Power Cost for a Home CPU or GPU Mining Rig

A worked example for calculating the electricity cost of mining Malairte on a normal household setup.

Time-of-use electricity plans and when to mine Malairte

Many utilities charge two or three different rates depending on the hour. Scheduling your miner around those windows can cut your effective electricity cost in half.

Measure your rigs actual power draw with a Kill A Watt

Why the wattage on your power supply label is not what your mining PC actually uses, and how a $25 plug-in meter gives you the real number you need to budget electricity.

Reading your electricity bill to find your true mining kWh rate

The headline price on an energy ad is rarely what you actually pay per kWh. Here is how to dig your real, all-in rate out of a confusing utility bill so your mining maths is honest.

Heat output: using your mining rig as winter space heating

Every watt your mining PC consumes becomes heat in the room. In winter that heat offsets your furnace or electric heater, which changes the real cost of mining.

Power supply efficiency ratings and the watts you waste

Your PSU quietly throws away some of the electricity it pulls from the wall as heat before your components ever see it. Understanding 80 PLUS ratings tells you how much, and when an upgrade pays back.
