Arcade game machines rely on various power supplies to ensure smooth operation and longevity. The most common types include:

1. Linear Power Supplies: Traditional and simple, these provide stable voltage but are less efficient and generate more heat.

2. Switching Power Supplies (SMPS): Modern, compact, and energy-efficient, these are widely used in newer arcade cabinets.

3. ATX Power Supplies: Adapted from PCs, these offer multiple voltage outputs and are popular in custom or multi-game arcade setups.

4. Transformer-Based Power Supplies: Found in vintage arcade machines, these use heavy transformers for voltage conversion.

Each type has pros and cons, with SMPS being the most versatile for contemporary arcade gaming needs. Proper selection ensures optimal performance and prevents hardware damage.
