FPS drops due to a weak power supply?

Evening. I have a question. Can a power supply with too few watts cause FPS drops? I have an RTX 4070, Ryzen 7 5800x, and 32 GB of RAM. Until yesterday, I thought I had a 650-watt power supply, but that's not the case. It's only a 400-watt power supply. So the wattage is actually too low.

That’s very good. If the components are underload and more need but nothing comes to throttle the power or the PC crashes. For the rtx 4070 and the process are 400w really too little

What?

the computer draws as much power as it needs either the power supply supplies the power or the voltage breaks as far as the computer switches off.

Other possibility (healthier) would be that power supply switches off because it is left off and it does not even come to the voltage drop.

You don’t get FPS Drops.

No FPS Drops do not get your computer will need a maximum of 330-360W.

The card needs 220 watts to take the CPU and the rest of it then you are very fast in critical area at only 400 watts but yes this does not give FPS Drops……a good power supply switches off, a bad flies around your ears

So 400Watt is really little or should just come to her border.

But you could subdue your CPU and Graka, so it could be enough.

Otherwise there should be a 550 watt power supply (at least pure).

But that’s why you don’t get FPS Drops, but you don’t know what to say or think, proves everyone can have a PC again, but have zero basic technical knowledge.

Sure, you didn’t.
And for that, you gave us this indirectly.

You don’t just think so, or you wouldn’t ask that.
Google alone would have searched you out matching forums etc., where you would have received a suitable answer.

But to come up with the idea that a low power supply/power that can come to FPS Drops, sry that has to do NULL.
Because neither the Graka beats down because of it or the like.

I’m sorry you testify that you have no idea of the technical matter of the computer area.

I don’t know if you bought the PC like this or if someone has assembled this power supply or the entire PC.

Fact is: The PC will start at some point when the power supply has reached peak values too long and too often and then simply can no longer be used because too much power is consumed than it can supply.
Because the peak values were definitely achieved here and there.

Remedies could be an emergency solution to subvolt the CPU and GPU.
With this, you can save up to 100-150watts to lose OHNE performance.

But you already know, you’d just have some idea.
JEDER, who has good basic knowledge of PC hardware, should/may know.

And if you had at least some basic technical knowledge of it, you wouldn’t ask this question/question.

FPS Drops due to a low power supply -.-

How can you not know what power supply you have in the system?
Even if you know how to build a PC, you’ve learned how to put together matching hardware.

You compare it with a chessboard.
You know how to build it, but how to play it, let alone strategies etc….

This has nothing to do with Fass, I just count the facts together.

Fact is, however, you would have heard etc. Then know how to subvolt etc. and what that brings.
