Motherboard operates at reduced power levels
Motherboard operates at reduced power levels
Hey, I noticed a problem about a month ago. After checking with hwinfo, I found that the power supply voltage is normal, but the motherboard displays 10V instead of the expected 12V. Every day I experience a black screen or a reboot with kernel-power id 41. It seems completely random—could be playing games, watching videos, or browsing. Nothing unusual happening.
System specs:
- Ryzen 2700X
- Corsair Vengeance 8x2GB 3000MHz case
- ASUS X470 Prime Pro
- RTX 2080 Ti (Furball)
- H115i Pro RGB (with 2 Noctua 3000RPM PWM fans)
- Corsair HX1200i Platinum
- Cougar Panzer Evo RGB full tower
- 2x Samsung 500GB SSD + 2x 2TB HDD
What I tried:
- Ran Memtest 12-hourly, no errors in both sticks and single stick
- Used three different GPUs in different PCIe slots
- Tested two different power supplies
- Reinstalled Windows with minimal apps
- Updated all drivers from the official site, using latest BIOS and GPU with DDU
- Verified all cables were plugged correctly
- Set Ryzen balanced plan, keeping everything powered and max settings
I think the issue might be with the motherboard itself. Please find my hwinfo reading for reference. Any advice would be greatly appreciated.
It seems like you're dealing with a tricky issue—maybe the motherboard isn't working properly, or you could upgrade your drivers and Windows. Stay tuned for more updates from GLHF Zuccers!
It seems like either a data issue or a hardware concern in BIOS regarding 12V readings. Have you confirmed the voltage at the connectors on the motherboard using a multimeter? It might be wise to proceed with an RMA if the readings don’t match expectations.
Bios readings match the hwinfo values. I plan to check the voltage tomorrow with my friend using a DMM. The same measurement appears on both power supplies (850mA and HX1200i). The board arrived in September, but about a month ago it began failing—first with the RTX 2080 Ti, then with the 1070 after switching to it. I was surprised when it stopped working again, wondering if the new card caused the issue or if something damaged the board.
It seems the issue might relate to voltage regulation or sensing on the motherboard. Checking the input values will confirm this. If it receives 12V but only displays 10V in software/BIOS, the board is likely faulty. I encountered a similar problem with a Chevy where the Body Control Module reported 13-14V but showed 18V, causing the remote start to disable due to false readings. It could be the board activating voltage protection when it detects an unexpected low voltage, shutting down the system.
Likely the voltage regulator failed. A new board is coming (ASRock X470 Taichi). I plan to return the Prime Pro or request a refund if they accept it. The ASUS return process is too slow, and I can't stay without a PC for over a month.
