[SOLVED] My pc doesn't always boot unless I reset my motherboard

[encise]

Hello, so here are my specs

i9-10900kf cooled with z63
rtx 3080
32gb corsair rams
2 ssd's - 1 hdd
colorful z490 vulcan x20
gamemax 1050w

So my problem is my pc doesn't boot from the first time normally, I have to switch the powersupply to OFF then Click on the reset button on my motherboard for 15 seconds, then my pc will boot
And when it boot its boots with no problems at all, but when I turn the pc OFF and comeback after few hours to play again it doesn't boot at all, the pc turns on lights up and everything, but the screen is black, it doesn't boot at all, I can't even open BIOS
I have to do all the process all over again, Turn the PSU off from the switch on it, then click reset button for 15 seconds, then turn the PSU back on, now it works!! I hope someone can know what's causing the problem because I'm tired of this process and I think it can harm the PC If I did it everytime not sure about that

TLDR;
My pc doesn't boot, I have to turn off PSU reset my mobo to make it boot, Why is that? what's causing that problem

What do the capacitors on that psu look like.If they are small it means they are good,if they are big and chonky that means they are bad.
Try plugging your power cord to a different outlet.
Or in other words plugg the psu cable into a single outlet and see if it happens.

Here is my exact PSU model: https://gamemaxpc.com/productkkk/941-en.html
Here is how the capacitors looks like according to them

I'm not sure if that's considered big, but they are claiming its high quality, and about trying to change the power cord to a different outlet I will try that
But I don't think it will fix the problem because I used to power my old pc with the same outlet and had no problems, I will try it anyways and update here

When i asked how are the capacitos i meant how are they currently,not in the new psu.
Basically just take a look from your psu ventilation hole and see if any capacitor is bad.
Example of a good and a bad capacitor:
