How much does a 230 W gaming laptop cost to run? Desktop vs laptop power
A 230 W gaming laptop running 4 hours a day at 80% utilization costs about $48.36 a year at $0.18/kWh, $4.03 a month and 269 kWh annually. That's less than half what a comparable-performance 500 W gaming desktop costs to run on the same schedule, entirely because of mobile silicon's lower power budget.

How this is calculated
Laptop peak wattage is bounded by the AC adapter: a 230 W brick means the laptop can't sustain more than 230 W regardless of workload. In games, a 230 W gaming laptop typically pulls 180-210 W from the wall. It's a real-world cap that mobile GPUs are deliberately binned around. On battery, performance drops sharply (often 30-40%) because the platform self-limits to preserve runtime, so the meaningful electricity-cost figure assumes plugged-in use.
Verdict
$48 a year for mobile gaming is genuinely cheap. The watt-hours of a full evening's session work out to pennies. If electricity cost mattered more than portability, a matched-performance desktop would use about twice as much.
