8 Best PSUs for RX 6700 XT in 2021

The RX 6700 XT is the latest example of RDNA 2 graphics card architecture and one of the most affordable mid to high-end GPUs out there. With AMD’s innovative Infinity Cache, a large memory, and impressive clock speeds, this GPU is a solid next-gen piece of hardware that you want to have in your new system. However, you’ll also need a powerful and reliable power supply to go with it. So, let’s discover the 8 best PSUs for RX 6700 XT.

RX 6700 XT PSU Requirements

According to AMD, the RX 6700 XT requires 230W on its own. That means you’ll need at least a 650W power supply. However, this depends on your overall PC configuration, especially the CPU. If you decide to go with a powerful processor and overclock your GPU, you should aim for a 750W power supply instead. It’s always better to have some headroom than to push your PSU to its maximum capacity regularly.

That being said, we’re going to explore a series of 650W to 750W of power supplies for every budget. Let’s get started!

Best PSUs for RX 6700 XT

This PSU is entirely modular and is quite small for the amount of power it provides. Cable clutter is a thing of the past and you no longer have to break the bank to afford this feature. Corsaire is one of the manufacturers that brought several premium features to the mainstream market.

The RM750x comes with all the connectors you need for your setup and more. You’ll find that there are more than enough peripheral connectors and four-pin Molex connectors. We’re happy to see that versatility and adaptability are something that Corsair still focuses on.

All in all, the RM750x is one of the best power supplies you can purchase if you’re looking for a reliable modular PSU without any expensive luxury-features.

It’s not very efficient, having a White efficiency rating, and you will feel that when the power bill comes in. On the plus side, it comes with a 5-year warranty, so despite its simplicity, it’s a fairly reliable piece of hardware.

Furthermore, there’s no modularity to speak of. All connectors are permanently attached to the body of the PSU, so you’ll have a hard time managing your cables to ensure adequate airflow.

Overall, Thermaltake’s Smart 700 is a simple power supply that powers your computer and protects it from short circuits, power fluctuations, under-voltage, and over-voltage. If you don’t mind a higher power bill and you have plenty of room in your PC case to arrange the cables, this PSU will do its job.

If you’re on a tight budget, AGV750 from Aresgame might be the PSU you’re looking for. This power supply offers 750W of power with a Bronze efficiency rating. That’s more than enough juice for the RX 6700 XT, and 85% efficiency isn’t that bad. What’s important is that it provides your system with reliable power that doesn’t fluctuate and it comes with all the standard protections you expect from a modern PSU.

In addition, the AGV750 is semi-modular, so you can remove most of the connectors you don’t need to provide your case with good airflow. The cables are comfortably long, so you can easily route them without being forced to choose the shortest distance between components. This will further improve airflow and keep the cables from just hanging over the hardware.

That being said, this power supply comes with a fairly short warranty period of 3 years. This doesn’t look good when it comes to durability. However, it’s a budget power supply that you will probably replace in a few years with something more efficient.

All in all, the AGV750 is powerful enough to support your RX 6700 XT system and cheap enough to ignore some of the features it lacks, such as full modularity.
