UPS Advice

Power Supply Unit failure (PSU) failed can ruin your day. An Uninterruptible Power Supply (UPS) can save it.

An Uninterruptible Power Supply (UPS) is a device that keeps your PC or Mac running in the event of a power cut, or power fluctuation, by switching over to battery power.

In an ideal world, you should aim to get a UPS with 20 minutes of battery time. This is determined by the size of the battery and the power usage of the equipment you plug into it.

A small 400VA (Voltage/Amps) unit, as demonstrated in the video, will run your average PC or Mac for around 12 minutes. The idea is that, in the event of a power cut to your home or office, the UPS will keep the computer running for long enough to save your work and shut it down.

Whilst power cuts are rare, power supply fluctuations are much more frequent. Often these go unnoticed because we see no evidence. Only in a severe case do you see the lights dim slightly.

This is known as a brown-out. It places undue stress on the PSU (Power Supply Unit) inside your computer and typically they will blow. Result – Day ruined ! Especially if you are in the middle of something urgent that must be sent off in
5 minutes.

A UPS can save the day. If you buy the right type, they can give you 20 minutes for battery backup, or longer. Remember to plug your router into a UPS and any network switches into them too. Nothing worse than having a PC stay on but the internet goes off!
