ColecoVision Power Supply Replacement 12V/5V/-5V Regulated PSU Safe & Reliable

ColecoVision Replacement Power Supply

Bring your ColecoVision back to life with this reliable and affordable replacement power supply, designed specifically for the console’s needs.

Many aftermarket options provide the required 12V / 5V / -5V rails, but they’re often overpowered and overpriced. For example, ATX power supplies can output 450W or more, while the ColecoVision only needs about 36W. This design delivers the correct voltages efficiently — without unnecessary bulk or cost.

⚙️ Technical Details

• Operates from a single 12V 2A power supply, connected via a standard 2.1mm x 5.5mm barrel plug.

• The 12V line is regulated down to 5V using two DC-to-DC buck converters.

• The -5V line is generated through a charge pump inverter from the regulated 5V.

• The charge pump provides up to 0.1A, which is more than enough for the 4116 VRAM that uses the -5V rail.

The power supply connects directly to the back of the ColecoVision, just like the original.
The connector housing is 3D printed and uses Molex connectors for a clean, secure fit.

📦 What’s Included

• High-quality 12V 2A UL-listed switching power supply

• Custom-built converter box providing 12V, 5V, and -5V outputs

• Ready to plug in and power up your ColecoVision

⚠️ Important Note

Original ColecoVision power supplies often drift over voltage with age, which can damage your console. This replacement ensures stable and safe operation.
