When buying a new PSU you must consider several things, including the brand. Simply put, there are good PSU’s and bad power supplies. It just so happens that most of the good ones fall in the same group of brands, where most of the bad computer power supplies fall in a different group of brands. This results in a list of bad and good brands when it comes to your computer power supply. If you want to avoid destroying your computer due to a bad PSU, or want to buy something that will last longer than a year, you may want to spend the few extra bucks and get a AAA brand PSU instead of the cheapest one available.
PSU brands – which to avoid and which are great!
When you look at problems people tend to have with their power supply you see certain brands pop up a lot more than others. In addition, these brands tend to come up as well when you look at PSU’s failing after a year or something comparable.

Besides avoiding certain brands of PSU’s or looking at quality brands for computer power supply units there is more to it than that. Power supplies can get certificates which show you just how well they perform consumption wise. A power supply tens to lose some of its power to heat, thus resulting in more power consumed than put to good use. This is where the certificates come in.
As said before, power supply units tend to lose some of its power to heat production. This results in less power put to good use compared to the power that is drawn from your socket. PSU certifications show you just how well your PSU should perform.
Power Supply Unit efficiency
There are several different kinds of certifications for PSU’s. The normal 80 PLUS certification means that a certain PSU efficiently uses 80% of the power consumed at 20% load, 50% load and 100% load. Every PSU loses power to heat and 80% efficiency is actually pretty good. There are of course power supplies that go over the 80% and those gain other certificates. In all there are 6 kinds of 80 PLUS PSU certifications to be had, where each they all indicate a certain degree of efficiency of the power supply unit.
PSU Certification standards
As you can see it goes up all the way to over 90% efficiency, which is pretty incredible, but is not that much of a necessity for the average consumer. Anything with an 80 PLUS certification or 80 PLUS bronze should do more than well for your computer and basically tells you that you are buying a decent PSU.
Besides efficiency there are of course more things to look at when buying a power supply unit. One of things is a modular design.
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.
The first thing you should look at is the amount of power your computer will be consuming, and attune your power supply unit to that number. To find out the power needed you can look at each individual component and find out how much power they consume, or use one of the several online tools to get a good estimate. Asking an expert is of course usually best, especially if you are pretty new at this. Although more power ensures your computer of the needed power, it is unwise to go too far above your needs, since this will cost you more money when buying the PSU, as well as in the electric bill in the end. I have a pretty high end system with a hexa-core processor and a very decent graphics card, several hard disks and enough memory to make it all run smoothly and I am only using a 550 Watt power supply unit.
The second thing to keep in mind when buying a new computer power supply unit is the brand you are buying. There are several brands you should avoid. On the flipside: there are a lot of brands known for their quality products and long lasting PSU’s. Here is an overview of quality power supply unit brands.

The third thing to keep in mind is wether you have or need all the connections on a PSU. Make sure you can connect all your components using the proper cables and connectors, and minimize the amount of cables not used. For an optimal effect you may consider buying a modular PSU.
Besides all this, you can also choose for a power supply unit with built in lights to create certain effects in your computer case, but this of course totally optional.
I hope this information was helpful for those about to buy a PSU and you will make the right choice for your computer’s power supply unit.
