Question Too low power supply maybe?

[Miikka170]

Hello,

I had pc with:
-Intel Core i9-12900K
-MSI RTX 3050
-Fractal Design Ion+ 760P, 80 PLUS Platinum, 760 W

Even myself see now that this might be a dum question, cause if GPU need 550w and CPU 241w, but can some one confirm this to me and tell me to go buy 1000w PSU?

Everything had worked fine for couple years, except some problems with usb-ports. I use computer for music producing and video editing. Sometimes when i'm working external hard drives might shut down for blink of an eye and start immediately again.
This wont happen with other computers when using these drives. And problem had shown with usb-ports on motherboard and with ports on case.
This maybe cause of too low power supply?

Earlier i have checked connections on motherboard etc. Now i started to find solution again for this and read about power supplies.
I don't know much about these things yet. It was my first computer i build and appreciate all help i been get from you people.

RTX 3050 don't need 550w on it's own. RTX 3050 8GB consumes 150w max and the RTX 3050 6GB 80w. Recommanded wattage for the whole system is 550w. The 760w of the Fractal PSU you have is plenty.

Thank you very much for this information!

So problem and solution must be somewhere else. Any ideas what might cause that error on usb-ports?

Really like to fix that, because everytime it happen i have to close and open premiere pro and project again to get those videoclips reloaded that have been lost on that shut down.

Here are other components listed:

-Gigabyte Z690 Gaming
-Intel i9-12900K
-Kingston Fury Beast DDR5 5600Mhz CL 40 32gt(2x16gt)

-Msi Geforce RTX 350 Gaming x 8g
-Fractal Design Ion+ 760P, 80 PLUS Platinum, 760 W

USB hard drives can consume enough power over USB to be significant, but that usually isn't the problem. If the drive is externally powered, or if the drive is on an externally powered HUB, then it won't draw power from the host PC at all. What does happen is for the signal quality to be insufficient at that speed. Otherwise 100% functional USB devices will appear to fail if the signal quality drops. I can't tell you how to test that under Windows, but if you are running Linux, it is somewhat easy to see the logs and query the USB. Do you have Linux available? Do you have a better description of why you think it is a matter of power? Note that a disconnect is not necessarily a power disconnect.

Your psu has worked fine for years.
If you now have problems, it might be the psu.
Test with a known good quality psu.
If all is well, initiate a RMA; your processor has a 10 year warranty.
The graphics card is the main variable for psu wattage.
No harm comes with using a much stronger replacement if you might ever want to use a top end graphics card.
