Best PSUs for RTX 3070, RTX 3080 & RTX 3090 in 2022

Nvidia Ampere GPUs are here, selling in three flavors. The Ampere architecture isn’t very power efficient, at least when it comes to gaming models. While the RTX 3070 has about the same TDP as its direct predecessor, the RTX 2070 Super, both the RTX 3080 and RTX 3090 go above and beyond the power requirements of the last gen’s flagship, the RTX 2080 Ti.

Combine a power-hungry GPU with a power-hungry CPU such as the Core i9-10900K or the Ryzen 9 3950X and you get a gaming system that can need almost 550W of power during certain loads. That high of a power draw demands not only a powerful PSU but also a quality one that can deliver the power written on the label at all times, even going beyond the official specs during short power spikes.

Today, we will show you the best power supplies you can (and should) get for the RTX 3070, 3080, and 3090. While the bulk of the list is made out of ATX PSUs, we’ve reserved a small portion of the article for SFF power supplies. You can find it at the bottom of this text. When it comes to the price yes, PSUs are still greatly overpriced and it seems this could be the new normal for PSU prices. So, if you want to wait for power supplies to return to their pre-pandemic prices, you might have to wait for a long, long time. Anyway, let’s begin.

Best power supplies For RTX 3070

The RTX 3070 has a TDP of 220W, just 5W more than the RTX 2070 Super. Since Nvidia promises RTX 2080 Ti-like performance, 220W isn’t too bad. The official power requirement found on Nvidia’s site states a minimum of 650W of power, but the reality is that you could be completely fine even with a less powerful PSU.

1. be quiet! Pure Power 11 CM: Best budget 500W PSU for RTX 3070

The minimum power you need to run the RTX 3070 should be about 500W. That’s in case if you have a 65-75W CPU. Together, the whole system should peak at about 350-370W, which means even a 450W PSU could be fine. But, just to be safe, we recommend a minimum of 500W. If you have a beefier CPU or an overclocked R5 3600 for instance, you should get a 550W PSU, just to be safe.

Some of our recommendations include budget, non-modular models such as the EVGA 500 GD. It’s a decent PSU but if you want something modular, check out the be quiet! Pure Power 11 500W CM. It has an 80Plus Gold certificate as the EVGA one, but also a semi-modular design that should make installing it easier.

Something a bit more expensive but also of higher wattage and quality is the Corsair CX550. It’s only Bronze certified but the CX series as a whole is pretty good. The CX550M, an upgraded version of the base CX model, is another excellent pick. You also have the Cooler Master MWE 550, which is another pretty good PSU for the money.

5. Corsair CX650M: Best budget 650W PSU for RTX 3070

If you want to get a PSU that will be powerful enough for future builds, or in case you own something like the overclocked 9900K, 10600K, or the 3900X, you should aim for a 600-650W power supply.

The RTX 3070 demands far less than a 750W PSU, even when coupled with something like the 5.1Ghz 10900K. But if you have cash and are ready to spend a bunch of money on an overkill PSU, get a 750W power supply. It will be enough in case you get a more powerful graphics card, even something like the RTX 3090, and it will work fine with any consumer-grade CPU.

Best power supplies For RTX 3080

As you can see, the RTX 3080 can work fine with a quality 600W power supply, even when paired with an overclocked 10900K. We wouldn’t recommend a 600W PSU for the long run in case you do have an OC 10900K paired with the RTX 3080 but in case you rock something like the 10600K or the 3900X even a 600W power supply should have no issues with running the system.

Minimum – 600-650W

Now, the minimum wattage for being completely safe no matter your CPU is 650W. This way you have some headroom in case you have an RTX 3080 model with a higher power limit (despite the base TDP of 320W, some RTX 3080 models can go well over 400W when overclocked and under a max load). For the full list of recommended power supplies just scroll above and ignore the budget picks.

In case you want some headroom for a future upgrade or just want to be safe and sound, a 750W power supply should be more than enough. This will allow you to overclock the hell out of any CPU and any RTX 3080 card without a pinch of worry will power supply handle your overclocking hobby. A 750W PSU should also be powerful enough for any kind of future upgrade sans getting dual RTX 3090s to use in an SLI setup. Again, you can find the list of the best 750W picks above.

14. Corsair RM850: Best budget 850W PSU for RTX 3080

Now, if you have money to burn or if you want a 100 percent futureproof PSU, get an 850W model. These are way overpowered for the RTX 3080 and any consumer-grade CPU but if you’re rocking a Threadripper and plan on getting the RTX 3080, an 850W power supply might be a sound choice.

For the best bang for the buck, you can get the Corsair RM850. This PSU won’t break the bank while offering pretty solid performance.

The Thermaltake Toughpower G1 and the Silent Flower Leadex III 850 present two relatively affordable 850W power supplies that have excellent specs and performance.

We recommend models such as the Corsair RM850x, the EVGA Supernova 850GA, or the Seasonic Focus GM-850. Get the GX-850 for even better performance. Another interesting choice is the Fractal Design ION+ 860P, but this one is a bit more expensive than the competition while not providing better performance.

Flagship 80Plus Titanium PSUs we recommend include the following models: Corsair AX850, EVGA SuperNOVA 850 T2, and the Seasonic Prime TX-850.

Best power supplies For RTX 3090

The RTX 3090 is basically the Titan RTX replacement that comes with 24GB of GDDR6X memory and a base TDP of 350W. Some AIB models can go near or cross the 500W power limit meaning you have to get a pretty powerful PSU if you plan on getting a card such as the ASUS RTX 3090 Strix OC or the EVGA RTX 3090 Kingpin Hybrid or Water.

Minimum – 650W

The minimum PSU for the RTX 3090 should have about 650 watts of power. The card seeps 30 more watts at its base power limit than the RTX 3080 pushing the 600W PSUs out of the consideration, especially in case you run an overclocked 10900K or the 3950X. The full list of recommended PSUs can be found above, in the RTX 3070 section. Just ignore the 600W models as well as the budget picks.

If using SLI or tunning a workstation – 1000W or more

Prosumer users who plan on adding two RTX 3090 cards to their build have to get at least a 1000W power supply. Those who want to couple a Threadripper with two RTX 3090s should aim even higher.

The best SFX power supply series is Corsair’s famous SF PSU series. It contains PSUs up to 750W so, in most cases featured above, you will be fine. Another excellent SFX PSU series is the Focus SGX from Seasonic. This one includes only a 500W and 650W models so for the best performance pick the Corsair SF750. Also, when it comes to quality alternatives, there aren’t many. The best choice are probably the ION SFX models from Fractal Design. You also have the pretty good EVGA SuperNOVA GM series, that comes in the compact SFX form factor.

But, ultimately, the SF series from Corsair takes the throne. Firstly, it’s available in 750W flavor while the most powerful EVGA Supernova GM has only 650 watts of power. Secondly, the other two manufacturers make SFX-L power supplies, which are larger than SFX units and won’t fit every Mini-ITX case.
