Question Kernel Power Event 41 restores?
Hi
A few weeks back I experienced frequent shutdowns of my PC, recorded in Event Viewer as "Kernel Power Event 41" incidents. These events happened during unusually hot weather—temperatures consistently above 30 degrees for several days. Believing the heat might be the cause, I purchased an AIO cooler for my CPU. After installation, the shutdowns stopped completely. Yet today it’s happening again, and the weather is once more scorching.
I’m convinced the cooler is performing better than my previous air cooling solution, which led me to suspect other temperature-related factors in my system. A quick search on "kernel power event 41" revealed many possible reasons, including a failing PSU. Could it be that a PSU works fine at around 25°C but fails at higher temperatures?
During today’s crash, the computer wasn’t under heavy load; my wife was browsing the internet. However, I play demanding games and they didn’t trigger a shutdown, suggesting the issue might not be the CPU or GPU. Could there be another component involved?
Anyone here have faced similar problems? How did you identify the cause and resolve it?
My CPU is a Ryzen 5800x, motherboard an Asus 570x TUF wifi, and GPU a Powercolor RX7800 XT. Thanks!
My CPU model is Ryzen 5800x, motherboard is Asus 570x TUF wifi, and GPU is Powercolor RX7800 XT. When sharing a troubleshooting thread, it's important to provide complete system details. Please list your build specifications as follows:

Include the age of the PSU along with its make and model. Also, mention the current BIOS version for your motherboard. You mentioned switching from an air cooler to a watercooling AIO—please specify what you were using before the change. Additionally, could you clarify the ambient room temperature in your country?
Hi
I mentioned I’m located in England.
The temperature in my room was about 35°C due to the lack of air conditioning, and the space is compact with the computer adding much heat.
CPU: Ryzen 7 5800X
CPU cooler: Corsair H100 AIO
Motherboard: Asus x570 TUF Wifi
Ram: 32Gb Corsair 3200C16
Storage: WD_Black SN850X HS 1000Gb
GPU: Powercolor AMD RX7800 XT
Power supply: Gigabyte UD850GM (bought in October 2023)
Case: Corsair 4000X
Operating system: Windows 11

The cooler I had before was a Coolermaster MA410M.
A Google search for "kernel power event 41" reveals several possible reasons. One possibility is a defective PSU. Is it feasible for a PSU to function properly at an ambient temperature of around 25°C, yet fail at temperatures above 30°C?
Yes. Certain conditions or thresholds may allow X to work but not X+1.
Examine and compare what runs in the background when you use the computer versus when your wife does. Tools like Task Manager, Resource Monitor, and Process Explorer can help.
Identify any additional factors that might differ.

Extreme heat often impacts power systems.
It could be due to electrical issues or problems with your own high-power devices and/or home electrical setup.
Both intense heat and severe cold are known to trigger electrical issues.

Please ensure all crucial data is saved at least twice in separate locations away from the PC.
Check that these backups are recoverable and readable.

In Event Viewer and Reliability History/Monitor, search for other error codes, warnings, or informational events that might be recorded just before or during the Kernel Power 41 incidents.
I confirmed the country I'm in is England.
To reduce the heat in your room, consider opening doors and windows for better cross-ventilation, which can help disperse the hot air naturally. If this lowers your room temperature, try removing the front fascia panels to see if cooler air improves performance.
You mentioned a possible thermal problem with your platform. If the system hasn't been cleaned of dust and debris, it might be affecting its efficiency, as well as the PSU's ventilation. Is the system placed on a carpeted floor?
The kernel power error isn't the main issue. This happens when the system restarts without shutting down first. Any BSOD typically results in the logging of a kernel power error. Make sure to monitor the CPU and GPU temperatures. Disable automatic reboot on system failure. If you encounter a BSOD, take a photo and share it here (upload to imgur.com and post the link). If the restart is due to a power supply unit failure, then a BSOD should not occur.
The entire system is sensitive to temperature because all its critical parts—CPU, GPU, RAM, motherboard, SSD, HDD, power supply—are delicate electronics. Even the case fans have a specific ambient temperature range for optimal performance. The only exception is the PC case itself, which is made of plastic and metal. However, if the temperature exceeds 250°C, the plastic will melt and the metal components may deform or even melt.
This is one scenario, considering your PSU has average to good quality. It’s not ideal but still acceptable, placing it around Tier B+.
PSU recommendations:

Personally, I’d prefer a higher-quality PSU for a gaming setup. Tier A is ideal, such as Seasonic Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, or Super Flower Leadex Gold/Platinum/Titanium. Tier A- is acceptable, while Tier A+ is the best choice. (Refer to the PSU tier list I linked.)
My three PCs are all powered by Tier A PSUs: Seasonic PRIME 650 Titanium (Tier A+), Seasonic PRIME Ultra 650 Titanium (Tier A+), and Seasonic Focus PX-550 (Tier A). Detailed specs and images are available in my profile.

If you enable Sensors mode, you’ll see all the telemetry data the PC generates about its components. This helps monitor temperatures and detect any readings exceeding 80°C.
Even if the PSU is faulty, I still suspect the CPU is overheating. You experienced problems before, but switching to an AIO cooler resolved them. Now, with the heat, they’ve returned.
I also recommend setting all radiative fans to 100%. It may be loud, but maintaining PC operation is more important than occasional reboots or shutdowns.
During summer, especially in very hot areas, I’ve increased fan speeds in my builds to ensure better cooling.
This situation doesn't trigger a BSOD, so it might suggest the power supply unit is the issue.
