Malairte Mining Energy: Resources and Tools

For a single home PC, no - the increase is typically a few dollars to a few tens of dollars per month, similar to leaving a gaming session running. Multiple cards or a dedicated rig will draw more, but Malairte mining is fundamentally household-scale, not industrial-scale.

A single CPU-only desktop mining flat out usually pulls 90-180 watts from the wall. Add one GPU and you are looking at 250-450 watts. A dedicated two-GPU rig sits at roughly 600-900 watts. Laptops are much less, often 35-90 watts even at full load. These numbers are an order of magnitude smaller than industrial ASIC operations and roughly comparable to running a desktop game for the same number of hours. The only way to know your exact figure is to measure with a plug-in energy meter; nameplate PSU wattage is the maximum the supply can deliver, not what your computer actually draws.

Per watt, modern laptops are usually more efficient than desktops because their mobile CPUs and integrated GPUs are tuned for battery life. A laptop pulling 65W can mine respectably while costing only $5-8/month in electricity at typical home rates. A desktop pulling 350W earns more MLRT but costs five to seven times more to run. If your goal is to mine "for free" alongside normal computer use, a laptop is hard to beat. If you want to maximise hashrate per dollar of hardware, a desktop with a dedicated GPU wins. Laptops also have weaker cooling, so prolonged 24/7 mining can stress the keyboard and battery - many laptop miners run only 8-12 hours per day.
