The power supply provides electrical current to all of the computer components. The power supply unit must have sufficient power to supply the various peripherals of the latter.
It converts the 230 V alternating voltage into various direct voltages used by the motherboard and peripherals (hard disk, GPU, CPU, etc.). Even though a 350 watt power supply is not being demanded as it was 10 years ago, there is still some use of it for low-end, business computers.

Conclusion
In general, the power supply unit is a switching power supply type converter , combining lightness, high efficiency and compactness. On the other hand, this type of power supply generates a lot of high frequency interference, more or less well filtered by the metal or metallized boxes forming a Faraday cage and the input and output filters.
Different Power Supply voltage by Regions
In the United States, power supplies receive a voltage of 110 V and 60 Hz, while in Europe the standard is 230 V at a frequency of 50 Hz; this is the reason why power supplies usually have a switch to choose the type of voltage received.
How to Choose the Right Wattage for my PC?
“Why am I being told that my PC will consume only 300Watts and I am being told to buy a 550/600Watts power supply?”
The efficiency of a power supply is between 50/60% of its load, so a PC configuration consuming 300Watts, you will be directed to a 500W power supply. That’s very important because the power supply can harm all your PC components. It also protects your PC from certain under voltage or electricity current breakdowns. If you want to buy a higher watt PSU, check out our best 700 – 750 Watts Power Supply list as well.
