PSU issue or something else?

I´m currently having issues with a brand new system ( 2 weeks old). .

So yesterday when i plugged in my new 165hz 32" IPS monitor and started a game i would start hearing an unhealthy loud vibrating sound (not a typical coil-whine sound) from the PSU ( i put a tube in my ear to hear that it acutally comes from the PSU and not the GPU or any other component). It ramps up when the GPU wattage goes up to 400 ish (under full load) and also when it goes down. I can´t hear anything under idle or inbetween.

This is super-frustrating as i can´t pinpoint if the issue is caused by the PSU or any other component causing something to vibrate in the PSU? Is my PSU too weak for my system? RMA?

loud vibrating sound from the PSU could indicate several possible problems, such as:


  • The PSU is positioned incorrectly, touching a cable, or vibrating because of its interaction with another component.


  • The computer needs more power than the PSU can deliver, and it's struggling to provide what's needed.


  • Something in the PSU is broken or impaired. With so many parts inside a casing that you should not open, a broken internal part of a PSU usually signals that a replacement is needed.


To stop the power supply from buzzing, you need to isolate the source of the problem, determine whether it's a danger, and then choose a solution that's best for your PC. Here are some steps you can try:


  • Locate the source of the sound. Make sure the sound is coming from the PSU and not from another component, such as the motherboard or graphics card. You can open the side of your case and listen carefully to each part.


  • Reposition and clean the PSU. Power down your computer, flip the PSU switch, and unplug it from the wall. After a few minutes, open the case and inspect in and around the PSU. Look for debris in the fan, look for anything touching the PSU that could vibrate with the fans. Check the screws holding the PSU. They should be evenly snug and not too tight. Use compressed air to clean the inside of your computer, starting at the top and working your way down. When you get to the power supply, blow the air directly on the fans to see whether they spin freely as you remove the dust from them.


  • Check your power consumption. Your system has some high-end components that require a lot of power, especially the GPU. Your PSU is rated at 1000W, which should be enough for your system, but it might not be delivering the full power or it might be faulty. You can use a power supply calculator to estimate your power needs and compare it with your PSU's specifications. You can also use a multimeter to measure the voltages of your PSU and see if they are within the acceptable


  • Remove any overclocking. If you have overclocked your CPU or GPU, you might be putting too much stress on your PSU and causing it to buzz. Try undoing your overclock and see if the noise goes away.


  • Replace the PSU. If none of the above steps work, or if you find that your PSU is damaged or defective, you might need to replace it with a new one. Make sure to get a high-quality PSU from a reputable brand that can handle your system's power needs and has good reviews from other users.
