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)
-Gigabyte Aorus Gen4 7000s 1t M2
-Msi Geforce RTX 350 Gaming x 8g
-Fractal Design Ion+ 760P, 80 PLUS Platinum, 760 W
-Fractal design Define 7 Compact
-Arctic Freezer i35
 
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.
 
Sometimes when i'm working external hard drives might shut down for blink of an eye and start immediately again.
Two things.

1). Are the external hard drives 2.5" (laptop size) hard disks in a USB3 caddy or 3.5" (desktop size) hard disks in larger enclosures with their own separate 12V DC mains brick? Maybe their external SSDs?

2). Have you disabled Windows Power Management in Device Manager for all USB Hubs, etc? Also USB Selective Suspend in Power Management? See below.

Power

If the external hard drives are 2.5" and derive all their power from the +5V supply on the USB cable, they should be able to pull up to 900mA from a "standard" USB 3.0 type A socket, or up to 500mA from a "standard" USB 2.0 type A socket.

2.5" hard disks can usually run from 500mA on a USB 2 port, but they might be "happier" with up to 900mA on a USB 3 port. If the USB cable supplied with the 2.5" drive is USB 3 (blue tip), it's best not to plug it into a low power USB 2 port.

If the external hard drives are 3.5", they get their power from the +12V DC power brick. The USB cable is for data.

Hub Power Management

In their infinite wisdom (and to save the planet) Microsoft try to save a few Watts of power by switching off your USB ports when data is not being transferred. They also do this on WiFi and Ethernet chipsets. Bravo! No Global Warming.

The result is your USB drive may go to sleep periodically when power management kicks in. When you attempt to read or wite data on the disk, Windows powers up the USB port, but some USB devices don't like being put to sleep and may not wake up properly. Drive letters might not be reassigned, printers and scanners may not work after being disconnected. It's a real pain.

Open Control Panel, find Device Manager, look for Universal Serial Bus Controllers and open it. Work your way slowly down each entry. Look for the Power Management tab and open it. Clear the box next to "Allow the computer to turn off this device to save power" and click Apply. Move on down the list of USB devices and repeat.

You might also like to open Windows Power Options, Change Plan Settings (for active plan), Change Advanced Power Settings, Hard Disk, Turn off hard disk after, Setting and enter 0 (zero) to keep hard disks permanently on. Save settings. The default is to turn off hard disks after 20 minutes of inactivity.

Check further down for USB settings, USB Selective Suspend Setting, Setting and change it to Disabled. The default is Enabled. I don'r want my USB ports to be "suspended".

Microsoft's power saving aims are laudable in an office environment where hundreds of employees leave their PCs running overnight and at weekends, but on a home PC where you want continuity, shutting down and waking up devices is a pain, especially after you've nipped off for a coffee.

One final piece of advice. If you experience problems connecting fast USB 3 card readers to a front panel port, try connecting the card reader to a rear panel USB port. The cable run will be shorter. I use Startech 30cm/1ft USB3 cables on my Kingston CF and SD card reader to avoid long cables and data corruption. With modern card speeds exceeding 200MB/s (much faster with CF-Express and esoteric SD) it pays to keep cables short.
