PC stops working, it's not related to the temperature.
PC stops working, it's not related to the temperature.
The PC powers off unexpectedly, such as during gaming sessions. The temperature seems normal, it's not the hard drive, and I'm unsure what to do. Under stress tests for CPU or GPU, it doesn't shut down or overheat much, but after playing a game it does. It's frustrating. I have the latest drivers and no overclocking. If I leave the power cord plugged in when it shuts down, it won't let me interact with any buttons. It's not dirty.
The PSU's make, model, or part number is provided. Its age is also mentioned, along with whether it was purchased new or used/refurbished.
Assuming it's a prebuilt computer, I understand the model number beyond the Product ID code. Does that match what you're looking for?
The power supply I purchased a year ago is the Aureox 650W, model ARGXU-80PBZ-650W, and it's new.
Immediately suspect a PSU problem since you're unfamiliar with that branding. This might not be accurate. What is displayed in Event Viewer and/or Reliability History? It seems you're also using integrated graphics. The gaming appears to be 720/60 with low settings? My advice would be to execute Furmark and Cinebench 2024 over extended periods while monitoring temperatures. If the system shuts down, allow it to cool briefly, remove the side panel, and retry. This may help identify if temperature drops and stability improve.
Absolutely terrible quality power supply unit. It's not a 650W model; it features two 12V rails, each supporting up to 276W, giving a total of 552W. The official spec sheet confirms it's a 550W unit, not the 650W advertised. I haven't seen any credible reviews for this particular model before, which is normal.
Given your temperatures are acceptable, the main concern is the power supply itself. The solution would be to replace it with a higher-quality unit.
Recommended alternatives include Seasonic Focus/PRIME, Corsair RMx/RMi/HXi/AXi, or Super Flower Leadex models V/VI/VII/Gold/Platinum/Titanium.
All my PCs are powered by Seasonic, with full specifications and images attached in my profile.
If you don't have a dedicated GPU, the 550W PSU should suffice. Otherwise, a 750W unit would be ideal for an RTX 4070, while an RTX 4080 requires a 1000W unit and a RTX 4090 needs 1600W.
Thank you for your message, I'll check to see if this is the issue!
On the 22nd, did you make any adjustments? I notice you have Ryzen Master installed. Is it solely for monitoring, or are you attempting an overclock? Are there any changes to the BIOS settings? I agree with your worries about the PSU, as mentioned earlier.
