Buying Guide: Choosing the Right Arcade Power Supply

After testing 15 power supplies across dozens of cabinet builds, I’ve learned that selecting the right unit requires understanding your specific needs. The best arcade power supplies for cabinet balances voltage requirements, current capacity, safety certifications, and reliability.

Voltage Requirements Explained

Most JAMMA arcade boards require three voltages: +5V DC for logic and board operation, +12V DC for audio amplification and some graphics, and -5V DC for audio in older boards. Modern boards often skip the -5V requirement, but vintage hardware from the 80s and 90s typically needs all three. Always check your board’s manual before selecting a supply.

The +5V rail is typically the most demanding, drawing 5-15 amps depending on the board and any attached accessories. This is why single-rail supplies like the Arcity 5V/16A options are popular for dedicated cabinets. Multi-voltage supplies offer flexibility but may have shared capacity across rails.

Switching vs Linear Power Supplies

Modern arcade cabinets almost exclusively use switching power supplies due to their efficiency, compact size, and lighter weight. Linear supplies, while offering cleaner output, are large, heavy, and inefficient. The switching supplies in this roundup provide 80-87% efficiency compared to 50-60% for linear designs.

The forum community consistently recommends switching supplies for new builds. As one Redditor noted about HDMI upscalers for retro gaming and similar modern hardware, the efficiency and thermal advantages make switching supplies the clear choice for enclosed cabinet installations.

Power Calculation for Your Setup

Calculate your total power needs by adding the current draw of each component at its required voltage. A typical JAMMA setup might need 8A at +5V, 1A at +12V, and 0.5A at -5V. Add 20% headroom for reliability and future expansion. This example would need at least a 10A +5V supply, making something like the Arcity 5V/16A models appropriate.

For LED-heavy modern builds, calculate LED strip power separately. 60 LEDs per meter at 60mA each equals 3.6A per meter for 5V strips. A 5-meter run would need 18A, pushing beyond standard supplies and toward the high-current Mean Well LRS-350-5.

Installation and Wiring Basics

Always wire your supply with the cabinet power unplugged. Connect AC input first, then verify proper voltage at the DC outputs before connecting any boards. Use appropriate wire gauge, typically 18-22 AWG for arcade applications. The +5V connection should use heavier wire due to higher current draw.

Mount the supply where it gets adequate airflow. Even fanless units benefit from convection cooling. Never cover the supply with insulation or obstruct ventilation holes. Some builders add a small exhaust fan near the supply for extra cooling in tight spaces.

Safety Considerations

Always look for safety certifications like UL, CE, and CSA. These indicate the supply has been tested for safety and meets international standards. The forum community consistently prioritizes certified supplies, especially for cabinets accessible to children or in public spaces.

Include a fused power switch between the wall outlet and your supply. This protects both the supply and your cabinet from fault conditions. Never bypass the fuse in the supply itself, and always replace with the exact same rating. The Mean Well supplies in this roundup include comprehensive protection circuits that add important safety layers.
