How To Choose The Right PSU For RTX 4090

Investing in a Power Supply Unit can be a bit tricky and confusing at the same time. You can be overwhelmed by the unwanted overthinking that comes with buying a PSU. However, if you keep a check on the following factors, you will be able to prevent these common headaches that come during the buying process of a PSU.  

Wattage

If you haven’t figured out the required wattage of your system, you better don’t embark on the mission of buying a PSU for your system. It is quite obvious that you are supposed to know how much wattage is that you should go for. The wattage requirement directly depends upon the type and number of components your system carries. For example, a mid-level system with conventional components will require lower wattage than a high-end system with tons of latest-generation components. Now what you have got to do is take a look inside your system and make a list of all the major components. Once you are done listing them, Google the wattage requirement of each major component and you will get your answer. If you are a lazy creature who doesn’t like to do calculations, go for a PSU with a wattage of more than 650W as a bare minimum. This will cover your system against the future-upgrades and would allow you to utilize power-hungry hardware without trouble. This includes RTX 4090 and other latest generation Graphics Cards from Nvidia and AMD. 

Protection

We bet, there is no replacement for a PSU with a power protection mechanism. A good PSU is one that can do well against common power-related issues. In other words, the PSU should have a proper power protection mechanism against over-voltage and under-voltage. And not only that, it should be good enough to provide protection against several other power-related issues including over-power and short-circuit. Protection comes as the primary requirement for a PSU designed for a high-configuration system. Trust us on that, there can be no debate about bypassing it. 

Efficiency

The right PSU prioritizes an efficient supply of power over anything else. It doesn’t make any compromise on efficiency at all. A PSU with an inefficient power supply causes heat issues that negatively impact the health of your system. As a result, it reduces the lifespan of critical components. Therefore, you should only settle for a PSU that guarantees an efficient power supply. If you are wondering how to figure out the efficiency of a PSU, worry not. All you should do is take a look at the PSU box and see if it has 80 Plus Certification on it. For your consideration, 80 Plus means that the PSU supplies power with 80% of efficiency. An efficient PSU is all about using less power and generating less heat. 

Form Factor

Don’t waste your money on buying a PSU that takes a great amount of effort to fit into the PC chassis. In short, invest in a PSU  that doesn’t make it a puzzling process for you to install it into the system. It should feature the kind of size that allow for extra room for other components. An oversized PSU will affect the functionality of your system. Apart from leaving limited room for the hot air to exit, It might damage other components during the installation and ejection process. Generally, most PC users go with the standard ATX form factor. However, this doesn’t mean that you should follow in their footsteps. Instead, learn about the form factor of your chassis and go for the PSU form factor accordingly.
