Buying Guide: How to Choose the Right Power and Electrical Accessories for Computers

1. Power Supply Units (PSUs)

Ideal for desktop PCs, gaming rigs, and custom builds.

Key Considerations	Details
Wattage	Choose a PSU that provides enough power for your GPU, CPU, and peripherals (common sizes: 500W–1000W).
Efficiency Rating	Look for 80 PLUS certified units (Bronze, Gold, Platinum) for better power usage and heat control.
Modular vs Non-Modular	Modular PSUs allow you to connect only the cables you need — reducing clutter and improving airflow.
Form Factor	Ensure the PSU fits your case (e.g., ATX, SFX).

💡 Always allow 20–30% headroom in wattage for future upgrades or overclocking.

2. Power Cables & Extensions

Essential for connecting PCs, monitors, printers, and accessories.

IEC Power Cables (C13/C14) – Commonly used for PCs, monitors, and power supplies
Figure-8 Power Leads – For smaller devices like routers or laptop chargers
Extension Leads – Add more outlets with surge protection options
Cable Management Clips & Sleeves – Keep workspaces safe and tidy
Angled & Low-Profile Plugs – Useful for tight spaces or behind furniture

3. Surge Protectors & Power Strips

Protect against voltage spikes caused by storms, outages, or unstable mains power.

Type	Features
Standard Power Strips	Basic multi-outlet extensions
Surge-Protected Strips	Protect against energy spikes (look for joule rating)
Individually Switched Sockets	Turn off unused outlets to save energy
USB-Integrated Strips	Charge devices without additional adapters

✅ Choose surge protectors with a joule rating of 1000 or more and indicator lights to confirm protection is active.

4. Uninterruptible Power Supplies (UPS)

Keep critical devices running during power outages.

Ideal For	Use Cases
Home Offices	Protect PCs and routers during brief outages
Gaming Setups	Prevent loss of game progress or hardware damage
Business Servers	Maintain uptime and data integrity
Workstations	Save work and shut down systems safely

Key Features to Look For:

VA (Volt-Ampere) Rating – Determines load capacity
Battery Backup Time – Ranges from a few minutes to over 30 minutes
Automatic Voltage Regulation (AVR) – Smooths out voltage fluctuations
LCD Display – For real-time load and battery monitoring

5. Laptop Power Supplies & Adapters

Need a spare or replacement? Check:

Voltage (V) and amperage (A) match your original charger
Plug tip type – Proprietary (e.g., HP, Dell) or universal
USB-C PD (Power Delivery) options for modern laptops and devices
Travel adapters if using overseas

Expert Tips for Safe and Efficient Power Use

Avoid overloading sockets: Know your amp limits and spread power loads sensibly.
Label your cables for easier troubleshooting and organisation.
Use cable ties or sleeves to prevent tangling and tripping hazards.
Don’t daisy chain power strips — this can overload circuits and increase fire risk.
Regularly inspect cables for wear or damage, especially near connectors.
Turn off unused power strips to reduce phantom energy draw.
Upgrade to surge protection if you’re using standard strips — especially for computers and expensive gear.

Recommended Picks by Use Case

Use Case	Product Type	Features
PC Gaming	750W Gold PSU, UPS system	Reliable power under heavy load
Remote Work	Surge-protected power strip, USB-C laptop charger	Keep devices powered and protected
IT Setups	Rack-mounted UPS, modular PSU	Ideal for managing server uptime
Students	Compact extension lead, cable organiser	Space-saving and easy to manage
Home Office	Power strip with USB, cable sleeves	Tidy and efficient setup

FAQ: Computer Power and Electrical

What size PSU do I need for my PC?
Use a PSU calculator based on your components (CPU, GPU, drives, etc.) and add 20% headroom. Most gaming PCs need 600W–850W.

Is surge protection necessary for computers?
Yes, even minor power spikes can damage hardware or corrupt data. A surge protector is a simple, effective layer of protection.

What’s the difference between water-resistant and waterproof?
For outdoor or heavy-duty cables, waterproof means full protection from rain or spills, while water-resistant offers basic moisture protection.

Can I use a laptop charger from another brand?
Only if the voltage, amperage, and connector type match exactly. For USB-C laptops, Power Delivery (PD) support is essential.

What’s the benefit of a UPS over a power strip?
A UPS provides backup power during outages, while a power strip (even with surge protection) only filters voltage spikes.

Do I need a modular PSU?
Not required, but modular PSUs help with cable management and airflow in your case, ideal for clean builds.

How often should I replace power cables or strips?
Replace them if you see fraying, loose connectors, overheating, or if they’re over 5–10 years old without surge protection.
