Following its launch at CES 2024, PC builders were excited to get an RTX 4070 Ti Super into their rig – especially as its replaced any reason to go out searching for an original 4070 Ti. Of course, we’ve gone into the full ins and outs in our RTX 4070 Ti Super review, but overall, combined with 16GB GDDR6X vs 12GB and a bandwidth of 672 GB/s and 256-bit bus (compared to 504.2 GB/s and 192-bit in the original card), you can see clear improvements that mark the latest Super models more of a fit for 4K gaming.

Power supplies are often overlooked when considering how your computer system is built effectively. However, if your PC uses a powerful GPU, such as Nvidia’s RTX 4070 Ti Super, then choosing the right power supply can be an important step in ensuring your system runs smoothly. In this article, we’ve cherry-picked a list of the best PSUs for RTX 4070 Ti Super.

Products at a glance

How we picked

On the whole, we’ve taken a specific focus on PSUs that provide stable and efficient power delivery, particularly under typical gaming and workload scenarios. This involves evaluating PSUs for their ability to maintain consistent voltages and handle peak loads without faltering. The goal is to recommend units that not only meet the power requirements of the RTX 4070 Ti Super but also offer reliability and longevity: leaving room for upgradeability is a smart move. Of course, as we mentioned earlier we’ve already done our review of the 4070 Ti Super, so we’re familiar of how it performs under load, and are comfortable recommending this list of CPUs we think will be a good match-up based on our hands-on experience.

Recommended specs don’t go out the window either. We’ve noted how the 4070 Ti Super uses the same 285 watts of power as the RTX 4070 Ti, and connects to your power supply with the same (problematic) 16-pin 12VHPWR cable. Nvidia advises a 700 total system watts as a minimum for both cards. Needless to say, all our picks today go above and beyond this.

Noise level is another consideration, especially for users who prefer a quiet working or gaming environment. By integrating technical performance with user experience, our recommendations aim to provide users with PSUs that not only meet the power needs of the RTX 4070 Ti Super but also fit seamlessly into their overall system build.

What are the 4070 Ti Super PSU requirements?

As we mentioned just above there, Nvidia recommends a 700W minimum PSU for both the RTX 4070 Ti Super and the original 4070 Ti, so going for a unit of 700W or 750W at least should get you covered on the power supply front. In terms of dipping above or below this figure, it could be said that if you have a CPU that uses under 100W under full load, you might be fine with a 600W unit – these recommendations might be assuming that you’ve got something like a 14900K in your rig that’s already pulling 300W. However, we advise that you aim for above minimum requirements, as when you eventually upgrade to a bigger and better card, you’ll already have the necessary power already available to you.

Best in ClassExcellent
  • Wattage: 1000W
  • Form Factor : ATX
  • Rating: 80 Plus Gold, Cybenetics Gold
  • Design: Fully modular, side connectors
Reasons to Buy
  • High wattage PSU that’s both efficient and noiseless
  • Perfect for future-proofing your build, and should be a long-lasting unit
  • Connectors are now on the side of the side panel, making cable management easy
Reasons to Avoid
  • Aesthetics aren’t to everyone’s tastes
  • You don’t necessarily need 1000W of power for a 4070 Ti Super
  • Fairly expensive pricing

First up, it didn’t take us long to deduce that we think the Corsair RM1000X stands as the best PSU for builds using a 4070 Ti Super. For those with a little extra budget to spare, it won’t go amiss when investing in a solid power supply from one of the market’s best – Corsair. With a great load of power under its belt, and a heap of efficiency too, this PSU is certainly one to consider for upgrading your build. Personally, we liked it so much that in our RM1000X review, we awarded it with a lovely 4.5 stars.

As a 1000W PSU from Corsair, you can expect this PSU to have all the bells and whistles for a high-end system, and for users that like monitoring their power usage. There’s not much that the RM1000X can’t handle, and while it might seem a bit overkill for a 4070 Ti, 1000W is more than enough to future-proof you for years to come. What’s more, the RM1000X Shift is both rated by 80 Plus and Cybernetics to a Gold standard, whilst the latter also gives it an A sound rating. Powerful, efficient, and quiet: what some might call a triple threat.

Overall the RM1000X Shift is an excellent choice of power supply for your current or any future builds.

Another reason why this particular unit design is good is the movement of the power connector to the side of the side panel, making cable management just as easy as you’d want it to be. And of course, as a 1000W PSU there is plenty of power behind it but also a lot of cables included. There are seven PCIe connectors for all your GPU or add-in card needs, and it also includes the 16-pin connector as a native PCIe 5 PSU.

What users say

Cutting to the chase, the Corsair RM1000X is highly rated on Amazon, getting an average of 4.7 stars from buyers. Unsurprisingly, people seem to like the performance and noise levels of this PSU, with one reviewer commenting that the “zero RPM fan mode ensures silent operation during low to medium loads”. However, one of the few things that get a mixed reception is the aesthetics, with one user mentioning how “it’s not super elegant”.

However, one aspect to be aware of is the PSU’s inrush current of 51 Amps. While a high inrush current can be a concern in terms of potential impact on electrical circuits, particularly during power-on, it’s important to note that this is a common trait among high-capacity PSUs. In most home and office environments, this shouldn’t pose a significant issue, especially if the electrical setup is modern and well-maintained.

What users say

One user on Amazon wrote that the be quiet! Dark Power 13 1000W is a “really stable, solid and reliable power supply with lots of wattage to spare”, and this speaks of its overall good reception from users. It’s also a really sleek PSU: “aesthetically this power supply really is beautiful”. One thing worth mentioning though, is that a few users have mentioned that the connector cables that this unit comes with are a bit inflexible, so you may slightly struggle when it comes to curving them.

PC Guide

One limitation, however, is that the Smart BX1 is not a modular PSU. This means that all the cables are permanently attached, which can lead to potential cable management challenges in some builds. To mitigate this, planning the layout and utilizing cable ties or other management solutions can help maintain a tidy setup, ensuring optimal airflow and aesthetics in your system.

What users say

As far as budget PSUs go, this one seems to have gone down pretty well on Amazon, with 79% of users giving the Thermaltake Smart BX1 750W 5 stars. Obviously, at $70 it represents really good value for money, and while one user commented that it’s a “solid investment for gamers and PC enthusiasts seeking a reliable and efficient power supply”, one other mentioned that it “worked like a charm for my budget gaming build”.

Features and considerations

When selecting a PSU for the RTX 4070 Ti Super, understanding the GPU’s power demands is crucial. With a TDP of 285W, the 4070 Ti Super requires a robust and reliable PSU to ensure efficient operation. Nvidia’s suggestion of a 600W PSU provides a baseline, but it’s wise to aim higher to accommodate additional system components and potential future upgrades.

Beyond wattage, the efficiency rating of the PSU is a key factor. Opting for a unit with an 80 PLUS Gold or higher rating ensures better energy efficiency, leading to less heat generation and potentially lower electricity costs.

How many watts is a 4070 Ti Super?

The NVIDIA RTX 4070 Ti Super has a Thermal Design Power (TDP) of 285 watts. This figure represents the average power consumption under typical loads. When choosing a PSU for a system with a 4070 Ti Super, it’s important to consider the power requirements of the entire system, including the GPU, CPU, and other components, to determine the appropriate wattage for the PSU.
