Question Can a PSU with dust turn off the pc?

[Metinku]

Hello so my pc keeps turning off randomly every hour or so, But when i blow air into it keeps on for a whole day I also get the error Power Kernel 41 when it turns off.
So my question is does my pc turn off because of the dust inside the psu?
Thanks.

brand and model of the psu
how old it is?
could be overheating

No, dust is non-conductive. It does act as a thermal insulator though, but you'd have to have a lot of dust caked on it for that to b ea problem.

The power supply could just be broken in some way.

It could, most likely from suffocating it, Or preventing the fan from spinning. Though do note that idle a lot of PSU's fans do shut off.

But it would be nice to know the brand and model of the PSU plus the rest of your system components.

Its a unkown national brand but it's 600watt 80+ bronze It's around 3 years old, I don't think its because of overheating because even after hours of staying on it's still cool to touch.

I've stated the psu in the upper reply but the rest of my system components are as following :
Motherboard : Gigabyte B450M-H
Ram : 2x8gb DDR4 3000MHZ
Cpu : AMD Ryzen 5 1600
Gpu : Asus TUF GTX 1650
Ssd : Kingston 1TB Nvme2 SSD
I've done stress tests on all of them and all of them seems to be working finely

Also I should of asked this before hand, But does the system actually shut off or does it restart? If its restarting randomly that could be really anything, but it shutsdown on its own and you have to power it back up, that I would point at that no name PSU. 80+ doesn't mean its a good PSU thats simply a rating for how efficient it is or supose to be. Power Kernel 41 is just an error Windows throws out if its not shutdown properly like form a loss of power or holding the power button down until it shuts off.

If its unknown brand, I would have to point at the PSU just not quite being up to the task, most likely it doesn't even output 600watts on the 2v rail and it combines both the 3v and 5v rails to get a total, most good name brands only add up the 12v rails for the total output watts.

Also a PSU can be sporadic sometimes, or some kind of loads will make it fail while other heavy loads might not, I've seen this happen more times than I can count, there really is no proper way for the user to bench test a PSU unfortunately. The only thing you can do is find another PSU and do the same things that made it crash or shutdown.

Good Luck!

If the dust is causing it to overheat, yes!

Here's some info from MS on your particular error.

Also, you should invest in a little utility called 'Who Crashed'. It reads your crash logs, and translates them into plain english to help you troubleshoot problems like yours.

Get it here.

It turns off and I can't turn it back on unless I replug the psu from behind, Also like I said earlier could dust be the problem? when I blow air into it, it stays on for a longer period of time.
Also it isn't overheating and the psu fan is spinning.

Yup thats definitely the PSU, See a PSU had a bunch of different components, any one little part could be overheating inside it, or just gone bad, There isn't much you can do to save it, small amounts of dust should not hurt the PSU at all.

Blowing air through the PSU should dislodge enough muck to keep it going for another six months at the very least. How often do you change the air filter in a car? Certainly not on a daily basis. Get a new (high quality) PSU.

Alright thank you I guess i'll just replace the psu thank you again for your time.
