Best PSU for RTX 4070 Super

The RTX 40-series Super variants are the latest announced GPUs from NVIDIA, and of course, CORSAIR can provide a number of perfect power supplies for them. Specifically, this article will help you find the best PSU for the RTX 4070 Super, just like we did for the RTX 4090, 4080, and others. Those with a bit of additional cash might be looking for the best PSU for the RTX 4070Ti and 4080 SUPER.

It's t’s worth noting that all variants of this card, unlike some of the regular 4070s will use the 12VHPWR cable, or the triple cable adapter (Included with the founder's edition). So, we’ll make sure to only recommend PSUs that use this connection for simplicity’s sake.

• PCIE 4.0 X 16 SLOT (For best performance)
• 650W Power supply or greater.
• MIN 3 x 8 pin PCIE Connectors + Adapter provided / 300W or greater PCIE GEN 5 power cable.

As per usual, we prefer to recommend PSUs with a bit of spare wattage above the recommended amount. This way you’ve got more room to upgrade other components in the future. Additionally, many of our PSUs wont spin the fan at all if you’re only using a small percentage of the PSUs capabilities. If you can afford it, getting an over-specced PSU is the current meta.

Given that the RTX 4070 Super needs a PSU around 750W, we’re going with the CORSAIR RM850x SHIFT as our top choice.

It’s fully modular of course, which means you don’t have to deal with a bunch of extraneous cables, but it’s novel side-mounted connections mean that it’s never been easier to manage the cables you do actually need.

This in addition to it’s 80 PLUS Gold efficiency, latest Type 5 micro-fit connectors, and the 10-year warranty, makes the CORSAIR RM850x SHIFT the best PSU for the RTX 4070 Super.

A big ole’ gaming PC tower might look plenty glorious and garner unparalleled upvotes on Reddit, but not all of us have a 3-metre long desk capable of holding a 50kg PC.

This is where a small form factor case like the CORSAIR 2000D come in handy. These cases are designed to accommodate even the largest modern GPUs, however, you’ll need a SF-L or SFX PSU to make the most of the surprising amount of space in these cases.

So, if your RTX 4070 Super is going into a small case, the CORSAIR SF850L is the best PSU to use here. In addition to being way more compact than normal PSUs, it’s still fully modular with an 80 PLUS Gold efficiency rating and a zero-RPM mode. This means you get a smaller PSU without compromising performance.

Of course, some people are unconcerned with side-mounted cables or compact designs. They just want a power supply that shuts the heck up and does its job. For these people, the CORSAIR RM850e is the correct choice here.

Just like the other options on this page, it’s fully modular, and 80 PLUS Gold certified. But the RM850e is specifically designed to be as quiet as possible. Advantageous to all, but particularly vital for those who have their PC on the desk right next to them and those who don’t wear a gaming headset constantly.

We mentioned at the outset that over-speccing your power supply is our preferred way of buying a PSU. This is still true, however for many people, this might come across as unnecessary. This is especially true if you’re trying to optimize the budget of your PC build. Less money spent on the PSU, more budget for that 4070 Super right?

So, the best 750W PSU for the RTX 4070 Super from our range has to be the CORSAIR RM750x SHIFT. The exact same features as the 850W version we recommended at the beginning of this page, but more affordable.
