Title

Basics

The OEM Saturn power supply is a combined 110v/240v AC to DC converter. This is inefficient and noisy, which can manifest in a “fuzzy” video signal. 

Also, plugging in a UK 240v supply to a 110v Japanese Saturn can cause damage.

Compatibility

This upgrade is compatible with all Saturn models with the exception of VA0 (Type A power supplies). 

See here for information on how to determine your Saturns model number.

What the robot_retro Saturn Power Board Offers

  • Powered from a 15v or 20v Power Delivery USBC charger (e.g. Ankur, Dell, uGreen, etc.). Most 30W charger USBC will work (they have to be able to output 15v/20v). I recommend the uGreen Nexode mini 30W as this both excellent quality and value.
  • Works with all PAL and US/Japan NTSC models except VA0 (Type A power supplies). Also removes the risk of accidentally plugging in 240V into a 110V system and causing damage.
  • Works perfectly with Fenrir.
  • Includes 5V header for Noctua fans and dedicated 12V/9V/5V/3.3V/GND 2.54mm pin headers for other power-hungry mods
  • Tested to be between 90 and 95% efficient across all loads. 
  • Low signal noise and heat.
  • Drop in solution. No soldering, wires or complicated install required.
  • No flashing LEDS, perfect for clear shells.
  • Overvoltage, over temperature and fused supply.
  • Multicoloured 3D printed spacer.

Other 3D spacer colours can be printed from the files here.

Voltage Setting

The following voltage should be set using SW1 (instructions are also on the back of the PCB):

  • Type A (VA0) = Not compatible so N/A
  • Type B (VA1 to VA5) = +9V
  • Type C NTSC (VA6+) = +9v or +12v (either will work)
  • Type C PAL (VA6+) = Check original or use 9v if unsure

Installation

See here for tutorial and review.

I recommend a Phillips #2 screwdriver is used for the install.

  1. Unscrew the two power supply and five bottom shell screws as shown in the photo.
  2. Remove the top lid and then remove the single power board screw (see photos).
  3. Fit the robot_retro board in exactly the same way as the OEM power board was removed. Reattach the single original screw.
  4. Fit 3D printer USBC spacer and attach the two power supply screws. Note, this does require a gentle push to get the screws to tap into the 3D spacer. I recommend to fit the first screw around halfway, then start the second while pushing down on the 3D spacer (towards the PCB). Once both are tapped, drive them both home. Do not overtighten.
  5. Button up the console.
