finding the best Power Supply is essential for any modern computer system. They provide stable and reliable power to all the other components, ensuring that your system runs smoothly without any hiccups. While there are plenty of good PSU options for building affordable sub-$1000 gaming PCs, it’s important to take extra care when building high-end and enthusiast systems to ensure you get an ample amount of power going to those thirsty CPUs and graphics cards.
If you are thinking about building a new system featuring an RTX 4090 graphics card, then an 850W PSU should be all you need, although, we recommend buyers take a look at 1000w PSUs to protect their investment for longer too.
Do you need an 850W PSU?
An 850W PSU is quite a lot of juice for any builder, so you need to make sure you are going to use it, even if it is a few years down the road. Hardware is always getting more and more powerful but very few actually require 850 watts. As we mentioned, if you are building a high-end PC then there is nothing to worry about, however, if you are on a strict budget and are going to wait for a few more years till you bag an RTX 4090, then double check what you need with a PSU calculator.
