Principle of surge protection for power supply units

Though they may not seem like the most delicate component in your machine, power supplies are still very much susceptible to voltage peaks and surges. Surge protectors specifically designed to protect power supply units can shunt the damaging excess voltage to your machine and keep your devices up and running without interference.

Surge protectors for power supply units protect your machines in many scenarios:

Lightning strikes
Overloaded circuits
Damaged wiring
