Leaving your PC on all night to farm: is it bad? How much does it cost? How to set it up

Updated · 5 min read · by IdleDeck

Summary
  • Computers are made to stay on: what shortens their life is heat, dust and power surges, not the hours.
  • Electricity bill: watts × hours ÷ 1,000 = kWh. An 80 W PC left on 24 hours a day for 30 days uses about 58 kWh.
  • In Windows, let the screen turn off, but set sleep to "Never" when plugged in, and adjust Windows Update's active hours.
  • With the PC asleep, nothing runs. IdleDeck keeps your accounts awake, reloads a page that goes down and alerts you when one needs you.

Is it bad to leave your PC on 24/7?

Not because of the hours it is on. Servers run for years without shutting down, and the parts of a regular PC can also handle long hours of use. What shortens a computer's life is something else:

  • Heat and dust. A clogged fan and a case with no airflow make the parts run hot all the time. Farming an idle game is a light load, but a constant one.
  • Power surges. The power going out and coming back, lightning near your home. A good surge protector or a UPS protects better than turning the PC off at night.
  • A laptop that cannot breathe. Plugged in all day, it runs hotter: keep it on a hard surface (never on the bed) and, if the manufacturer offers it, turn on the mode that caps the battery charge at around 80%, which extends the battery's life.

How much electricity it uses

The math is simple: power in watts × hours on ÷ 1,000 = kWh. Then multiply by the price per kWh shown on your electricity bill (with taxes and fees, it varies from region to region). On 24 hours a day for 30 days, that's 720 hours a month:

Computer (no monitor)Draw while farmingkWh per monthAt US$ 0.20/kWh
Laptop or mini PC15 to 30 W11 to 22 kWhUS$ 2 to US$ 4
Office PC40 to 70 W29 to 50 kWhUS$ 6 to US$ 10
Gaming PC with a graphics card80 to 150 W58 to 108 kWhUS$ 12 to US$ 22

These are example ranges: the real draw depends on the parts, on how many accounts are open and on the game. The right way to know is to measure it with a plug-in power meter (or a smart plug that shows energy use) during a day of farming. A monitor that stays on adds another 15 to 30 W — letting the screen turn off by itself is the easiest saving.

Windows settings for farming all night

  1. The screen can turn off; the PC must not go to sleep. In Settings › System › Power (on a laptop, Power & battery), in the screen and sleep section, let the screen turn off after a few minutes and set sleep to Never when plugged in. With the PC asleep, no tab runs.
  2. Hibernation stops everything too. If there is an option to hibernate after a while, set it to Never while you farm.
  3. Windows Update on your schedule. In Settings › Windows Update › Advanced options, set your Active hours to cover the period when the PC farms on its own: Windows avoids restarting to install updates during that window. You can also pause updates for a while before an important night.
  4. Laptop with the lid closed. In Control Panel › Power Options › Choose what closing the lid does, choose "Do nothing" for when it is plugged in — otherwise closing the lid puts it to sleep.
  5. Power mode. Balanced does the job. Windows energy saver, when on, limits what runs in the background.

Precautions worth taking

  • Clean the dust off the fans every now and then and give the case room to breathe.
  • A small UPS keeps the PC running through a brief power outage, so the farm does not stop. A long outage shuts everything down, with or without it.
  • Keep open only what you need: each account is a game page running, and more accounts = more power use.
  • Check each game's rules about leaving the account on: some ban tools that keep the session active.

Where IdleDeck comes in

A PC that stays on is half the job; the other half is keeping the tab from falling asleep. IdleDeck keeps each account awake with the window minimized or in the tray and reloads on its own any page that goes down. With the option to start with Windows, it opens by itself after a restart and turns back on the accounts that were running. If the game connection drops or an account needs attention, it alerts you by Windows notification, sound or Discord — on your phone, if you use the webhook.

Common questions

Can I leave my PC on all night?

Yes. Computers can handle long hours of use; what really wears them out is heat, dust and power surges. Keep the vents clean and use a good surge protector or a UPS.

How much does it cost to leave a PC on 24/7 for a month?

Multiply the power in watts by 720 (the hours in a month) and divide by 1,000 to get kWh; then multiply by the price per kWh on your electricity bill. An 80 W PC comes to about 58 kWh — around US$ 12 at US$ 0.20 per kWh.

Does turning off just the monitor save power?

It does: a monitor uses 15 to 30 W, and turning off the screen does not stop anything on the computer. That is different from sleep, which stops everything.

Can Windows restart by itself during the night?

It can, to install updates. Active hours, under Windows Update › Advanced options, tell Windows when not to restart; you can also pause updates for a while.

Do sleep and hibernation stop the game?

They do. With the PC asleep or hibernating, nothing runs — not the browser, not IdleDeck. To farm, set sleep to "Never" when plugged in.
