PS2 USB PD Plate

Information

This mod enables you to delete the old PS2 FAT PSU and replace a segment of it with USB PD.

Parts

The following parts are required to complete this mod:

• USB-C PD Trigger Board (Terminal Version): https://www.aliexpress.com/item/1005006005033136.html?spm=a2g0o.order_list.order_list_main.5.7d041802m3hibV

Important Notes

• This has only been tested in a SCPH-39001 PAL case, I do not intend to support anything else.
• While USB-C PD can do 12 volts, it is optional for the PSU. Therefore I have opted to use 20V as it is a requirement of the spec. 
• The USB PD PSU must provide 5 amps to meet the power requirements of the PS2.
• You CANNOT connect this directly to the motherboard's power in port, additional hardware is required to step down the 20V to 12V. I will not be providing any instructions on how to do this.
• The two holes to screw down the USB PD trigger board to the 3D model are just there for guides.

Build Instructions

1. Print the 3D model, I do not have any recommendations on print settings other than requiring supports for the front side if facing downwards.
2. On the USB-C PD Trigger board, underneath you need to solder the following two jumpers to bridge them:
   1. “20v” (The required voltage output we want)
   2. “PD Only” This disables Qualcomm fast charging as it is not what we want.
3. Align the USB-C PD trigger board inside the 3D-printed plate.
4. Using two small self-tapping screws gently screw them in. Note: You may need to place small washers underneath the PCB if the board is sitting too low.
5. Connect your positive and negative wires to the USB-C PD trigger board screw terminals.
6. Remove the old PS2 PSU, you do not need this if you are performing this modification. Note: You should already have figured out how you are going to convert 20v to 12v by this point
7. Mount inside fan bracket.
8. Enjoy

Files Provided

I have included the Fusion 360 project file alongside this project, please note that I am a novice Fusion 360 user and it's likely that tweaking values may break the model. So sorry in advance.

Step Down Converter

To step down the 20v to 12v, I used a buck converter (https://www.aliexpress.com/item/1005006408230252.html?spm=a2g0o.order_list.order_list_main.4.7d041802m3hibV). Finding a location for this was rather rough as I was also adding other mods that took up some extra spacer. Please note that careful consideration needs to be taken to mount this in such a way that it won't short on other internals.
