Best PSU for RTX 3070

Despite the 40-series and subsequent Super refresh clearly outperforming this card, the RTX 3070 can still perform very well, even with the latest releases.

Of course, the main benefit of buying a graphics card that’s no longer the new hotness is that you can buy it and afford rent the same month. Unreal financial techniques.

So, given that the RTX 3070’s price point is only going to get more and more accessible, we thought we’d go over some of the best PSUs to go with it. Let’s take a look at some options from the considerably broad range of options from CORSAIR.

RTX 3070 SYSTEM REQUIREMENTS

• PCIe 4.0 x16 Slot (For best performance)
• 650W power supply or greater
• 1x PCIe 8-pin
  (adapter to 1x 12-pin included)

As with the 3080, 4080, and pretty much any of NVIDIA’s GPUs, the power draw of the cards varies depending on which brand is making it. So, here’s a list of some of the most common RTX 3070 cards and their officially recommended minimum wattages.

Please note that this list is not exhaustive, so if you don’t see your specific model of 3070 in there, check the manual or the manufacturer’s website to make sure you’re configuring your system correctly. We’re actually going to go with PSUs that are slightly over-powered for the RTX 3070, as the additional headroom means that you’ll be able to upgrade your system a few times without necessarily having to upgrade the PSU. Additionally, it means that the PSU won’t have to work as hard to power the system, which is nicer for thermals. We will include a 650W option at the bottom of the page for those who are less concerned about upgradability.

If we’re talking modular PSUs, then the RM750x SHIFT is the correct answer here. Fully modular cables mean that you only have to manage what you need, and the way that they’re side-mounted makes cable runs even more direct. The RM750x SHIFT is also 80 PLUS gold and Cybenetics gold-rated for efficiency, and scores an A from Cybenetics in their noise levels testing too.

Those who really want to get deep with PSUs will want to have a gander at the power table and the cable configuration. We’ll include these specs for the other PSUs we recommend too.

With small form factor PCs continuing to grow in popularity, it’s worth taking a look at a fully modular SFX PSU for the RTX 3070, too. The CORSAIR SF850L is the best choice for those after a compact PC. It’s fully modular and is far more compact so you won’t have to worry about squeezing it into small cases.

But what if you don’t care about size, or side-mounted connectors? What if you just want a PSU that just gets the job done, allowing you to concentrate on the important things in life. Like Counter-Strike 2 and YouTube videos.

If that’s the case, then the CORSAIR RM750e is the top choice here. It’s modular of course, but the main feature is how whisper quiet it is. If you’re the type who like to entirely forget there’s a PC in the room, this is how you do that.

If you only upgrade your PC sparingly, or you like living life closer to the edge, then a 650W PSU will still be ok. We’d be remiss if we didn’t include one, so we’re going with the CORSAIR RM650. It’s fully modular still, despite its sub $100 price point and it’s a touch more compact than most ATX PSUs.
