Quick Answer

Power outages corrupt data when your PC drops power mid-write, leaving partial files, broken databases or damaged Windows updates. The fix is layered: a properly sized UPS, frequent automated backups, and SSDs with power-loss protection where the work matters. For SA users, that combination is no longer optional given loadshedding's unpredictability.

Why Loadshedding Wrecks Data

When the lights go off, anything currently being written to disk is at risk, database transactions, open Photoshop files, Word docs in mid-save, even Windows itself if it was patching. SSDs without power-loss protection can lose their internal mapping table, making files unrecoverable even though the drive still appears healthy. NVMe drives in particular are vulnerable because they cache writes aggressively for speed. The kicker is that many SA homes don't just suffer one clean outage, voltage spikes on the way back can corrupt data on the second hit.

Buy a UPS Sized for Your Setup

A UPS is the single most effective defence. For a typical SA gaming rig pulling 500-650W, a 1500VA line-interactive UPS gives you 8-15 minutes of clean shutdown time. Office or studio setups with multiple monitors need 2000VA or larger. Avoid the cheapest standby UPS units, they often pass a millisecond gap that's still long enough to crash a desktop. Evetech stocks Mecer, APC and CyberPower units in ZAR with quick local delivery, and most pair them with surge protection on the input side.

Backup, Power-Loss Protection and Recovery Habits

Pair the UPS with a real backup routine. Use Windows File History or Macrium Reflect on a daily schedule, plus a cloud sync like OneDrive or Backblaze for off-site copies. For workstations doing video editing or database work, choose an SSD with power-loss protection, enterprise drives from Samsung, Kingston and Micron carry it, and it preserves in-flight writes by flushing to NAND during a power loss. Finally, never run Windows updates or BIOS flashes during stage 4 or 6 loadshedding windows.

Frequently Asked Questions

How long should a UPS run my PC during loadshedding?

Aim for at least 10 minutes of runtime under load. That's enough time for the UPS to signal Windows to shut down cleanly, even if you're away from your desk when the power cuts.

Will a UPS protect against surges when power returns?

A line-interactive or online UPS with built-in AVR will handle most return-of-power surges. For full protection, plug the UPS into a quality SA-spec surge protector strip rated for at least 1000 joules.

Is Evetech's UPS range available with delivery in SA?

Yes, Evetech ships UPS units across South Africa with next-day delivery to most metros, and pricing is in ZAR with no hidden import surprises.
