Issue with Asus EZ tuning failing to boot
Hi,
I attempted to adjust the settings using Asus EZ Tune in BIOS on the Z390 tuf gaming board, not for the first time, but this attempt failed and the computer won't boot. I removed the battery for over five minutes and also performed a CMOS reset with shorting pins, yet nothing works. I only hear a click when pressing the power button, and the RGB lights are not on. The PSU is a SilentiumPC Supremo FM2 Gold 750W. Thank you for your assistance.
The PSU or the motherboard failed. Did you perform the PSU jump start test?
It appears PSU functions properly once adjustments are made, making the PC operational with fans running and cooling active. However, this happens only when the 8-pin connector is disconnected. Plugging it back in causes the PC to shut down again.
Found a comment by Tong Chang in a YouTube video discussing a faulty voltage regulator. The issue arises when the motherboard shorts while connecting the 4 or 8 pin CPU 12V ATX power connector, indicating the power supply is attempting to protect the CPU from shorting. A damaged VRM prevents stable voltage regulation, causing the power supply to cut off immediately to avoid further harm. It seems reasonable that the motherboard may need replacement, but I’d appreciate your thoughts on this.
This situation might actually be correct, but I'm unable to provide a definite response since there are no reviews available for the SilentiumPC Supremo FM2 Gold 750W. It's possible the PSU could be triggering the overvoltage or overcurrent safeguards, causing the system to cut power. Without more information, it's hard to say for sure. If you have another Z390 motherboard or PSU nearby, testing that could help narrow things down. If not, consider replacing the motherboard before addressing the PSU.
Thanks for the advice. SilentiumPC is quite popular in Poland with excellent user feedback, but it lacks OTP and OCP features. I'm unsure if this matters much. It has been functioning smoothly for over a year and a half under nearly continuous 24/7 CPU usage until I tried the EZ Tune method. Unfortunately, I don't have other components to test. I'll need professional assistance—I don't want to send each part directly to the manufacturer even though I still have warranty coverage. I'll update you once the problem is resolved.
Aye, keep us updated.

Updated, I purchased another motherboard, this one a Gigabyte Aorus Pro, but still faced issues. I connected the CPU cable, and the red CPU light on the motherboard became red, causing the PC to enter a bootloop. I bought a cheap Pentium Gold and everything functioned properly. It seems the Asus EZ tune for the i9-9900k may have been faulty. I wonder if Asus should refund me for the CPU? It was just the standard option in BIOS that I enabled.
