How-To

Size a UPS and surge protector for a home mining rig

A mining rig runs unattended for hours, so a power blip can corrupt a wallet sync or cook a component. Here is how to choose a correctly sized UPS and surge protection without overspending.

Undervolt your GPU to mine Malairte more efficiently

Lower the voltage on your graphics card to cut power draw 20-30% with only a small hashrate hit. Step-by-step for NVIDIA and AMD on Windows.

Calculate your daily mining cost at your own kWh rate

A simple three-number formula that gives you a defensible daily electricity cost for any home Malairte rig. Includes worked examples at different US, EU, and UK rates.

Cap your CPU power limit in Windows to cut mining watts

You do not need to undervolt to tame a hot, thirsty CPU. Windows power plans and a couple of BIOS settings let you cap processor draw, trading a little hashrate for cooler, cheaper mining.

Set up a smart plug to log your mining rig power use

A $15 energy-monitoring smart plug turns your phone into a permanent wattage logger, so you can track daily kWh, spot wasted idle hours, and cost mining at your real rate. Full setup walkthrough.
