How to Test Power Supply?

Mostly there is an uninterrupted power supply system (UPS) to enable power backup if the power supply fails.

A modern UPS system is also capable of protecting several power outages that the company's sensitive equipment can often withstand.

This sensitive equipment is also known as critical loads These critical loads are classified as any UPS installed to protect against damage in the event of a power outage. Each critical load is different and varies depending on the activities of the company or organizations. 

They are often data centers for storing or processing company or customer data. If these systems are damaged the company may be at serious risk of failing in its operations.

Without a UPS system, there are many electrical risks to these critical loads. Check the main working SMPS or power supply problems to protect against on your pc or computer are as follows


These are classified as a complete loss of power to a system that can last from seconds to hours. If a power outage occurs the UPS is located to provide power backup for continued operation of the systems. 

If there is no system in the system protection the blackout can cause severe damage to the hard drives and lead to data loss.


Spikes can be large and strong and therefore very harmful to both hardware and software systems. Spikes occur due to rapid voltage transitions placed on top of the SMPS or power supply of the test systems. 

They are often caused by a lightning strike in the local environment or if other electrical equipment replaces high electric currents.


These occur when you do not check the working SMPS or power supply drops below its normal levels on your pc or computer for a short period. 

They tend to happen when a system on-site with high power consumption is turned on and can cause power outages throughout the system.

Power surges

Power surges are the opposite of power outlets Occurs when a large power system is turned off. 

This causes the voltage to rise above its normal level for an extended time and may damage the PSU or power supply components in the test system if you do not check its health.


Just like sags A power outage is the result of a decrease in power to the main supply but can last longer. 

They occur if the main SMPS or power supply for the test system experiences a high demand for electrical output and is required to reduce the amount of voltage supplied to its network.
