How to Choose the Right Arcade Power Supply

Selecting the correct power supply for your arcade cabinet requires understanding voltage requirements, calculating amperage needs, and matching the supply to your specific build type. Here is what you need to know.

Voltage Requirements Explained

Most arcade cabinets require multiple DC voltages:

+5V DC: This is the primary voltage for game board logic circuits. The +5V rail must be stable and precise. Even small drops below 5.0V can cause random resets, graphical glitches, or complete failure. Always measure voltage at the board edge, not at the power supply terminals, to account for wire resistance.

+12V DC: Used for audio amplifiers, cooling fans, and some monitor chassis. The 12V rail is less sensitive to minor variations but should still remain within 5% of nominal.

-5V DC: Required by older sound chips in many classic arcade boards. If you are restoring a vintage cabinet, verify whether your board needs -5V. Many modern power supplies omit this rail, so check specifications carefully.

+24V DC: Used by some monitor chassis and coin mechanisms. Not all arcade power supplies include this output, so verify compatibility if your project needs it.

Calculating Amperage and Wattage

Determining how much power you need is crucial. Add up the current requirements of all components:

Typical JAMMA boards draw 2-5A at +5V. Add 1-2A for coin doors, 0.5-1A for LED lighting, and 1-2A for audio amplifiers. Always choose a power supply rated for at least 20% more than your calculated maximum load. This headroom ensures stable voltage and extends component life.

For wattage, multiply voltage by current for each rail and sum the totals. A 15A +5V rail (75W), 4A +12V rail (48W), and 1A -5V rail (5W) gives 128W total. A 150W or higher power supply provides adequate margin.

JAMMA Standard Compatibility

If you are building or restoring a JAMMA cabinet, ensure your power supply provides +5V, +12V, and ideally -5V outputs. The standard JAMMA pinout expects these voltages at specific positions on the edge connector. Most arcade-specific switching power supplies are JAMMA-compatible by design.

Switching vs Linear Power Supplies

Modern arcade builds almost exclusively use switching power supplies. They are smaller, lighter, more efficient, and generate less heat than linear supplies. Linear supplies were common in vintage cabinets but are largely obsolete for new builds.

ATX vs Dedicated Arcade Power Supplies

For PC-based MAME cabinets, an ATX power supply is often the best choice. For original arcade hardware, a dedicated arcade switching power supply with the correct voltage outputs is essential. ATX supplies can be adapted using breakout boards, but this adds complexity.

Safety Certifications

Look for UL, CE, or ETL certifications, especially for cabinets that will be used in public spaces or around children. Certified power supplies have passed rigorous testing for electrical safety and fire resistance.

FAQs

Conclusion

Choosing the right power supply is one of the most important decisions in any arcade cabinet build. For most builders, the Mean Well LRS-350-24 offers the best combination of reliability, capacity, and safety certifications. Budget-conscious builders should consider the Arcity triple output for versatility or the RetroArcade 16A for simple JAMMA compatibility. PC-based MAME builders will find the Thermaltake Smart 700W paired with an ATX breakout board to be a solid foundation.

Whatever power supply you choose, always measure voltage at the board edge, not at the power supply terminals. A stable +5V rail is the key to reliable arcade operation. Take the time to do it right, and your cabinet will provide years of trouble-free gaming.
