Hey everyone, I could use some advice about an incident today. While my PC was running, there was a sudden power outage that caused a loud "POP" sound from my computer. When the power returned, I turned my PC back on, and everything booted normally. The BIOS settings were unchanged, I didn't notice any burnt smells, and there was no visible damage that I could see. Here are my specs:
- CPU: AMD Ryzen 7 9850X3D
- GPU: MSI GeForce RTX 5080 Shadow 3X
- Motherboard: Gigabyte X870E Aorus Elite WiFi 7
- RAM: Corsair Vengeance DDR5 6000MHz 32GB CL30
- PSU: ASUS ROG Strix 1000W 80+ Platinum
- SSD: Samsung 9100 Pro 2TB
- Cooler: Corsair Nautilus RS 360 AIO
- Case: NZXT H7 Flow 2024
After the incident, my computer booted up without issues. I ran a 15-minute OCCT Extreme CPU stress test, and there were no errors detected, with my CPU reaching a max temperature of 76°C.
I'm concerned that the power supply might have internal damage even if everything appears to work fine, and I'm wondering if the "POP" could have been a metal-oxide varistor responding to the power surge. Should I replace my PSU just to be safe? Is there a specific test I should conduct to check the PSU's health? I want to ensure my components are safe before using the PC regularly. Thanks for your help!

An audible pop can be alarming, but since your system is functioning normally, it may have just been the power supply reacting to the outage. The fact that you don't smell anything burnt is a good sign. If you're worried, running a dedicated power supply test can help ease your concerns. Just be cautious when determining if you need to replace it; you might not need to if everything's still operating smoothly.
It's tough to say exactly what happened. If your PC is running fine and you don't notice anything odd, just keep an eye on it for now. That "loud pop" could be due to a number of things—maybe a capacitor blew, or it could just be your power supply discharging. It might not hurt to invest in an uninterruptible power supply (UPS) to help protect your setup in the future.
