Best PSUs for RX 9070 XT and RX 9070 in 2025 – our top picks
Table of Contents
The RX 9070 XT and RX 9070 are set to go live on March 6th, and we’re only a couple of hours away. The reviews for these graphics cards are already live, and their performance looks seriously impressive, but there is also something that caught our eye.
While the power requirements for these GPUs are listed as 304W and 220W for the RX 9070 XT and RX 9070, some reviews show that the XT variant can consume upwards of 400W, meaning the 750W PSU recommendation might be a close call but should be enough.
That being said, if you’ve got a GPU like the RX 7900 XTX or the RX 6900 XT, you probably don't need to buy a new power supply as their power requirement matches that of the RX 9070 XT and should be more than enough for the RX 9070.
On the other hand, for a new gaming PC, you'll have to buy a PSU, and we've selected a couple of them that we think should be more than enough for an RX 9070 XT or RX 9070 power PC. The selected options are well above the recommended limit, but when it comes to PSUs, the more overhead you have, the better, as you can use it in future builds without running into power issues. We'll also update this article when we've tested these GPUs in-house and change the selections according to our findings.

Only one PSU got a 5/5 rating from us when we tested and reviewed it: the Corsair RM750x. This is an excellent power supply unit with great performance and efficiency, and the 750W capacity should be more than enough to handle the power requirements of the RX 9070 XT and the RX 9070.
This fully modular ATX PSU measures 150mm x 86mm x 160mm, and the cables aren't permanently attached to it. This makes cable management easier as you only have to make the connections you want and keep the rest of the cables in the box.
It also has an 80 + and Cybenetics Gold rating, which, according to Corsair, means that it is 87% and 90% efficient at 100% and 50% load. In contrast, the Cybenetics rating states that its efficiency should range between 87% to 89% efficient.
In general, the Corsair RM750x is an all-around strong choice of power supply. It brings a middle-of-the-pack feature and performance that make it a strong value choice.
PC Guide
So, there isn't a massive difference between the two standards, and to test this out for ourselves, we paired the Ryzen 9 7950X and the RTX 3090 together, which have a combined power draw of 520W.
We ran Furmark 2 to stress test the CPU and the GPU, and the power went from 127W at idle to 706W without any fluctuations, meaning the PSU was able to handle it without breaking a sweat.
So, whether you pair the RX 9070 XT or RX 9070 with the 9950X or the 285K, this PSU should be able to deliver the required power to each component and keep your system running seamlessly.
Also, the recommended GPUs to pair with this PSU in our review were the RX 7900 XTX and the RTX 4080 Super, which have 355W and 320W TDP, respectively, much higher than the unofficial 260W TDP of the 9070 XT. That being said, even if the official power draw for these cards turns out to be 300W, it still won't pose a problem for this power supply unit.
What users say
According to Amazon reviews, this PSU has excellent performance and efficiency. One reviewer said: “This 750W unit not only boasts an impressive 80 PLUS Gold certification for high efficiency but also operates quietly, thanks to its low-noise fan. The Zero RPM mode is a fantastic feature—my system runs silently during light loads, which is a major plus for a quiet workspace.”
- Wattage: 850W
- Form Factor: ATX
- Rating: 80+ Gold, Cybenetics Gold
- Design: Fully modular
- Great price for the features available in the PSU
- Fully modular and supports hybrid mode for silent running
- Strong efficiency rating in both 80+ and Cybenetics
- Original power connectors are rather bulky
- Short distance between the peripheral connectors on the same cable
If you're looking for a PSU that offers even more overhead than the RM750x, we recommend checking out the Seasonic Focus GX-850W PSU. This is a bare-bones PSU with no fancy RGB lighting, but it gets the job done, as we found out during our Focus GX-850W review.
This is also a fully modular ATX power supply unit, but its 850W capacity further opens the path to upgrades as you can pair even more powerful components together without running out of power overhead.
Seasonic also claims that it is 90% efficient at 50% load, and it measures 140 mm (L) x 150 mm (W) x 86 mm (H), so make sure to check your PC case can house it before purchase. A neat aspect of this PSU is that it has a three-phased thermal control.
What this does is that it keeps the PSU in fanless mode till 30% load and runs in silent mode till 50%. After that, the cooling mode is activated for the best cooling performance till 100% load. However, there is also the fan control button at the back.
A strong power supply that has improved over the years. Keeping up with the latest hardware while keeping the standard high.
PC Guide
When it is unpressed, the fan will only spin at high loads, but when it is pressed, the fan will spin regardless of the load, ensuring it keeps cool. This is a good feature for those located in a hot region, as the base temperature is high for every component.
Regarding its performance, at 115V, its efficiency was 88.845%, with a noise output of 30.73 dB(A). Switch the voltage to 230V, and the efficiency increased to 90.962%, and the noise output increased by 30.82 dB(A), which is a minute difference. Cybenetic did this testing, but it aligns with the Gold rating, meaning you should experience minimal loss during operation.
Overall, this is a good PSU with decent features and should be more than enough to handle the RX 9070 XT and the RX 9070, even if you've overclocked them to their limits.

If you’re looking for a PSU that will set you up for years to come and power through various upgrades of your gaming PC, we recommend the Corsair RM1000X Shift. As the name suggests, it is a 1000W PSU, which should be more than enough for the RX 9070 XT and the RX 9070. We’ve reviewed the RM1000X and gave it a 4.5/5 rating due to its excellent performance and efficiency.
You might be wondering as to why you’d need a 1000W PSU for the RX 9070 XT or the RX 9070, which have a 304W and 220W TDP, respectively. However, according to some online reviews, the RX 9070 XT can pull more than 400W, and during our in-house testing, we saw it peaking over 500W. The 500W spike was just that, a spike; it does show that it can draw power well above its TDP, and further overclocking could make this occurrence more frequent.
That being said, with this 1000W PSU, this isn’t a concern as it has plenty of safety features like Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP), all of which are designed to shut the PSU down if the set parameters aren’t met, safeguarding it and your PC.
Besides that, it is a PCIe 5.0 PSU, meaning it has a 16-pin connector and comes with two 2 x 8-pin connectors that are required for the RX 9070 XT and the RX 9070. So, this PSU has you covered in more ways than one. That being said, it has an 80 Plus and Cybenetics Gold rating.
An innovative yet simple change, the RM1000X Shift makes building, upgrading, and managing those pesky cables. With a great load of power and strong efficiency, it provides a great choice for your next build, as long as you’re willing to pay the premium for it.
PC Guide
The Cybenetics standard means that its efficiency should range between 87% and 89%, and it has an “A” rating for noise output, meaning its noise level ranges between 20 dB(A) and 25 dB(A). According to Noise Awareness, 30 decibels is equivalent to a soft whisper, and this PSU is even quieter than that. It also has a Zero RPM mode, which keeps the fan from spinning till sufficient load isn’t detected.
Regarding its performance, we’ll take the output of Cybenetics testing. With a 115V connection, the RM1000x has a 88.494% efficiency with a noise output of 23.62 dBA. On the other hand, the 230V connection saw an increased efficiecy as higher voltage results in lower current, which in turn, leads to better utilization of power and lower loss and resistance. It had an average efficiency of 90.176% and the noise level dropped ever so slightly by 23.59dBA.
Overall, the RM1000x Shift, is an excellent PSU and costs less than other 1000W PSU on the market. On top of that, its shift design also means the connections are on the outside, facing the side panel, rather than on the back. This makes it easy to form connecion and the fully modular nature is a definite plus.

- Minor rails have high OCP values
For the RX 9070 XT and RX 9070, an 850W PSU can be considered overkill; however, if you're short on space and are looking to build a low-profile gaming PC, we recommend checking out the Corsair SF850L.
According to TechPowerUp, the RX 9070 XT is a 2-slot GPU measuring 267 mm x 111 mm x 50 mm, and the SF850L measures 125 x 63.5 x 130mm, meaning they should easily fit inside a mid-tower case. The measurements of the RX 9070 XT haven't been confirmed yet, so take its measurements with a grain of salt.
This PSU features the ATX 3.0 and PCIe 5.0 connection, meaning it comes with a 12VHPWR cable that was made to handle power-hungry cards like the RTX 40-series lineup. So, it should be more than enough to handle the humble power requirements of the RX 9070 XT and RX 9070.
The Corsair SF850L doesn't drop much even as a small factor choice. Keeping costs similar to those of ATX supplies means you're not paying over the top for it.
PC Guide
It also has an 80+ Gold and Cybenetic Platinum rating. Taking the latter into account, it means that its efficiency should range from 89% to 91%. According to Cybenetics, it had a 90.577% and 92.33% efficiency at 115V and 230V, respectively.
However, it had a comparatively louder noise output, but that isn't surprising, seeing how the internal components have less space between them, so the fan has to spin more to keep them cool. It has a noise level of 36.09dB(A) and 35.92sB(A) for 115V and 230V connections.
Overall, this power supply unit is great for the RX 9070 XT and RX 9070 and can also be paired with more powerful GPUs. This is great because if you find a high-end GPU on sale, you can swap out your GPU and keep using the same PSU without encountering power issues.
What users say
According to Amazon reviews, the Corsair SF850L has excellent cable quality and performance. One reviewer said: “I normally don’t buy Corsair products, but I’m pretty impressed with this unit. I actually love that the connector at the PSU side are smaller than the ones that go inside your case. This removes any doubt which side is supposed to plug in where.”
- Wattage: 750W
- Form Factor: ATX
- Rating: 80 Plus Bronze, Cybenetics Silver
- Design: Non-modular
- Low cost in a competitive market range makes it an appealing choice
- Rifle bearing fan expected to outlast warranty which itself is OK for a low-rated PSU
- Compact size and limited cables make it easier to work with and not miss anything build
- Nonmodularity limits customization and available connectors, including one EPS and two individual PCIe (although one double causes less trouble)
- Can get noisy under loads, although less perceptible in a build
The RX 9070 XT and RX 9070 have decent power draws of 304W and 220W, respectively; however, real-world applications can require more power, pushing the graphics card’s TDP beyond its advertised limit. That being said, we’ve seen some RX 9070 XT reviews in which it was consuming 400W+, meaning if you were to pair it with a high-end CPU like the Ryzen 9 9950X3D or the Ryzen 7 9800X3D, which has a 170W and 120W TDP, respectively, the total power draw would be 570W or 520W.
What this means is that with a 750W PSU, you’d have 180W and 230W overhead, which should be more than enough for the rest of the components and even allow for slight overclocking. That being said, if you’re looking for a pocket-friendly 750W PSU, we recommend you check out the Corsair CX750.
At the time of writing, this PSU costs $79.99 and, in our CX750 review, got a 4/5 rating. This power supply unit has an ATX form factor but is non-modular, meaning you can’t remove the cables that aren’t being used and will have to adjust them in the PSU compartment of your casing, which can cramp up the space.
If you're after a more budget PSU, the Corsair CX750 provides a good choice, dropping down from its initial cost makes it a lot more competitive choice
PC Guide
Besides that, it has an 80 Plus Bronze and Cybenetics Silver rating. According to Corsair, the 80 Plus Bronze rating means it’ll be 85% and 82% efficient at 50% and 100% load, and the Cybernetics Silver rating also puts its efficiency between 82% and 85%. To test its performance, we paired it with the Ryzen 7 7950X and the RTX 3090, which have a 170W and 350W power rating, totaling 520W.
After everything was set up, we ran the Furmark 2 stress test, and the CPU and GPU power spiked at 369W and 196W, respectively, but it dropped down to 190W for the CPU. This means the CX750 was able to provide a stable 565W of power at max. Our power meter showed the PSU drawing 736W at full load, which is close to the limit, but despite that, the CX750 did a great job.
That being said, you can see that even the 7950X and 3090 consumed more power than what they were rated for when pushed to the limit, and depending on the workload, the same can be expected from the RX 9070 XT and the RX 9070. However, for normal workloads, the CX750 should be more than enough to get the job done without burning a hole in your pocket.
What users say
According to Amazon reviews, this power supply unit has excellent value for money, build quality, and noise level. One reviewer said: “At the moment, it has worked perfectly fine for me. I've yet to have any issues and it performs extremely well for its price range. Overall 9/10.”
How to pick the best PSU for the RX 9070 XT and RX 9070
Before you settle on any one power supply, there are a couple of factors that you need to consider. We've listed some of the factors below.
Power requirements
The first point of contact while looking for a PSU for your build is to consider the power requirements of the GPU and the CPU. In this case, the RX 9070 XT has a 260W TDP, which hasn't been officially confirmed, and if you pair it with a Ryzen 7 9800X3D, which has a 120W TDP, the total power draw would be 380W.
After that, you can add in the requirements for the other components, and even if we round it off to 450W, which is a stretch, you'll still have 300W of overhead, which is more than enough to overclock the GPU and the CPU.
Efficiency
The efficiency rating of a power supply unit determines how efficient it is in terms of how much of the power being pulled from the wall socket is being delivered to the PC and how much of it is lost in transit and as heat.
The higher the efficiency rating, the better performance a PSU will have, but it'll cost more. A good point to start is a Gold-rated PSU and anything above that comes in the enthusiast category. There are two standards that determine a PSUs efficiency rating.
- 80 Plus
- 80 Plus Bronze
- 80 Plus Silver
- 80 Plus Gold
- 80 Plus Platinum
- 80 Plus Titanium
- Cybernetics Bronze
- Cybernetics Silver
- Cybernetics Gold
- Cybernetics Platinum
- Cybernetics Titanium
- Cybernetics Diamond
Will a 750W PSU be enough for the RX 9070 XT?
The answer to this question depends on the CPU you pair it with and the workload. If you pair it with a budget CPU like the 9600X, which has a 105W TDP, a 750W PSU should be enough for this combination because even if the RX 9070 XT pulls 450W and the 9600X pulls 130W, it’ll consume around 580W, leaving you with a 170W overhead.
However, if you pair it with a high-end CPU like the 285K, which has a 250W TDP and, depending on the workload, can exceed that, the total power draw would be approximately 700W. This leaves very little for other components, and a 750W PSU might not be enough in the scenario, and it would be better to opt for an 850W PSU.
