Symptoms
- Faint high-pitched hum near the power area
- Buzzing gets louder under heavy graphics load
- Noise changes with brightness or screen content
- Power brick feels warm alongside the noise
Likely causes
- CommonCoil whine, a common minor electrical humOften normal and harmless, caused by tiny vibrations in electrical components.
- PossiblePower supply nearing end of lifeAging capacitors can cause louder or changing buzzing.
- PossiblePoor quality or damaged power cableCan cause unstable power delivery and noise.
- PossibleExternal power brick overheatingHeat can worsen electrical noise from internal components.
- Less commonInternal capacitor failureA more serious fault that risks further damage if ignored.
What to do
- Listen closely to identify whether the noise is a faint constant hum or a loud, changing buzz.
- Check if the noise scales with graphics load, which often points to normal coil whine.
- Make sure the power brick or console has open airflow and isn't covered.
- Try a different power cable to rule out a cable-related cause.
- Feel the power brick for excessive heat; if it's very hot, unplug and let it cool.
- If the buzz is faint and doesn't change or get worse over time, it's likely safe to ignore.
- If the buzz grows louder, is accompanied by a burning smell, or the unit gets very hot, unplug it and have it inspected.

When to call a pro
A loud or worsening buzz paired with heat should be checked by a repair technician rather than continuing to use the console.
Safety
Use caution
If the buzzing is loud, growing worse, or paired with heat or a burning smell, unplug the unit immediately and have it inspected before using it again.
