Why Replace the OEM PSU?
The original Saturn PSU is an aging AC-to-DC converter, prone to:
- Inefficiency and heat
- Noisy output affecting video quality
- Risk of damage from incorrect voltage input (e.g., plugging 240V into a Japanese 110V system)
Voltage Settings – Set with SW1 Switch
Refer to the label on the back of the board or follow this guide:
| Saturn Type | Region | Compatible? | Voltage Setting |
|---|---|---|---|
| Type A (VA0) | All | ❌ Not supported | N/A |
| Type B (VA1–VA5) | All | ✅ Supported | +9V |
| Type C (VA6+) | NTSC | ✅ Supported | +9V or +12V |
| Type C (VA6+) | PAL | ✅ Supported | Use original voltage, or default to +9V if unsure |

Install Guide
See here for tutorial and review.
I recommend a Phillips #2 screwdriver is used for the install.
- Unscrew the two power supply and five bottom shell screws as shown in the photo.
- Remove the top lid and then remove the single power board screw (see photos).
- Fit the robot_retro board in exactly the same way as the OEM power board was removed. Reattach the single original screw.
- 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.
- Button up the console.

I installed it in a Japanese Sega Saturn VA1. The installation was easy, it fits perfectly, and the PCB is beautifully made (it even made me want a clear shell!). From now on, I’m free from the hassle of replacing capacitors, and when viewing on a CRT, I really do feel the image quality has improved—there’s noticeably less noise and no screen wobble.
Thank you so much for this amazing product. Even ordering from Japan, it arrived in just one week!
If I may make one request:
Please consider creating a USB-C power board for the PC Engine Duo.
・The power jack is on a separate board from the main board, so I believe it would be easier to commercialize.
・The original AC adapter is practically a weapon.
・There are very few ideal replacement adapters. On top of being center-positive, the connector size is non-standard.
・When buying a replacement AC adapter, you have to convert it to center-positive and then further adapt the connector size.
For these reasons, I believe PC Engine Duo users around the world would truly appreciate it.
Thank you again from Japan!
Works really well and easy install. The cover for the usb-c port though I think needs to be ever so slightly trimmed down. When I screw down the screws all the way, the usb-c port is sunkin in, not flush and the cable won't make completed connection in the port. I fixed this by not tightening the two screws all the way and it works fine. Much better option imo than the ReSaturn PSU which is what I bought before this. Get this, 100% worth it.
Updated a US version 6 Saturn with this power supply. It was super easy to change out and works flawlessly. I paired this with an Anker 45 watt block and usb-c cord. Excellent quality look and performs as advertised.
Great quality and very easy to fit.
Excellent mod to have. It's very easy to install and it just work out of the box.
Now I can play with my japanese Saturn !
