Our advice

MUPSU-1

The MUPSU-1 power supply was specially developed for MU-format modules (dotcom), which require additional 5V, as well as -15V and +15V.
The 5V rail has a maximum current of 1200mA, making it ideal for large sequencers or digital modules.
-15V has a maximum current of 670mA,
+15V has a maximum current of 670mA.
(I personally use the power supply with a MOTM to dotcom (MU) cable for my MOTM modules such as the MOTM650, MOTM730, Q960, and Moon Modular M569 and M568.)
The board contains coils and capacitors to ensure EMC compliance.

The package includes the assembled circuit board; additionally, you will need (not included) a wall-mounted power supply, e.g., 12V/2A, as well as a suitable socket and cable for connecting to the circuit board.
The MUPSU-1 power supply can be switched on/off using an optional switch, or a wire jumper can be installed in the screw terminal.
