Mouse noise
Mouse noise
Hello everyone!
I built my own desktop with an Asus TUF GAMING B560-PLUS WIFI and an MSI case. Everything looks fine. When I connect a Logitech G402 or a TUF Gaming Asus M4 Air mouse (both wired), I notice strange static inside the case. It’s not coming from speakers or headphones. I use a Fireface 800 audio firewire sound module and switch on every USB port for both mice. Then, when I connect a very cheap wired mouse, the noise disappears. I’m looking for advice on how to get better quality mice without compromising performance.
Identify the origin of the sound by using a cardboard tube or a rolled-up sheet of paper to listen closely inside the desktop. Position one end of the tube toward your ear and carefully direct it toward the direction where the noise appears. Examine the area around the I/O Panel. Locating the source is crucial.
Yeap! I found the source of the noise very accurately! The power supply. With the cheap mouse, the sound remains but much weaker—about 80% less intense, almost not noticeable.
The computer is drawing power from a UPS. When I connect a direct power line (220 V/50Hz), the noise (with the Asus mouse) is still present but quieter.
This is half the solution, so I’m open to more suggestions!
By "power source" you understand the PSU, correct?
Uncertain about the electrical connections you're referring to.
Usually it looks like:
Wall outlet (power) → UPS → PSU → Computer components (3, 5, and 12 volts) as needed.
What makes the UPS and PSU?
Make and model of UPS? PSU make and model? Age, heavy use for gaming, video editing, or even bit mining?
The power source is the wall outlet (220 V), with the UPS being a battery-powered device that supplies enough power to safely shut down the computer when the wall outlet fails. For whatever reason....
Are there other devices like surge protectors or power strips in the connection path?
Are there any additional devices connected to the UPS, surge protectors, and power strips?
Where are the mice being connected?
The answer refers to the power source as the PSU, correct?
Yes!
I’m not entirely sure about the electrical connections you’re explaining.
Usually it looks like: Wall outlet (power) → UPS → PSU → computer parts (3, 5, and 12 volts) as needed.
That’s all I need, nothing complicated!
What make and model of the UPS is?

What about the PSU itself? How old is it? Has it been used heavily for gaming, video editing, or even mining?
It’s brand new, just out of the box, like a baby!

The power source is the wall outlet (220 V), and the UPS runs on battery power to keep the computer running when the main power fails. For some reason...
Yes!
Are there any other devices in the connection path, like surge protectors or power strips?
Only a simple power strip with no buttons or surge protection. The two monitors are plugged in, but removing them didn’t affect the mouse noise.
Are there any additional devices connected to the UPS, surge protectors, or power strips?
Yes, an internet modem for fiber optic and IP TV.
Where are the mice connected?
Currently, they’re plugged into a USB2 port on the desktop backplate. I’ve tried connecting them to every available USB port, even the G19 keyboard with two ports, but it didn’t make a difference.
It might be an issue. I plan to switch the PSU in the coming days.
