After a few years in the market our Saturn consoles are growing older, and problems related to bad caps in the stock power supply, or problems with the infamous voltage regulator (prone to fail from the very beginning) are commonplace. This can affect the voltage of the CD lens and, of course, the voltage the ICs on the motherboard need. Recapping or swapping the whole psu can obviously be a solution, but the variety of models existing makes it sometimes hard to find a match. To solve all this REXUS NEXUS designed the ReSaturn PSU, a 12v power supply that works with all Saturn revisions (from *VA1 to VA15) either NTSC-J, NTSC-US, or PAL.
12v AC/DC adapter with 5.5×2.1mm barrel size positive center tip is required and available as an option
Compatible with all ODEs (Optical disc emulators)
No soldering required
Please Note: The optional high quality MeanWell power adapter is highly recommended by the manufacturer, who warns against using cheap power adapters with these units. If you want to save money and use the same MeanWell adapter on all your rePSU units (ReDream, ReSaturn, RePSX, and ReN64), they are all compatible with the same power adapter.
The Saturn had 3 different sorts of PSU:
Type A (GND,GND, 3.3v, 5v, 9v)
Type B (GND,GND, 3.3v, 5v, 9v)
Type C (GND, GND, 5v, 5v, 9v/12v) or (GND, GND, 5v, 5v).
All these combinations are possible with the ReSaturn PSU, see the installation guide.
The ReSaturn includes a block connector with +5V that will allow MODE users to plug in the cable for extra juice straight to the PSU. This has sorted out issues related to crackling sound with the MODE.
Please note that this design follows PCB layout best practice and that the choice of components is tailored to the specific needs of the Saturn. All components are high quality. When used with a good 12v adapter, this PSU offers a ripple+noise output of around 30mV on the 3.3v and 5v rails under load.
