2023年6月9日 · PSU stands for Power Supply Unit, and it is the part of a PC responsible for converting the alternating current (AC) power from an electrical outlet into direct...

A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.

2023年7月28日 · The power supply unit is the piece of hardware that converts the power provided from the outlet into usable power for the many parts inside the computer case. It converts the alternating current from your wall outlet into a continuous form of power called direct current that the computer components require.

2023年12月20日 · Power Supply Units (PSUs), despite their name, transform power rather than providing it to systems. In particular, a power supply regulates the DC output voltage to the precise tolerances needed for contemporary computing components in addition to converting the alternating high voltage current (AC) into direct current (DC).

Simply put, a Power Supply Unit (PSU) is an electrical device that converts alternating current (AC) from the wall outlet into the direct current (DC) that your computer components require to operate.

2025年2月8日 · The acronym PSU stands for Power Supply Unit, which is a critical component in electronic devices such as computers, laptops, and televisions. In this article, we will explore what PSU means, its functions, and its importance in modern technology.

2024年5月30日 · A Power Supply Unit (PSU) is a crucial component of a computer system that converts electrical power from an external power source into usable power for the

2024年7月30日 · A PSU is a critical component of your computer system. The electricity from your home or office outlet typically uses an alternating current (AC) and comes in at a high voltage. Your PSU converts this to the lower-voltage direct current (DC) …

The abbreviation PSU commonly refers to a Power Supply Unit, which is an essential component in electronic devices that supplies power to the system by converting electrical energy from an outlet into usable power for the internal components.

2023年11月29日 · PSU stands for Power Supply Unit, a crucial component of any electronic device that regulates and supplies power from the main source to ensure proper functioning and avoid damage. Discover its importance and how it works.
