Question My USB keyboard and mouse disconnect/reconnect whenever the UPS makes electrical noises?
Over the past few days, my USB keyboard and mouse reconnect after UPS powers on, accompanied by electrical sounds. This appears linked to voltage changes, especially with recent power outages. Turning off power to the UPS resolved the issue temporarily. While playing Elden Ring, similar problems occurred, causing GPU and screen freezes for a few seconds. Typing letters would result in rapid spam until reconnection. Occasionally, both devices emit USB connection sounds, and they both have RGB lighting. I’ve disabled the "suspend power to USB" option for all USB ports and recently updated my Logitech mouse. Another occurrence happened when using alt+tab. Could anyone explain what’s happening with these devices?
System details:
Processor: AMD RYZEN 5 2600 6 core 3400 MHz
Baseboard: ASUSTeK EX-A320M-GAMING
RAM: 32 GB
GPU: gtx 1080
UPS details requested: make and model, age, usage in areas with frequent outages or voltage changes. Previous battery replacements. Other surge protectors or power strips in use. System information needed: PSU specifications, age, condition, and your response to voltage fluctuations. How do you handle playback during instability—continue using it or switch to a standard shutdown method?
Psu: Circle CG Raw Power 650W SMPS 650 Watt 80 Plus Bronze Certification Modular PSU With Active PFC
I purchased it new in 2019.
Case: CIRCLE ELEGANTOR (ATX) Mid Tower Cabinet - Includes Transparent Side Panel (Black-Red)
Upgrades: elnova private limited, model T1002.
It should be around 5 years or newer. It contains two batteries that have not been replaced. I don’t add any extra components.
I’m based in India and power instability is frequent. I often keep playing for a short time. Sometimes during intense sessions, the PC shuts down completely. This happened about two months ago.
The recent USB reconnection took place roughly three days ago.
My first sign of trouble occurred while playing Ffxiv. I kept playing until it stabilized in just four seconds.
There’s a record of a damaged fan control wire near the middle. It happened months after my PSU purchase in 2019. The wire was internal and connected to the front fan control panel of the case. The issue appeared to be faulty wiring. It was thrown away and removed.
Initial thoughts:
The PSU might be approaching its end of life, likely beginning to weaken, particularly when sudden increases in wattage are encountered.
Secondly, continuing to play during power issues and pushing the system until it stops could lead to file corruption.
Third, removing the damaged wire might have disrupted cooling or introduced other complications.
Fourth, whatever triggered the burned-out fan control wire may still pose an unresolved issue.
What to do:
Computer
Power off, unplug, and open the case.
Clear dust and debris from inside.
Verify that all connectors, cards, RAM, and jumpers are securely positioned.
Check for additional damage signs: melted insulation, exposed conductors, discolored or blackened parts, swollen components, bent wires, missing screws, cracked fan housings or blades, corrosion, leaks.
Do not open the PSU – there’s nothing within it that can be repaired safely.
Files
Execute "sfc /scannow" and "dism" to fix corrupted files.

UPS
Review the UPS manual. Confirm it’s operating properly. If it has endured many power surges, surge protection might be compromised.
Continuing to play games while electrical disturbances occur could worsen damage if a surge reaches the PSU or computer.

Still, I think the PSU is the most probable cause.
Do you know anyone who could lend you another PSU for testing? (Family, friend, coworker?)
If you try a different PSU, make sure not to mix cables from other units.
Lastly, always back up critical data at least twice, storing copies in separate locations away from the computer.
Future power fluctuations might exceed what the UPS, PSU, and system can handle. This could lead to serious consequences.
I'm considering purchasing a voltage stabilizer to help avoid accessory disconnections. Would this be useful? Or is the issue mainly related to the power supply unit? I've observed that reconnecting problems occur only during noise from the ups. I've inspected the motherboard connections and found them to be fine. Even when I turn off the main power, the ups switch immediately to battery mode without any disconnections.
It's also impacting my monitor. After connecting my PS4 and monitor for an update, every time the ups produces a clicking noise, the screen shuts off and then restarts.
I'm just emphasizing that choosing a gold-rated option provides superior components compared to bronze-rated ones, especially considering the PSU's low quality.
You might find high-quality bronze-rated PSUs, but they are much harder to locate than gold-rated ones.
Just because something works in certain situations doesn't mean it's a strong argument.
Gigabyte offers some gold-rated models that have been causing issues.
There are also many questionable manufacturers that misrepresent their efficiency by using fake samples or badges, hoping people will accept the claim of being gold rated.
Relying on a product's advertised efficiency rating as a quality indicator is simply poor or careless advice.
Who exactly awarded it this "gold rating"? There are a LOT of fakes.
