Power Supply or PSU is a component on a computer that serves to supply electric current to every other computer component that requires power. Given that a computer is an electronic device, the power supply is one of the most important components in your home computer. No matter how high the specifications of your computer, without a power supply it will not be useful and even cannot be turned on at all. If it can be likened to the power supply on a computer, it is the heart in humans.
Choosing a good power supply will extend the life of the computer we have. The higher the specifications of the computer, the higher the power requirements needed. Here are tips for choosing a good power supply:
- Estimate the amount of power required for your computer.
- Look for a power supply that has enough power to meet the needs of the computer. Higher is better.
- When looking for a PSU, don’t just choose a cheap PSU that is cheap, not necessarily good.
- Take a look at the PSU ratings that you get on the internet, how are consumer reviews of the PSU.
- Try to buy a PSU from brands that are already trusted in their fields, for example Seasonic, Digital Alliance, and many more.
- Look for one that already has a bronze stamp (at least), which is a certificate given to the PSU where the PSU is able to provide efficiency above 80. In addition, a PSU that has been labeled 80+ is also not a random PSU, the PSU must go through various stages in order to pass.
If you want high quality, you definitely have to drain your wallet a little deeper because the quality is comparable to the price. Here are the characteristics of a quality power supply:
1. The price is quite expensive.
For 350 Watt the price ranges from 400 thousand, 400 Watt the price ranges from 450 thousand to 500 thousand, while for 500 Watt the price ranges from 600 thousand to 850 thousand. For a larger wattage, the price is certainly more expensive. This high price is a compensation for components that do have good quality and are more durable.

2. Heavy power supply is more than ordinary power supply.
Physically, the weight of a good power supply is heavier than a normal one. This is because a good power supply uses selected materials, for example the cables have thicker copper fibers, the capacitors in them use more capacitors, and the coils of the wires have more coils. In addition, a good power supply usually uses a layered cable which is often called cable sleeving.
3. Have UL Number
The UL number is a sign of the manufacturer of a power supply. By knowing the identity of the power supply manufacturer/factory, we can find out whether the product qualifications are internationally certified.
