Question Persistent High-Pitched Noise from PC Area (Even When Off)
Question Persistent High-Pitched Noise from PC Area (Even When Off)
Hello everyone, sorry for the lengthy update. I recently assembled my PC this week and while it performs well under load, I’m facing a persistent, bothersome high-pitched noise. It appears to originate from the PSU, GPU, or motherboard area, even when the system is completely powered down – this is definitely the source of concern. The sound is extremely sharp, resembling a tinnitus-like tone, and persists as long as the power supply remains connected. Once I disconnect the power cord, the noise disappears instantly.
Here’s a video that captures the issue:

Details about my setup:
CPU: AMD Ryzen 5 7600X 4.7 GHz 6-Core Processor
CPU Cooler: Thermalright Peerless Assassin 120 White
Motherboard: MSI B650M Gaming Plus WiFi Micro ATX AM5
Memory: TEAMGROUP T-Create Expert 32 GB (2 x 16 GB) DDR5-6000
Storage: WD Black SN770 2TB NVMe SSD
GPU: XFX Speedster SWFT 319 Radeon RX 6800 16 GB
Case: Lian Li A3 mATX
PSU: MSI MAG A650GL 650W 80+ Gold Fully Modular
What I’ve tried so far:
I’ve already sent the PSU back for replacement and received a new unit of the same model. However, the noise remains unchanged, leading me to suspect it’s not from the power supply. I turned off Global C-State Control in the BIOS to eliminate idle power-saving sounds, but that didn’t help. The disturbance occurs even when the PC is fully shut down, but ceases when I unplug the PSU.
Additionally, the sound spectrum shows a spike near 10 kHz – one at 0 (ORANGE) when the system is off, and another at 10 kHz when it’s running (RED).
Questions for you:
- Is this noise originating from another component, such as the motherboard or GPU, even when powered down?
- Have others encountered similar problems with comparable parts?
- Could the issue be linked to the power strip or wall outlet I’m using (I have a surge protector)?
I’m running out of ideas and would really appreciate any guidance or troubleshooting advice. Thanks in advance!
Standby 5V remains active all the time, but the power switch operates. Certain systems continue to supply notable power via USB ports even when off, only producing minor noise from the PSU or motherboard. You might attempt to identify the exact part and apply silicone as a dampener.
It is commonly used in electronic applications, often found at the base of capacitors, chokes, and coils to enhance stability. Usually white or gray, yet available in various colors. It is a temperature-rated silicone compound that is safe for plastics. You can purchase it from home improvement stores, automotive sections, or online where many choices are offered.

The concept involves using a vibrating object at an audible frequency; adding mass to it should alter that frequency. Localizing the sound can be done with advanced microphone arrays, or by touching a wooden dowel and feeling for changes in vibration. You may also place your ear against the dowel while in contact with objects to detect any variations in loudness.
