Overview
Wiiu psu is an open-source printed circuit board by Lazr1026, from the Lazr1026/PSUPlusPlus repository on GitHub. It is a 2-layer board of 18 × 49.5 mm with 54 parts on 29 nets, routed with 122 tracks and 118 vias.
Its parts include 20 capacitors, 10 resistors, 5 ICs and 5 inductors. It belongs with the power boards of this library.
README
README.mdwiiu-psu
The wiiu-psu (or PSU++) is a regulator board for the Wii U, minus the core rails (1v/1.15v). It is based off the PSU-Plus, so all rails have a limit of 3A (this only really matters for 5v).
Features
- All low-current regulators required for the Wii U to function.
- Bonus 3v3 rail (STBY) for the RTC to power on the system.
- 1.25v regulator for WUP-01 motherboards (or if you wanted to remove the stock one).
- 1.25v can be enabled/disabled with a simple jumper.

The intent is to be used for the Wii U Mini, but if you find another use for this board, have at it!
There are two VIN pads. The smaller one is used to power the STBY regulator, while the bigger one is to power all of the other regulators.

Questions
How big is the Wiiu psu PCB?
It measures 18 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wiiu psu use?
54 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Wiiu psu KiCad files?
From the Lazr1026/PSUPlusPlus repository on GitHub, at the commit this page was made from: the board is wiiu-psu.kicad_pcb and its schematic wiiu-psu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wiiu psu design in my own project?
Its repository states no licence, so its author keeps all rights: ask Lazr1026 before reusing the design.
