Two Speaker System

This system consists of two simple speakers that are compact and easily sit on your computer desk. They only consume very less power within 10 to 15W. The playback will be decent and it is useful for office usage. If you aren’t very concerned about the audio quality or loudness, you can go with this speaker system.

2.1 Speaker System

This is a set of two speakers with a sub-woofer setup. There are several models with higher watts consumption. But the starting model of such speakers might consume about 25W and it can go up to 100W. Those who are concerned about audio quality and want a slightly better listening experience, then they can choose this system.

5.1 Speaker System

This is the most suitable system for PCs which can provide the best listening experience despite the mode of usage. The watts consumed at the minimum is around 75W and you can also get powerful systems that consume more than 300W. You will have five speakers and a subwoofer. You can set the speakers in a surround system and get high-quality listening.

7.1 Speaker System

This is usually overrated for a PC system. But if you are a content creator or a video editor, it might be useful. The watts required is more than 500W and it comes with 7 speakers along with a subwoofer. It is also slightly pricier than other models.


Instead of getting a separate speaker system for your computer, you can buy a compact yet powerful soundbar. It is a bar that is quite long and sits compactly on your computer desk. It consumes around 100W and there are more powerful soundbars too. It is more effective than a 2.1 system and a two-speaker system. It can also last longer than them.  With premium models, you can get surround sound too.

Bluetooth Speakers

This is usually not used with PCs. But you can find some models for computer systems. If your motherboard has a Bluetooth card, you can easily use this option. There is a wide range of models available, but the minimum of them consumes around 50W.

Powered Speakers

This can also be a slight overkill for your PC setup. Because along with the surround speaker system, this model uses an amplifier to increase the sound output. The power consumption skyrockets to more than 700W. It is not generally used by common audiences.

These are the different types of speakers that can be used for computers and their respective watts usage.

Why is PC speaker Wattage important to notice?

The wattage rating of the speakers denotes the output and audio quality. The higher the wattage, the better and more powerful will be the output. For instance, if you are using a basic two-speaker system with your PC, it consumes only 10W.

The audio quality and loudness will be very less. At the same time, if you are using a 5.1 channel surround system, it consumes more than 200W and you will get powerful bass and higher audio quality.

When you have a higher wattage rating, the characteristics of the sound are expressed more clearly. If you want to have detailed hearing with DTS-like quality, then you have to get a higher watts speaker system.

When you go with high-quality speakers, you will have several speakers that produce surround audio output. This makes the listening experience deeper and more intimate. So, if you want to get high-quality listening, then you should notice the wattage of the speaker.
