storage, the PS5 Pro features an expansion slot where users can add M.2 solid state drives, and there are mounting holes for every M.2 drive length.

The fan is what drives the heat out of the device.

It's easily accessible, which is great for cleaning and replacement.

First, we'll take off this cover that protects the fan's power connectors.

These are JSD connectors, or Japan Solderless Terminals.

You can see the positive, negative, and ground wires.

Next, we'll take off the four screws securing the fan.

And this is a good time to note that Sony did a cool thing where they added in these little indicators next to each screw.

So there's three dots, two dots, and no dot.

Each corresponds to the length of the screw.

So when you're disassembling and reassembling, you'll know which screw is needed.

We're using this screw map here to keep track of which screws we're taking out.

So this fan is bigger than those in the PS5 and PS5 Slim.

What this means is that it's more powerful and it can drive more air, but it needs less power to produce the same air output as previous fans.

It's important to note here that this console generates a lot of heat.

And what gets rid of the heat are the fan and the heatsinks.

These heatsinks pull the heat out of the chips and then drive it along down to the fan.

Here you can see the fins of both heatsinks.

That's where the heat will be drawn to and wicked away by the fan.

To get to these heatsinks and the rest of the components, we'll take off this inner plastic shell.

Part of this includes removing this tamper-proof warranty sticker, which actually doesn't mean anything in the United States.

Thanks to the Magnuson-Moss Warranty Act of 1975, consumers in the U.S. can open their consoles for maintenance without fear of losing warranty coverage.

And 10 screws later, we have access to the heatsinks and inner components.

We'll remove the wires that run to the Wi-Fi and Bluetooth antenna connected via coaxial connectors.

And we'll also remove the CMOS battery board and then pry out that heatsink.

This is the first smaller heatsink, and it's actually only held in place by thermal putty, which draws the heat into the copper piping.

Here you can see the copper pipes, which draws the heat from the electronics to the fins.

Next, we're going to remove this metal shield protecting the motherboard by removing each of the 39 screws.

We'll also have to remove this cover protecting the main board's interconnection to the I-O board.

But even though the 39 screws have been removed, it's still adhered by thermal pads, so we've got to use a decent amount of force to pry it off.

So the PS5 Pro generates tons of heat, and it needs both of these sinks to keep it from overheating.

This cooling system makes up for the majority of the 6.8 pounds or 3.1 kilogram total weight of this console.

And if you look here, you can see two important prongs.

These connect the board to the power supply.

And here is that 390-watt power supply, which powers your console from a wall outlet.

Removing the sinks and shield reveals the motherboard in all its glory.

First, we'll take off these brackets to reveal the APU, or Accelerated Processing Unit.

This one is an AMD SoC, or System on a Chip, made in Taiwan.

It's an integrated system that contains both your GPU and CPU, and it's the heart of the PS5 Pro.

Here you can see the liquid metal on the back of the APU.

Liquid metal performs essentially the same function as thermal paste, taking heat away from the board.

Liquid metal is great for this, because it has such a high conductivity.

The downside is that it can, if it touches the board, connect certain components and short-circuit your device.

New to the PS5 Pro are these etchings, which keep the metal evenly distributed, preventing it from pooling.

And this foam padding keeps the pool of metal in place.

So this APU is why we can use AI to upscale graphics.

The process Sony uses for this is PSSR, which stands for PlayStation Spectral Super Resolution.

What that means is artificial intelligence is used to fill in gaps where the AI thinks pixels should be to create higher resolutions, even if there aren't normal native high resolutions in that area.

And here we have the IO controller, likely from Samsung sourced in South Korea.

What this does is control signals going in and out of the device.

And these two chips here, these are both the NAND flash storage, made by Kioxia in Japan.

NAND is a type of data storage architecture, and it's important because it can retain its information even without power.

Each of these chips is one fourth of the storage.

There's going to be two more of the same chips on the back that hold the remainder of the storage.

The PS5 Pro comes with a total of two terabytes.

So each one of these holds 500 gigabytes.

And then down here, these two components handle USB-C power and data management.

This one is made by Texas Instruments, obviously an American company.

It is a USB type C, 10 gigabit bi-directional linear redriver.

And what that means is in this context, it helps regulate the flow of data.

Same thing goes for this one, also regulating whatever the data is coming in and out of the USB-C.

This one is a Wichtech, a Taiwanese company.

And then we have these two chips, which are multi-phase controllers, made by Infineon, a German company.

What these do is split the electrical current off into different ranges.
