One of the problems that is difficult to detect in PCs is insufficient power supply. The symptoms may be the motherboard being "unusable", and software causing frequent system crashes. These symptoms may be manifested by abnormalities in the motherboard, CPU, or memory, and sometimes even appear to be problems with hard drives, CDROMs, floppy disks, etc.

Imagine that every component in a PC system has the same source of electrical energy - that is, the power supply. The power supply must continuously provide stable and continuous current to all devices. If the power supply is excessive or insufficient, the connected equipment may not function properly, appearing as if it is broken. For example, memory cannot be refreshed, causing data loss (resulting in software errors); And the CPU may deadlock or randomly restart; The hard drive may not rotate, or even more strangely - it may not be able to process control signals properly.

Computer power supply is the hub of power supply for various components of a computer and an important component of the computer.

Convert 220V AC power into DC power and deliver it to each component separately.
