Drop-in Saturn PSU replacement

The Yoetaun Rev V2.1 Saturn PSU is a new drop-in replacement power supply for Sega Saturn consoles. It draws power from an external 12 V source and keeps the original console power button. Installation requires no modification to the hardware. The board measures approximately 4.8 cm by 4.8 cm and comes in black.

Retro console owners and modders

This unit suits owners of any Saturn model who want less internal heat and more free space for additional modifications. It is not for users who must retain the original internal power supply untouched. It is also not for anyone without access to a suitable 12 V external supply.

12 V external input requirement

The single specification that decides fitment is the 12 V external input; the console must be powered from that source rather than from mains voltage directly. The package includes British, European, Australian and American plug adapters plus a multi-plug adapter, cable and manual.

Questions about this item

Will the external 12V adapter or the internal SaturnPSU board need replacing first?

The external 12V power supply is a standard wall-wart that can be swapped independently; the internal SaturnPSU board has no moving parts and is expected to outlast the original supply it replaces.

What thermal limit appears first during long gaming sessions?

The replacement board removes the original supply's heat source, so the console's own components set the temperature ceiling rather than the SaturnPSU itself.

How much noise and heat does the SaturnPSU add when the console runs all day?

The board is completely passive and produces no fan noise; by moving the 12V conversion outside the case it lowers internal heat and frees space for other mods.
