4070ti power supply?
I had already bought a new case 2 years ago and a 600W
“Be-quiet! Pure Power 11” power supply two years ago, and it was supposed to be for my current older computer. I haven't used the case yet, but I already had the power supply installed. It's sitting around in a plastic case like this ^^
Now I wanted to build a completely new system, just use the case and power supply.

probably an MSI DDR5 board
i7 13700kf
if the MSI, then G. Skill 32GB DDR5
GigaByte RTX 4070 Ti EAGLE OC 12G


Can I still manage with the power supply? I don't want to buy a new one because it hasn't even been used yet.

what psu exactly?
bequiet pp 11 has many variants from 300w to 1200w

nvidia recommends 700w psu for the 4070ti
higher wattage psu would put the psu in a more efficient range (less heat less wasted energy from the psu)

I did post that...600W^^

600W is not enough for that, would not run this setup with anything less then 850W.

You would want modern one that comes with 12+4 pin connector for RTX 4070 Ti instead of using Nvidia`s garbage adapter.

Yes, I thought so. Gigabyte specifies 750W.
I thought it was possible, because some people write that it also works with 650W.
I even wanted to buy a Super, but it doesn't make sense for 5 frames.

Unfortunately, a 4070 has 10-25 frames less than a ti, which is a lot.

It`s not just 4070 Ti, i7-13700K is also quite power hungry.

Yes, I forget that.
I've just thought of something. I actually only wanted to spend 1000 euros. Something like that.
I'll probably flirt with a 4070.
I'm looking through that right now.
It's rated at 650W and should run with the 600 for a while.
But then the idea is a DDR4 board. Since I've always used Gigabyte, it would be a:

Gigabyte B760 Gaming X DDR4 Intel B760 So. 1700 Dual Channel DDR4 ATX Retail + 32GB DDR4 Ram
GigaByte RTX 4070 GAMING OC V2 12G
and the I7 13700

That would be worth a try without buying a new power supply, wouldn't it?

With the amount of issues Intel currently has with their 13th and 14th gen CPUs you are probably better off with i7-12700KF. Performance difference is not much and it`s lot more stable.
Das Licht Jul 29, 2024 @ 4:30am 
That would have been my next question.
You've already answered it for me.
Then the good 600 would be enough, wouldn't it?
After all, 50W is not self-destruction.^^


I now have an i7 3770k
and a GTX 1660Super OC 6GB.

I bought the board/CPU 10 years ago and updated the graphics card once. But at some point it's over.
It runs very well in many games in terms of settings, but not everything. It just lacks the performance techniques.

Here's what I found with a little google FU

Weak power supplies leave the components of your devices without the necessary power to perform, causing malfunctions and failures across the board. Failures due to low power have a knock-on effect of causing system crashes, data losses, and, most importantly, damage to your devices

Now you want to risk that, it's your computer ; )
Das Licht Jul 29, 2024 @ 4:52am 
That is clear. But the specifications are always the absolute maximum.
I have done this from experience, because I have been assembling my computers since the 90s. And Gigabyte specifies 650W. Of course, that already includes a CPU, because a graphics card doesn't need 650W of power. And if it is a 12700, it will certainly consume less than the 13700. I would have to look for the specifications.
I don't want to deny that at all, but the reduced performance would be shown by an increased temperature rather than a crash. Because then a 650W power supply would almost always work at the maximum limit and that would be nonsense. Are we sure we agree?
I'm only asking here because I'm rarely up to date and a community always knows more than if I had to search for it first.
Just from the experience of many gamers.
It was also about the “ti”, but that's finished because at €770 it's still too expensive.

850W Minimum for any system running on a Gen. 5 platform, Gen. 6 may need 1000W or more.
600W was ok in like 2008-12.
Tralalero Tralala Jul 29, 2024 @ 5:05pm 
I think like a 750w psu should be fine imo. I run a 850w with a 5800x3d and a 4070 ti super but I only draw maybe 500w at most in any real world scenario (including cinebench and 3d mark). You could probably use a 600-650w build with my config.

I think since you have a i7 13700kf I think a 750w should be fine with a decent enough amount of headroom

Lmao I ran a 500w white psu with a gtx 970 and i5 4690k in 2014-2018 and then a 650w bronze psu with a rtx 2070 and a ryzen 3600x from like 2018ish to 2024.

The very most basic calculation you use to establish the bare minimum is C.P.U. T.D.P. + G.P.U. T.D.P. + 150. That's subtracting the 150 corsair allocates to efficiency and upgrade overhead.

So, based on the 4070 ti, the result is 219+285+150. The final result is 654, and consequently that 4 watts of extra bumps you up into the 750 watt class (since 700 watt supplies are rare), and realistically you probably should have that extra 150 watts of overhead, if not more to future proof the supply, so we're really looking at more like an 850 watt supply if you want to play it straight and by the book.

Mulling over the options I'd say get the Cooler Master GX III Gold 850W ATX3.0 Full Modular Power Supply[www.amazon.com]. It's an A.T.X. 3.0 power supply so it is required to adhere to certain excursion thresholds, and includes a 12vhpwr cable.

Yep,first of all, thanks for all the tips.
I have reconsidered everything and especially the reference to the 13700 and the current problems at Intel have brought me to the video with the AMD Ryzen 7 7800X3D and I see exactly what I want. Low power consumption and stable.

66000 sales on Mindfactory also say what it is.
It also has its quirks, which I've seen on YT, but that was a year ago, which has something to do with the chipset driver. The core assignments.
No problem.

Then it would be a Gigabyte 4070 12gb OC Windforce
Gigabyte Board and G.Skill Ram.
Whether DDR4 or DDR5, I still have to think about it.


Then I can at least test the 600W. If there are problems (even just once), then I'll just buy another 850W.
I think I got my answers and especially the problem with Intel, which I only realized now. I've only ever used Intel since the 90s (when I used AMD).
So why buy a 12700 when the AMD is a rocket.
CPUs should always be designed with the future in mind (my own experience)
and according to AMD, the socket will still be supported for a while.
I think I will only ever have to change the graphics card with this system.
Thank you.

@Tonepoet

I think the power supply I bought comes with everything.
I even installed it in a new, unused case, but have never used it. It's been sitting around the apartment wrapped in plastic for 2 years.
I think it has all the connections.
I still have to be careful with the cooler though. There is a cm limit in the instructions. I only know the boxed Intel fans.
Yeah, just 10 years ago, eh? lol
So there's still some research to be done ^^

As a tip, because many believe that a 4070 with 600W would not run.
Have a look at the comparison with a 4070.
I am currently doing this with a 4060ti (which is too slow, first of all)
the consumption is less than 200W!
What does the AMD processor consume?
120W? The cooling capacity of the CPU cooler is 150W. So what else is there to come?
Now do the math.

There are many videos. But they all do the same thing.
So here's one as an example. You probably know it yourselves.
But it's interesting to compare these two cards. I did the same with ti and super. In every direction.
And the first comment says it too. The entry into the 40s...is a 4070.
