FAQs

1. What is a power supply unit?

A power supply unit (or PSU) is an internal hardware device that converts the main alternating current (AC) into the direct current (DC). The power supply units convert the alternating current of 110-240V into low voltage DC. 

Every power supply has a scale of efficiency, from 80 plus to Titanium. 80 plus means the power will be converted with an efficiency of at least 80%. When the rankings go up to 80 plus platinum or titanium, the efficiency can be up to 94% (at 50% load). The most suitable power supplies for individual PCs or computers are 80 plus silver and below. 

2. What are the components of a power supply, and how do they work?

A power supply unit contains 4 main basic components: transformer, rectifier, filter, and voltage regulators.

  • Transformer: The transformer is a static device that transfers the power from the primary to secondary winding without affecting frequency. Its purpose is to increase or decrease the AC voltage level and isolate the rest of the electronic systems from the AC mains.

  • Rectifier: changes the AC power into pulsed DC. The basic rectifier is diode. The diode works as a rectifier in the forward direction.

  • Filter: prevents the outputs from ripple components. The filter is designed to convert pulsed DC from rectifier circuits into a suitable smooth DC level. There are two basic types of PSU filters: capacitive filters (C-filters) and resistor-capacitor filters (RC filters). 

  • Voltage regulators: aims to provide stable and well-regulated DC output voltage. This stability is kept at any level of input voltage. 

3. Should you repair broken power supply units?

In many countries, restrictions on the law prevent people from attempting to open, re-use, or repair PSU. All you are able to do is to change the fuse (in case it’s easily accessible). If not, please buy the new one.

Even when you’re an expert, it’s not 100% sure that you can fix it. The hidden issues are so dangerous that they can burn your house in the future. Therefore, the fastest and safest way is to buy a new PSU.
