Your PC shut down two processing units.
Hello everyone, I encountered a serious issue with my recent build and already experienced problems with two 9600x units within three days each. After investigation, I suspect there’s a problem in the build process, so I purchased a power supply tester. I noticed that the 12V on the EPS and 24-pin connector drops to 11V for half a second before returning to 12V—this could be even lower than expected. Could this drop be the cause? Thanks to anyone who reads this.
ATX specifications require the +12V rail to remain between +11.40 V and +12.60 V. Nonetheless, I question whether your power supply unit or the +12V output is the root cause of your issue. Given you used an ASRock motherboard previously, that seems like a likely culprit. Very low voltage usually doesn’t damage components.
It’s not ideal, but 11V is close enough to the 12V rail to avoid immediate damage, and overvoltage usually causes failure rather than undervoltage. I’d recommend swapping out the power supply regardless. Probably the motherboard is the issue—unless you tried something risky like XOC, it’s likely a hardware problem. I’d definitely return it and get a different one if needed.
Disable automatic overclocking, as it seems to be the issue. I’d still consider purchasing a fresh PSU since AMD won’t upgrade those chips and the next one will cost significantly more than a new power supply. Possibly I’ll begin anew with a new motherboard instead of exposing myself to another CPU on a risky platform.
What is the motherboard? It seems many haven't inquired so far. Some systems have faced problems damaging CPUs, especially with the newest ASUS 800 series and 9800X3D chips.
Check if COU and cooler are set up right. If everything’s fine, still get a solid PSU. Why would it drop to 11V?
