So we have discussed some brands to avoid and some brands to definitely consider when buying a power supply unit as well as some certifications modern PSU’s should have, but besides that is of course also something as usability. A very important factor for any PSU is that it should have all the connections your computer needs. Every basic PSU has connectors for your motherboard, a harddisk and an optical drive, but if you are using a lot of different expansion slots – like an advanced graphics card – you better make sure it has the connections needed for that card. Modular Power Supply Units can help you there.
What are Modular Power Supply Units?
With standard PSU’s all cables are attached to the unit at all times. If you are not using some of those cables they are just hanging there, cluttering your case and reducing your airflow. For basic users this is not a big problem, but for the more advanced users this can be very annoying. Another annoyance can be upgrading. When you buy new components and find out that your PSU does not have any free power cables for that specific component anymore, you can basically buy a new power supply unit. There is however a solution for these problems; Modular Power supply units.
Modular PSU’s only feature the basic elements permanently, like a cord for your motherboard. The rest of the wires are optional and can be freely switched in and out. This removes unnecessary cables in your computer case, and allows you to switch cables when your need for connections changes. These modular PSU’s usually are bit higher prices, but that small amount of extra cost can sure make a big difference.
Getting a modular PSU or a regular power supply unit is something to keep in mind when buying a new PSU for your computer.
To get an overview of what to consider when buying a new power supply unit I took the liberty of writing a quick summary on the different aspects of buying a PSU – read on to find out more.
