Idle vs load power: what matters

Two different duty cycles, two different bills.

A simple split

Example: 50W idle × 22h and 300W load × 2h. Idle energy can exceed load energy. Always-on render boxes are different from nightly gamers.

What to change first

If idle dominates, fix power management before buying a new PSU. If load dominates, look at power limits and undervolt savings sketches.

FAQ

Can idle cost more than gaming?

Yes if the PC is on 24/7 and you only game a couple hours.

What cuts idle?

Sleep/hibernate, efficiency modes, shutting down.

What cuts load?

Frame caps, undervolt, lower power limits — with stability testing.

Does WattFit model both automatically?

The main tool models the load hours you enter. Model idle as a second pass.
