Arcade game machines, whether classic or modern, consume varying amounts of power depending on their design and components. The most common power consumption metrics include:

1. Wattage (W) – Measures the active power draw of the machine during operation. Older CRT-based arcade cabinets may use 300-600W, while modern LCD-based units often consume 150-300W.

2. Voltage (V) & Amperage (A) – Standard arcade machines typically operate at 110V or 220V, with amperage varying based on load. A higher voltage setup may reduce current draw.

3. Kilowatt-hours (kWh) – Used to estimate long-term energy costs, calculated by multiplying wattage by hours of operation.

4. Standby Power – Some machines draw 5-20W even when idle, contributing to "vampire power" loss.

5. Energy Efficiency Ratings – Newer models may feature certifications like ENERGY STAR, indicating lower power consumption.

Factors like screen type, lighting, and additional peripherals (e.g., coin mechanisms) also impact overall energy use. Understanding these metrics helps operators optimize electricity costs and maintain sustainable arcade setups.
