If you run a business in Townsville, you already know what storm season does to the power grid. Flickering lights, momentary outages, and full blackouts are part of life up here. But what you might not realise is the damage those power events are doing to your IT equipment — even when the power "comes back on fine."
When lightning strikes nearby or the power grid fluctuates, a surge of excess voltage travels through your power lines and into anything plugged in. Modern computers, servers, and networking equipment are sensitive to voltage spikes. A single surge can fry a power supply, corrupt a hard drive, or damage a motherboard — sometimes without any visible sign until the machine fails days or weeks later.
Even small, repeated surges that don't cause immediate failure degrade components over time. That computer that "just died one day" may have been slowly damaged by months of minor power fluctuations.
Most cheap power boards offer minimal surge protection — and many offer none at all despite being called "surge protectors." Even quality surge-protected power boards have limits. A close lightning strike can overwhelm them completely. And once a surge protector has taken a significant hit, its protection capacity is reduced — but there's no way to tell by looking at it.
A power board also does nothing for power outages. When the power drops, your computer shuts off instantly — no clean shutdown, no saving your work, no closing databases properly. This is how data corruption happens.
A UPS (Uninterruptible Power Supply) sits between the wall outlet and your equipment, doing two critical things. First, it filters and regulates the incoming power, smoothing out surges, sags, and noise before they reach your equipment. Second, it contains a battery that kicks in instantly when the power drops, giving you anywhere from 5 to 30 minutes of runtime depending on the unit.
That battery time isn't meant to keep you working through a blackout — it's meant to give you time to save your work and shut down properly, or for the power to flick back on (which it usually does within a few minutes during Townsville storms). For servers and NAS devices, a UPS can be configured to trigger an automatic clean shutdown if the battery gets low.
You don't need to put everything on a UPS — just the critical gear. For most small businesses in Townsville, the priority list is:
Definitely: Your server (if you have one), NAS/backup device, main workstation if it runs critical software, and your internet modem/router and network switch.
Nice to have: Reception computer, POS terminal, CCTV recorder.
Don't bother: Monitors (they're fine with a normal surge protector), printers, phone chargers.
Capacity (VA rating): A small desktop setup needs around 600-1000VA. A server and network gear might need 1500-3000VA. We can calculate the right size based on your actual equipment.
Type: For most office use, a "line interactive" UPS is the best balance of protection and price. For servers, an "online/double conversion" UPS provides the highest level of protection but costs more.
Runtime: Check how many minutes of battery you get at your expected load. For Townsville conditions, 10-15 minutes is usually enough to ride out a brief outage or shut down cleanly.
Software integration: Most business UPS units come with USB connectivity and software that can automatically trigger a clean shutdown on connected computers when the battery gets low. This is essential for servers that might be unattended during an outage.
A decent UPS for a single workstation costs $150-$300. A server-grade unit runs $400-$800. Compare that to the cost of replacing a fried motherboard ($300-$600), recovering data from a corrupted drive ($135/hr+), or the lost productivity when your whole office is down because the server won't boot after a storm.
We've seen Townsville businesses lose thousands of dollars in equipment and downtime from a single storm event that a $500 UPS would have prevented. It's one of the cheapest insurance policies you can buy for your IT.
We supply, install, and configure UPS systems for Townsville businesses. We'll assess your setup, recommend the right units, install them, and configure the automatic shutdown software so everything is protected before the next storm rolls in.
