When most of the people choose a PC, they tend to focus on those parts which have a lot of curb appeals, such as processors or graphics cards, but for some reason, they tend to forget about the less flashy components. It is quite evident as nobody would get too excited when a slightly more reliable & efficient power supply hits the market, but it is important to understand how crucial it is to have a quality PSU for your computer. While building or customizing a computer, you should do a little homework to ensure that you get the right power supply for your system. To determine what you should be looking for in a power supply unit, you should take the following things into consideration:

Wattage

The most important thing that should be considered is how much wattage a system will require. In situations like this, more isn't always better. While it is imperative that a PSU provides sufficient power for all the components when they are under heavy load, if you go overboard, your system can be less efficient while doing tasks that aren't CPU or GPU intensive. Most of the power supplies hit their peak efficiency between 40-80% of a PSU's maximum capacity. We suggest building to about 60% of the power supply's capacity for hitting the sweet spot for efficiency while leaving some headroom for future upgrades.

The exact wattage that a computer will require depends upon the components you decide to choose for your build. Higher-end processors & graphics cards require a lot more power than their low-end counterparts. So, for determining exactly how much juice you'll need, you can select your individual components and figure out exactly how much power your system will require, you can also take the help of a power supply calculator for calculating it.

Efficiency

The efficiency rating of the power supply is essential because higher-efficiency units usually have better components, waste less power, and generates less heat; all of these contribute to less fan noise. A power supply that has an efficiency rating of 80 percent will provide 80 percent of its rated wattage as a power to your system while losing the remaining 20 percent as heat.

Cable Management

You'll have to choose whether you would want to have a modular Power Supply Unit or not. Modular power supplies are popular mainly because they enable the user to easily & simply organize your power connections. With the standard power supplies, there are always unused cables that you will have to bundle up and hide somewhere inside the case; doing this can be unaesthetic and can interfere with the airflow in smaller cases.

However, the modular PSUs come with their own set of drawbacks. Each connection can increase the impedance on the circuit, which potentially makes it less efficient. While the Modular PSUs have improved over time, the connection can never be as efficient as a straight wire. However, for most users, the ability to have a clean and tidy looking computer outweighs the slight drop in the efficiency.

Quality

This is one of the most crucial things that should be considered while purchasing a power supply. When you buy an inexpensive PSU, you can save money in the short term, but if you skimp on the quality, it may lead you to run into a lot of issues later. Thus, a quality power supply will last the entire life of your computer. Therefore, it is suggested that you should do your homework and pick a premium brand while buying a power supply.
