Computer Surge Protectors

Computer surge protectors are a critical yet often overlooked part of any home or office setup. Designed to defend your devices against unexpected voltage spikes, surge protectors help prevent damage to sensitive electronics, data loss, and hardware failure. Since 1988, we’ve been helping customers protect their computers, peripherals, and networking equipment with high-quality surge protection that’s reliable, tested, and built to last.

Whether you’re a casual user, gamer, remote worker, or IT professional, our carefully selected range of surge protectors ensures that your tech investments are safe, secure, and always connected.

Why Use a Surge Protector for Your Computer?

Electrical surges can be caused by lightning, faulty wiring, power outages, or appliance cycling, and even small spikes can degrade internal components over time. Surge protectors:

  • Shield computers, monitors, and accessories from voltage spikes

  • Extend the lifespan of your electronics

  • Provide multiple outlets in a single unit

  • Offer USB charging and power management features

  • Reduce fire and shock risks from overloaded circuits

Unlike standard extension cords, a surge protector is designed with internal components that absorb or divert excess energy, keeping your devices safe.

Buying Guide: How to Choose the Right Surge Protector for Computers

1. Look at the Joule Rating

The joule rating indicates how much energy the surge protector can absorb before it fails.

Protection LevelJoule Rating
Basic400–999 joules (light-duty use)
Moderate1000–1999 joules (standard home/office use)
High2000+ joules (gaming PCs, professional equipment, or multiple devices)

💡 The higher the joule rating, the better the protection against powerful surges.

2. Check the Number and Type of Outlets

  • Standard AC Outlets (UK Plug) – For computers, monitors, printers

  • USB Ports (Type-A / Type-C) – Charge phones, tablets, and peripherals

  • Wide-Spaced Outlets – Accommodate larger power adapters

  • Individually Switched Sockets – Control power usage and save energy

  • Right-Angle Plugs – Fit easily behind desks or furniture

3. Confirm Surge Protection Features

FeatureBenefit
Clamping Voltage (VPR)Lower is better (around 400V–500V is ideal)
Response TimeFaster response (nanoseconds) means better protection

Expert Tips for Using Surge Protectors Effectively

  • Never daisy-chain surge protectors (don’t plug one into another) — this can cause dangerous overloads.

  • Check the indicator light regularly — if it’s off, the surge protection may no longer be active.

  • Avoid moisture — keep surge protectors off the floor and away from water sources.

  • Label your plugs if using multiple strips, especially in shared setups.

  • Replace every 3–5 years or immediately after a major surge — they don’t last forever.

  • Don’t rely on surge protectors for lightning strikes — use whole-home surge protection if needed.

FAQ: Computer Surge Protectors

What does a surge protector actually protect against?
Surge protectors guard against power spikes and surges, sudden increases in voltage that can damage sensitive electronics.

How do I know if my surge protector is still working?
Most have an LED light that indicates protection is active. If it’s off or flickering, the internal components may be spent.

Is a power strip the same as a surge protector?
No. Many power strips only provide extra outlets, not surge protection. Always check the product description for joule rating or surge protection features.

Can I plug a printer or speaker system into a surge protector?
Yes, just make sure the total power draw doesn’t exceed the strip’s capacity (usually listed in amps or watts).

Are surge protectors necessary for laptops?
Yes, especially if you’re using a laptop docking station, external monitor, or peripherals. Laptops can also be damaged by power fluctuations when charging.

How long do surge protectors last?
Typically 3–5 years, depending on usage and the number of surges absorbed. High-end models may last longer, but should still be inspected regularly.

Do I need a surge protector if I use a UPS?
Most UPS systems include built-in surge protection. However, if you’re plugging other devices into separate power strips, those should be surge-protected.
