The PSU file format is an archive format used by PS2 save data management tools like uLaunchELF and mymcplus.
Usage
Obtaining a PSU file
From an actual PS2
By running uLaunchELF on an actual PS2, one can export PSU files from the PS2 Memory Card to USB or network.
From a PS2 emulator
PCSX2 stores the PS2 savedata in a virtual memory card file whose extension is .mcd. Each per-game savedata contained in the MCD file can be extracted to a PSU file by using mymcplus tool for example.
Extracting a PSU file
The best way to extract a PSU file would be to use pypsu by McCaulay if it was not bugged (for example on Jak X: "[-] month must be in 1..12", and on games that have a filename identical as the folder name, cannot export that file).
So the current workaround is to convert PSU to another savedata format.
For example, you can use
