One of the most persistent misunderstandings in home mining is a unit error. People hear "mining draws kilowatts" and picture their electricity meter spinning into the red. For a home Malairte rig, the honest figure is usually a few hundred watts - and the difference between hundreds of watts and kilowatts is the difference between a household appliance and an industrial machine.

Getting the units straight

A watt is a unit of power. A kilowatt is a thousand watts. The leap from one to the other is exactly the leap from a home PC to a small industrial load:

  • Hundreds of watts: a desktop, a games console, a microwave mid-cook, a hairdryer on low.
  • Kilowatts: an electric oven, a tumble dryer, a domestic heat pump, an industrial mining ASIC.

A home Malairte rig lives firmly in the first group. A CPU-only build sits around 90-180W; add a GPU and you reach 250-450W; a serious two-GPU rig might touch 900W. Only the largest home setups approach a single kilowatt, and most never get close.

Where the confusion comes from

Industrial Bitcoin mining genuinely operates in kilowatts and megawatts - a single ASIC pulls 3,000-5,000W, and farms stack thousands of them. News coverage of those farms uses kilowatt and megawatt language correctly, but the framing bleeds into conversations about all mining, including the home CPU and GPU mining that Malairte is built around. The units that describe a warehouse of ASICs simply do not describe a desktop in a spare room.

Putting a home rig in context

A 400W rig running continuously uses about as much energy as leaving a few old-style light bulbs on, or running a modest fish tank with heater and pump. Over a month at typical rates it costs in the region of a streaming subscription or two. That is a real cost worth measuring and managing, but it is not the grid-straining figure the word "kilowatts" conjures.

Why the distinction is useful

Keeping watts and kilowatts straight is not pedantry - it changes how you reason. When you know your rig is a few-hundred-watt device, you compare it sensibly to other appliances, you size meters and plugs correctly, and you tune for efficiency rather than panicking about scale. The single misplaced "kilo" is responsible for a surprising amount of the fear around home mining; remove it, and the whole picture becomes calm and manageable.
