Top 6 Best Surge Protector for Gaming PCs

What to Look For in a Gaming PC Surge Protector

Check the following specifications when choosing a surge protector for your gaming PC:

Number of Sockets

Count the devices you need to connect and choose a surge protector with enough sockets for them. This avoids running out of outlets or compromising safety.

A multi-plug extension lead adds cost and takes up more space. Work out how many sockets you need before buying your gaming PC surge protector.

EMI/RFI Noise Filtering

EMI = Electromagnetic Interference, while RFI = Radio Frequency Interference. These terms are sometimes used interchangeably, although they have different technical meanings. They can be treated alike for gaming PC surge protection.

Filters such as low pass filters, high pass filters or band pass filters allow only certain frequencies through. A set range of EMI/RFI emissions therefore reaches the protected device.

Certain EMI/RFI emissions do not interfere with the operating frequencies of different electrical and electronic devices.

EMI/RFI noise filtering aims to remove electromagnetic and radio frequency interference that affects gaming PC surge protection.

Look for EMI/RFI emissions in the gaming PC surge protector’s specifications.

Warranty

A long warranty provides coverage and indicates the manufacturer’s confidence in the surge protector’s quality.

Suppliers would struggle to stay in business if they gave long warranties on gaming PC surge protectors that failed after 2 weeks.

Look for longer warranties and high insurance payouts from a company that has been around for more than five years.

Safety Rating

For gaming PC surge protectors, check for UL certification from Underwriters Laboratories as a safety endorsement.

UL is one of several companies authorized to carry out security screening by the U.S. federal agency Occupational Safety and Health Administration (OSHA). OSHA has a list of authorized testing labs, which are acknowledged as Nationally Recognized Testing Laboratories.

UL has several safety standards. For gaming PC surge protection, look for compliance with UL 1449.

UL 1449 is the Underwriters Laboratories Safety Standard for Surge Protective Devices (SPD), which applies to gaming PC surge protection.

Check that your gaming PC surge protector conforms to UL 1449.

Joule Rating

The joule rating tells you how much energy the surge protector can absorb. A higher rating provides better protection.

The required joule rating depends on what you want to protect, whether that is a PC, a gaming PC or a whole house.

Here are some rough joule rating guidelines:

A system with up to 1000 joules of surge protection suffices for little electronic devices.
A surge protector with 1000 to 2000 joules will supply sufficient protection for office devices and power tools.
Consider the highest joule rating (2000+) for expensive gaming consoles, home theater systems and any computer that stores important information. This applies to expensive or irreplaceable equipment.

For a gaming PC, look for a surge protector rated above 2000 joules.

Diagnostic LEDs

Diagnostic LEDs let you check whether your gaming PC surge protector is working.

Choose diagnostic LED lights that show power, protection and line fault status at a glance.

Clamping Voltage

Clamping voltage is the threshold at which the surge protector blocks excess voltage. A lower threshold provides better protection by limiting the voltage that reaches your gaming PC.

An excessively high clamping voltage lets too much voltage reach the gaming PC and damage it.

Before buying, check your gaming PC’s maximum rated voltage. The surge protector’s clamping voltage must be LOWER than the PC’s maximum operating voltage.

For a gaming PC surge protector, the general recommendation is a clamping voltage of LESS than 700V.
