GoKawiilUnplugging PCs during outages prevents damage from power-restoration surges
Electronics remain connected to home wiring even when powered off, leaving components like motherboards, RAM and SSDs exposed to voltage spikes that occur when electricity returns after an outage. These surges, which can exceed the standard 120-volt household level in the US, often cause more harm than the outage itself.
GoKawiil's interpretation of the reporting above, not reported fact.
Many people assume a shutdown PC is automatically safe, but the real danger comes from the surge when power is restored, not the blackout itself. Unplugging devices is a simple, free precaution that can prevent expensive repairs, data loss and the hassle of sourcing replacement hardware.
- Powered-off PCs are still vulnerable because they remain wired to the electrical grid.
- Power restoration surges are often more damaging than the outage itself.
- Unplugging devices during outages is a low-cost way to protect sensitive components like motherboards, RAM and SSDs.
