If you're upgrading your PC for NVIDIA's next-gen 30-series graphics cards (GPU), adding one of these picks for the best PSU for RTX 3070 ensures you won't have any problems with the powerful new hardware. This is especially true if you're currently using an underpowered or aging PSU; not having enough power will usually lead to overall system instability and game crashes. NVIDIA recommends at least a 650W power supply unit (PSU), which is where we will focus in this roundup.

It's fully modular, and there's a dedicated fan control button on the PSU to switch between modes. It's quiet, it's efficient, and it has the 650W to power the RTX 3070.

Best PSU for NVIDIA RTX 3070 GPU

NVIDIA recommends a 650W PSU for the RTX 3070, but if you're currently working with, say, a 600W PSU, you might get along just fine depending on other hardware in your system. You can always give it a shot before picking up a new PSU. On the other hand, upgrading to something new — especially if your PSU is beginning to show its age — is never a bad idea. An old PSU can cause issues, no matter its wattage.

If you are ready to upgrade, our best PSU for RTX 3070 pick is the Corsair RM650x (opens in new tab). It sits somewhere between the high-end and budget options in terms of price, and it has the 650W recommended to power the RTX 3070. The 140mm fan's blades are curved to reduce noise, and the fan turns off entirely at low power usage. It's also 80 Plus Gold certified for power efficiency, reducing heat, and overall draw. It comes with a set of fully modular cables so that you only use what you need (keeping your PC case uncluttered), and a 10-year warranty gives you some peace of mind.

If you think you'd like to upgrade to something that might just better stand up to future upgrades, the EVGA SuperNOVA P2 (opens in new tab) with 750W of power is no doubt appealing. It has an 80 Plus Platinum efficiency certification for excellent heat and power management, it comes with a 10-year warranty, and it's fully modular for easy cable management.

These options not quite what you're looking for? Our general collection of the best power supply units for gaming might have what you're looking for. And don't forget to check our roundup of the best graphics card options out there as we await the release of NVIDIA's 30-series GPUs.
