Is your PS4 disassembled because you cleaned it, and you are not sure how to put it back together? Did you replace the thermal paste because the PS4 Pro fan was noisy? Did you replace the battery? Good. After learning how to disassemble the PS4 Pro and performing the internal maintenance, let's see how to reassemble the PlayStation 4 Pro correctly before causing any damage.
First, I hope you followed my advice and kept the screws near the corresponding covers and shields. This keeps them organized and helps ensure that none are forgotten during reassembly.
Start by reinstalling the central metal plate that contains the heatsink, making sure it is oriented correctly. Take care not to pinch the CD/DVD/Blu-ray drive cables or any of the other cables running around the plate.
The CD/DVD/Blu-ray drive is already back in place: we removed it only as an experiment, not because it actually needed to be removed.
Reassembling the PS4 Pro Motherboard
Now take the PS4 Pro motherboard, where the thermal paste has already been applied to the CPU. Check that the thermal pads are present and correctly positioned over the individual power-regulation chips.
If everything is in place, turn the motherboard over and lower it onto the metal plate, aligning the CPU with the heatsink.
Do not follow the method shown in the next image. If you did not remove the power supply, reassembly becomes difficult because the power contacts and connector must be reconnected with very little room for your fingers. This is why, in the article on how to disassemble the PS4 Pro, I recommended removing the power supply from the other side as well.
Let's continue reassembling the PlayStation 4 Pro. Place the motherboard onto the plate with the CPU aligned with the heatsink. Insert the rear edge first, on the side with the USB ports.
Make sure that no cables or connectors are trapped or pinched under the motherboard.
Reinstall the lower CPU support. First position the spacer, then install the X-clamp. Finally, tighten the four Phillips screws gradually in a diagonal cross pattern until all four are secure, firmly but carefully.
Before reinstalling the metal shield over the GDDR5 RAM, make sure all the thermal pads are present and aligned with their corresponding RAM chips.
Now reinstall the small black Phillips screws.
How to Reassemble the PlayStation 4 Pro: The Power Supply
Turn the console over to reinstall the power supply. The connector and power contacts are clearly visible. Make sure the power contacts are straight.
Before reinstalling the power supply, if you want to be particularly thorough, you can apply a small amount of electrical contact cleaner to the connector that receives the motherboard power contacts.
Reconnect the small 4-pin cable from the PS4 Pro power supply.
Install the power supply in the correct orientation and lower it vertically into place. This allows the power contacts to engage without bending.
Reinstall the five T9 Torx screws, remembering that they have different lengths, as shown in the first article.
Reinstalling the PS4 Pro Metal Shield and Connectors
Turn the console over again and place the metal shield over the PlayStation 4 motherboard. Make sure no cables or connectors are trapped underneath.
We can now reconnect the cables. The smaller ribbon cables slide directly into their connectors. Before inserting the wider ribbon cable from the CD/DVD/Blu-ray drive, make sure the connector's locking tab is open in the vertical position. Close the tab after the ribbon cable is fully inserted.
Secure the Wi-Fi and Bluetooth coaxial cables in their respective clips.
Press the small U.FL connectors for the Wi-Fi and Bluetooth cables straight down onto their sockets. Check again that the cables are routed through the correct retaining clips.
There are still a couple of connectors to reconnect, including the cooling-fan connector.
Perfect! The PS4 Pro is almost ready...
Reinstalling the PS4 Pro Plastic Covers
To reinstall the PS4 top cover, engage it from the rear of the console first.
Once it is in position, press it down to engage the retaining clips.
The bottom cover is similar. Engage it at the front of the console first, then press it into place to lock the clips. Be careful not to break the small screw tabs where the warranty stickers were located.
Installing the PlayStation 4 Hard Drive
We are now at the final steps. You know how to reassemble the PlayStation 4 Pro! Slide the hard drive into its bay with the connector facing the inside of the console.
Reinstall the Phillips screw that secures the hard-drive tray.
Now reinstall the three T9 Torx screws. Once they are tightened, the two warranty labels can be put back in place.
The only remaining step is to snap the PS4 hard-drive bay cover back into place.
An Excellent Result!
The result is impressive: the Sony PS4 Pro looks *almost* new! The fan no longer sounds like an airplane; it speeds up only when necessary and then returns to a lower speed.
And here is a family photo, with the PS4 alongside its ancestors!
