The new Nvidia RTX 3070 is a high-performing card without being too expensive.
How Many Watts for RTX 3070?
- The Nvidia RTX 3070 has a TDP of 200W, so we recommend a power supply with at least 550W to use the card at its maximum performance.
Why is the power supply number that much higher?
Because every graphics card has an average and a peak power consumption. While most will stay in the lower, average part for the majority of their life, you want your power supply to be able to handle any peaks that happen during heavy gaming, even if just for a single second.
On top of that, the PSU doesn’t just provide energy to the RTX 3070, it’s responsible for your entire computer.
Is 500W Enough for RTX 3070?
No, a 500W power supply is not recommended for the RTX 3070. Even the minimum 550W recommendation assumes the rest of your components are not power hungry, which is rarely the case if you are building a gaming system.
Don’t save your money here because you’ll run into issues.
Is 650W Enough for RTX 3070?
Yes, the Nvidia RTX 3070 will work perfectly good with a 650W power supply.
However, the PSU powers all of your components, so this depends on your specific computer setup and if you have done any overclocking.
What Power Supply for the Nvidia RTX 3070?
I’ve been using Corsair PSU’s for a long time and there’s nothing better for the price. I recommend the Corsair RM650X which is a 650W, gold rated, fully modular power supply.
The biggest issues will be finding one that it’s in stock! If your budget allows you then get the 750W which is almost always available.
If you’re looking at some other brands, just make sure to stick with the most popular ones. Also, don’t go below 700W especially if you know you will upgrade to an even better card a couple of years from now. Price differences between power supplies are not that drastic.
Can the RTX 3070 Run Games at 4K?
You can run many games at 4K around 60fps or above, but you will have to change your game settings to medium/high for quite a few, and rarely ultra high.
Something like Forza 4, or games that don’t require too much work, will easily reach 100fps and higher, but a more complex (think Metro, Red Dead etc.) game will put a test on your 3070.
4K is still quite a difficult thing for most graphics cards, and this one is no exception. You’ll have to look at the 3080 as a minimum for constant high fps 4K gaming.
Can the RTX 3070 Run Games at 1440p at 144Hz?
This is where the Nvidia RTX 3070 shines the most.
As a matter of fact, the 3070 is hands down one of the best bang for the back GPU’s out there, and will be for quite a long time. If your goal is to game at 144Hz in 1440p, it will be ideal, and we don’t recommend going for anything more expensive (3080 or higher) if this is your ultimate goal. The ~10-20% difference is not worth a couple of hundred dollars more.
How Many Monitors Can Nvidia RTX 3070 Support?
The card can support up to 4 monitors.
There is 1 x HDMI 2.1 port and 3 DisplayPort 1.4a ports. However, make sure to check your card specifically before buying, as some companies might have 2 x HDMI and 2 x DisplayPort rather.
The maximum resolution it can display is 7680×4320, which means you can run 2 x 4K monitors, but it’s not nearly enough for a 3 x 1440p monitor setup. If you want to run 4 monitors at the same time, you will have to stick to 1080p as the card is not strong enough.
