Understanding the power consumption of arcade machines is crucial for collectors, operators, and enthusiasts, whether for budgeting electricity costs, ensuring proper circuit capacity, or general curiosity. The power draw of an arcade cabinet is not a single fixed number; it varies significantly based on the era of the machine, its components, and its operational state.

A primary factor influencing power use is the technology generation. Classic arcade machines from the Golden Age (late 1970s to mid-1980s), featuring vector or standard raster monitors and simpler PCB boards, are surprisingly efficient. A typical machine like *Pac-Man* or *Donkey Kong* consumes between 150 to 300 watts during active gameplay. The large cathode-ray tube (CRT) monitor is the most power-hungry component, accounting for roughly two-thirds of the total draw.

Later-era machines, particularly those with larger CRTs, more complex audio systems, and elaborate lighting (e.g., *Street Fighter II* pinball machines), see higher consumption. These can range from 300 to 600 watts or more. Pinball machines are especially notable for their higher draw due to solenoids, coils, and numerous lights, often averaging between 300 to 450 watts and spiking significantly during multiball sequences.

Modern arcade machines, often using LCD/LED screens and more efficient computer-based systems, tend to be more economical. A contemporary arcade racer or shooter with a large LCD might use 150 to 250 watts, similar to or less than a classic cabinet.

It's important to note that a machine's idle state—where it is powered on but not in active play (attract mode)—draws only slightly less power, as the monitor and core systems remain active. True energy savings only come from completely turning the unit off.

For accurate measurement, using a plug-in power meter is highly recommended. This provides real-world data specific to your cabinet, accounting for component age and efficiency losses. When planning your arcade room's electrical layout, always calculate based on the highest potential draw to avoid tripping breakers.
