System shuts down unexpectedly due to abrupt power spikes even with backup power in place
System shuts down unexpectedly due to abrupt power spikes even with backup power in place
I've recently started having this problem. During sudden power surges, my PC restarts, no matter what I'm doing (gaming, coding, etc.). I have a UPS with enough power to spare, even with my maximum load. I first thought my UPS might have some issues, so I tried another one borrowed from a friend, but the same thing still happened. I've no clue where to begin troubleshooting this issue. My Hardware CPU: Ryzen 5 3600 (Stock cooler) RAM: Trident Z Royal 3600 MHz (8 x 2) Motherboard: MSI B450M Tomahawk Max GPU: MSI RTX 3060 12GB PSU: Corsair 650W 80+ Gold Case Fan: 3x 1st Player Firebase G3 Monitor: Gigabyte G24F2 Additional Load: 1 unit TP Link Deco M4 router. UPS: Marsriva MR-UF1250 1250VA Smart Line-Interactive UPS This is all the load I have on the UPS(don't know if it is the cause or part of the cause). Help Please..
I began examining the ground connections on all your circuits—it seems they’re not properly grounded. When issues arise, there’s nowhere safe to send stray current, which can then affect other devices, including your computer. The only situation that comes to mind is in an older home with bare aluminum wiring and no grounding. It became clear only after touching two devices at different outlets that something was amiss; the current flowed where it shouldn’t have, without any warning. My UPS only switched to battery backup during full power failures and didn’t offer any protection for my gear, resulting in data loss from hard drives in my NAS. It was a reliable APC 1500VA model I’d used consistently before, and once I relocated, the same problems persisted.
How much time has passed since you bought or replaced the battery in that UPS? These batteries usually last several years, but their power drops gradually. During testing, you can disconnect the power while your computer is running. I agree with another user that good grounding is essential for effective protection. It's also likely that repeated surges harmed the UPS's filtering system. However, since you tested with a different UPS, I'd suspect electrical issues first.
The quickest method is to visit a local hardware store and purchase an outlet tester. Plug it into various locations, including the UPS back panel, and record each outlet's condition. If any outlets show an open ground fault, it indicates a serious issue requiring professional electrician intervention to resolve. Although I might think I can handle this myself, I strongly advise against it for others.
