So what PSU do you really need for the RTX 3070?

*edit*

Hi, I'm by no way an expert, but I have hands-on experience with building systems and selecting power supplies. My video shows power consumption figures and these are not necessarily the power draw numbers. They are not exclusively 1:1, but that said, they are not wide apart. My advice is generally to add 15-20% onto your system power draw to allow for system growth and to nullify system power spikes.

Tip: Find the TDP of your current card and if it's 220w or less then your PSU will be fine.

In the case of the 3070, people have reported that a 500w 80+ bronze unit has proven to work well with a 3600 & 3070 @ stock. Now this is fine if it's what you have, but I would suggest going for a 550w+ gold unit if you're buying new. All the better to go 650w+ if you can. I know that PSUs are expensive at the moment but so are your CPU and GPU.

Good luck with your building and hopefully you get a card at MSRP :)

Hi there,

Nvidia suggest that a 650w PSU is required, but may work with a lower wattage unit. What is the reality?
We test two systems 1) a Ryzen 5 3600 & 2) a Ryzen 9 3900X for power consumption.

If using a 500w 80+ bronze unit you may run into issues with spikes, but I think a 550w 80+ gold good quality unit and above should be fine.

Check out the below calculators if you're unsure.

Remember that PC parts are expensive so look after them with a good quality PSU and not a random no name brand.

I am running a 8700K at 4.8GHz and a RTX 3090 XLR8 at 1900MHz on a 750w Bronze rated OCZ PSU.

I am pulling 540-580w from the wall.

I would recommend:
- 3070 = 550 - 600w
- 3080 = 650 - 700w
- 3090 = 700 - 750w

You want that 100w headroom and it has to be a good Bronze rated PSU or better, preferably a gold rated one.

You can even get away with Platinum 600w PSU's for 3080's and 650w Platinum PSU's for 3090's.

I think they were rated based on the fact that people have bronze rated PSU's like my self, I was planning to get a 860w Seasonic for my 3090 but after testing... I don't need to.

Thank you for answering my question without putting it in a 20 min Video :)

we all need a guy who just says the important stuff like YOU, subbed mate.

[shinocg]

i have been asking youtube this question since the launch thanks for answering me today <3

Nvidia overspec their recommended psu because they dont know what cpu are you going to be using with it or if you are using a shitty psu.

[pjmk]

You're the best. Cheers for this!

[allenwalker]

Thank you for this video I wish other would make more videos like these where a lot of people really think about these kind of questions about the lower GPU other then the 3080-3090

[jasperolalia]

crazy how you have under 1k subs, quality on point!

[andreslfr]

Thanks for the clear and concise explanation my friend. Liked and subscribed!

i'm using 550w with 3070 and 3800x and it worked fine with me over a year

[jonathanbalkaran]

Thanks man you will save me a lot of sleepless nights for my itx build because I bought a 550w power supply because the 650w was out of stock. Regretted my purchase every day until I saw this video!!

[PanicNvm]

Great video thanks, almost just took the plunge on a 850, just for when I get the chance to grab the new GPUs but I guess I'll not bother!

[swaggerman]

im picking up a 3070 so this is nice to hear, thanks for the info

[ccdd]

Wow! So you are saying that I could even get a 3080 and still use my 650w? Great video!

[pez]

Great video, short, to the point. None of this Long intro faff. I have a 550w 80 plus bronze which I assume should be ok for the 3070? Running alongside the 3600 too, B450m.

[tiborkristovac]

The way you are looking at the camera made me feel like you know all my secrets and im judged! Anyway here is a like because the information was great and thank you so much.

Maybe it's too late. But nice video. When buying PSU I usually check some review on Jonru forum and I always use watt meter. I run Ryzen 5 3500 with RTX 3060 ti. And it only draws 250-300 Watt all the time. But 300 watt rarely happens in my case. I use my computer just for gaming and browsing. And I only use CM MWE V2 450W. Good budget PSU with newer technology with DC to DC. So, if you're looking for good PSU is not all depends on how much watt but also consider the technology from the PSU itself and always read review. It's really helpful.

You have no idea how relived I am after watching this video

[karel]

using a 620w for 3070 + 5600x, never had problems.

U earned a new sub strait to the point
