PC crashes in graphics-heavy games?

I bought a new pc a couple of months ago.

With the following components:

Sharkoon RGB lite 100

AMD Ryzen 5 3600

ASRock Fatl1y B450 Gaming k4

16Gb DDR4 3000Mhz Ram

AMD RX5700Xt 8Gb

Crucial BX500 480Gb SSD

1Tb HDD

LC-Power Cosmo Cool LC-CC-120-ARGB-Pro

FSP Hyper k 500W

2x beQuiet Pure Wings fans

Windows 10 Pro 64bit

I've only played 2 games so far, that would be WoW and Minecraft.

I have all the drivers up to date.

Now to my question. I recently installed Black Ops 4 and this is now the first graphics-heavy game where I play and it was often the case that my PC simply shows a black picture and hangs up and restarts.

Then I installed Modern Warfare and was exactly the same game.

It takes about half a TDM game to happen.

In the 3D benchmark test, which is free of charge, my PC even crashed after 10 seconds.

Could it be because I have a too small power supply with 500W as the manufacturer of the graphics card recommends 600W?

I have already written support from AMD, BO4 and MW and everyone said it could be due to the power supply.

Long text, short question.

What could it be? Really the power supply?

I also had this problem, please turn on the computer, and see how your graphics card is installed, and also in the mainboard, etc., something was installed incorrectly for me and that was the same problem, first check all pins everywhere, whether everything is seated correctly, etc.

Thanks for the quick answer, but do it tomorrow morning. Now want to sleep first.

The 5700xt has a complaint rate of 7%. So it could be that she has a problem

Basically check that all pins are seated correctly and that everything on the mainboard is correct.

Then it can either be due to the power supply or your graphics card has a defect, I had the same problem and it was because of me at the time that the graphics card got too little cooling.

Had new ones and never a problem again.

If nothing works and you find no problem, send in a graphics card and request a new one.

Hope you get the problem solved.

Or the RAM

In normal applications, you almost never reach your 16 GB.

The power supply does not manage to absorb the peak loads of the 5700 XT and therefore crashes. Buy a new power supply, spend a little more on it. The higher quality, the better. I would go to a 600W power supply, either Seasonic Focus or BeQuiet Straight Power
