Are you experiencing issues with your PSU?
Yeah, that's the Tier A unit. Review: I recommend sending in a return for replacement (RMA). It might be due to some defects, which is why it comes with a 10-year warranty. After getting the new one and still facing the same problems, consider other possibilities: - MoBo VRMs - Are you using a power strip where the PSU's power cable plugs in? - Are there other high loads on your home electrical network (to determine why the circuit breaker tripped)?
You mentioned using a CM PSU for a year. Did the reboots or shutdowns begin right after installing it, or later? Also, what caused them to start after installation?
If there’s a problem with the PSU, there doesn’t seem to be any clear reason why the issues appeared; they could happen at any time, not just when you first started using the PSU.
This setup isn’t ideal. A direct connection to the wall would be better, but most sockets are single-pole, so a power strip is necessary.
In this situation, the problem likely points to the PSU itself. The circuit breaker may trip due to overloads or short circuits, and a faulty PSU can also trigger that breaker.
You said you can’t borrow a PSU to check for faults, so the only solution is to purchase one. If you need it, consider the Corsair RMx. This way, you can confirm the PSU’s condition and keep your CM unit operational during repairs.
The problem began a few days ago and has persisted for over a year. It only occurs when trying to power on the PC, causing it to restart repeatedly after 15 attempts. After waiting 30 minutes, the system becomes stable. When the PC is turned off, a crackling noise emerges after about 10 seconds, appearing only when the device is plugged in but not powered on. The noise disappeared after two days once the PC was connected. The link provided details this issue: https://drive.google.com/file/d/1iFL3Wsg...p=drivesdk
The brief "crackling sound" might indicate internal components within the power supply unit overheating. Avoid using this unit again. A very quick initial surge of power from an ATX PSU can surpass 80A and often triggers breakers or fuses. Refer to the source: Inrush current, also called a switch-on spike, describes the peak instantaneous current drawn by an electronic device when powered on. The APFC capacitor charging demands cause substantial inrush when the PSU starts. Excessive inrush can lead to breaker trips and potential harm to switches, relays, and bridge rectifiers. Therefore, minimizing the inrush current at startup is ideal.
I wasn't aware of inrush current in PSUs, thanks for the details.
Just a quick note, the new PSU has arrived and my PC is working again thanks to the guide everyone provided.
Updating your BIOS to the newest version would be beneficial now that you've installed the new PSU.
