Arcade machines rely on efficient power supply configurations to ensure smooth gameplay and longevity. The most common setups include:

1. Linear Power Supplies: Traditional and simple, these provide stable voltage but are less efficient and bulkier. Ideal for classic arcade cabinets.

2. Switching Power Supplies (SMPS): Compact and energy-efficient, SMPS units are widely used in modern arcade designs due to their lightweight and adjustable voltage outputs.

3. ATX Power Supplies: Borrowed from PCs, these offer multiple voltage rails (e.g., +12V, +5V, -5V) and are popular for custom or multi-game arcade setups.

4. JAMMA Standard Power: Follows the JAMMA wiring harness specification, providing +5V, +12V, and -5V for compatibility with most arcade PCBs.

5. Battery-Backed Systems: Used in portable or redemption machines, these combine rechargeable batteries with AC adapters for uninterrupted power.

Each configuration has trade-offs in cost, efficiency, and compatibility, so choosing the right one depends on the arcade machine’s design and hardware requirements.
