PC Crashing help

[stixx]

Hello, I need some help with my PC crashing. When gaming, my PC crashes in game. Crashes as in turns itself off. There are no errors in the Windows logs to help me understand what's happening. I believe it is related to the PSU but I have no way of knowing for sure without trying a different PSU. Is there any way that I can determine if it is a PSU issue without having to buy a new PSU? I have an AX1200 and running a 7800X3D and 7900XTX in the system. The crashing only started with this build and worked fine with my previous setup - the PSU was carried over from the previous build.

Crashes as in turns itself off.

Quick guess would be over current protection kicking in on the psu and shutting off, make sure you use separate gpu power cables to the 7900xtx instead of using shared pig tail cables. You can also check temperatures, overheating can cause immediate shutdown. Windows event log under the system sub section should show you errors of what's happening at the time of shutdown.

all that is checked, troubleshooting isn't the issue, it's that I don't have enough information to figure out what is going on - GPU has 3 separate power cables (no pig tails etc), nothing in the event log to tell me what's going on other than 'Windows has recovered from an unexpected shutdown'. Temps are in check as the build is watercooled and I am limiting frame rates to help further with temps.

Basically, I am asking how can I test the PSU to know if that is the problem without having to buy another one? Getting from a friend is also not possible as no one has a 1000w psu in my friend circle.

Any of them have an 850W?
That will be suffice to test with.


What spare parts do you have on hand.. Another GPU maybe?

Have you tried removing the card and running off the iGPU to test stability?

How are you doing this? Did you make any changes to the cards performance?

In the Radeon Software there is a Feature Called AMD chill. Perhaps try that option if you haven't already tried it.

What game you playing when this happens

Is it a fresh install of windows on this new build?
Did you have another GPU in there before the XTX?

Did you run DDU?

The main way to test a PSU is to draw a heavy power load from it, and generally speaking, the best way to draw a heavy power load is to run a power-heavy workload from the GPU, since it is the most power-hungry component in the system. So crashing under gaming already suggests a crash under high PSU power draw.

You can try running a GPU benchmark like Superposition (you can use the Game mode instead of the Benchmark mode to run a consistent high power load for an indefinite period). To add CPU power load to the test you can run something like Prime95, but loading the CPU in this way can conversely decrease the load on the GPU by limiting its performance.

What I usually do for a full heat load is run Prime95 Large FFTs only on 1 core with no hyperthreading, and then start Superposition on Game mode on 1080p Extreme. I also use HWINFO for more detailed monitoring of power draw. If it's a PC with only one screen, I use RTSS to make an overlay of the HWINFO readouts of power draw, temps etc.
