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.
Best Price And Performance
Corsair RM650x
Staff pick
This 650W PSU's heat and efficiency are rated 80 Plus Gold, near the upper end for this type of hardware. The fan won't be heard unless the system is being taxed, thanks to a smart control that keeps RPMs low while idling. It's fully modular, meaning you can connect only what you need to connect for easy cable management. A 10-year warranty is included.
Tons Of Power
EVGA SuperNOVA P2 750
Editor's choice
If you're worried about your system not having enough power at 650W, you can always upgrade to the EVGA SuperNOVA P2 with 750W of power. This should set you up better for future upgrades and doesn't cost a whole lot more than lower-power PSUs. It has an 80 Plus Platinum efficiency certification and a 10-year warranty, plus it's fully modular for easy connections without clutter.
Budget Option
Cooler Master MasterWatt 650
Cooler Master makes some quality PSUs, and its MasterWatt 650W option comes at a great price. It has an 80 Plus Bronze efficiency rating and a five-year warranty, which aren't as impressive as the top picks, but it'll still get the job done. The 120mm fan runs quietly when not under load, and it's partially modular to help with cable management.
High-End Pick
Seasonic PRIME TX-650
Have a big budget for your next PC build? The Seasonic PRIME TX-650 has an 80 Plus Titanium efficiency rating and a 12-year warranty, putting it near the top of energy management and durability. 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.
Built-In RGB Lighting
Thermaltake TOUGHPOWER Grand 650
For those who think PC hardware isn't complete without RGB, there is the Thermaltake TOUGHPOWER Grand 650. It has five different RGB modes controlled by a dedicated button on the PSU's back, plus it's modular for easy cable management. The 80 Plus Gold efficiency certification ensures it doesn't waste a lot of energy and a 10-year warranty helps protect your purchase.
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. 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 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.
