Why turn it OFF?

Save Energy

An average PC consumes 100 W of power while on - just like a light bulb. Let's say electricity costs an average of 20 cents per KWh in Australia. By turning your computer off for 12 hours a night, you would save 12 hours x 20 cents x 0.1 KWh = 24 cents per day. That's a total of $7.20 per month.

Safer from Hacker Attacks?

If you worry at all about internet security, then you already know that if your computer is off, it cannot be hacked or infected with malware. Nevertheless, malware is frequently seeded when you are actively using your computer and is activated when you restart your computer. The benefit of shutting down your computer for security is quite questionable.

Why leave your computer ON?

Download Torrents or Large Files Faster

If you are in Australia and downloading torrents or large files, you may want to leave your computer on. Here are a few reasons why:

  • Torrents are downloaded from other torrent users' computers, known as peers. Both your computer and your peer's computer must be on. The more peers you have, the better download speed you get. Let's say someone seeded (uploaded) a movie in the US - it will likely be better available during the late afternoon across US time zones when Americans are sitting at home with their computers on. That means you will want your computer in Australia to be on during the early hours of Australian daytime.
  • Some Australian internet providers offer free, unlimited night traffic on certain accounts.
  • Networks are less congested at nighttime.
