TOP 10 best 500W power supplies for a computer: rating 2024-2025 and recommendations on how to choose a model

Without a power supply, a personal computer is like a boat without oars.

The range of 500-watt blocks on the modern market is wide, in addition, it is regularly updated.

And even an experienced user can sometimes find it difficult to figure out: is this or that option worth your money? Are there any unnecessary "bells and whistles" and vice versa - is there enough for normal work?

How to choose a power supply?

The 500-watt power supply is a mid-range power supply and is the workhorse of most production systems.

When choosing, pay attention to the following nuances:

Models must ensure the operation of the system in the presence of a real load indicator of at least 400 watts.The model must have a strong 12 V line and the correct setting of the protection mechanism, otherwise, due to overload, problems with voltage stabilization may occur from time to time.
The noise level for many PC users is essential. At values of 50 dB and above, the noise becomes audible and pretty annoying. 43-49 dB noise will be heard, but barely. Up to 42 dB, the operation of the block will not be heard at all.
Pay attention to the number of connectors on the PSU: there should be not only main, but also additional power. For example, to connect at least one third-party external drive or another video card. The main connectors are ATX 24 pin, 4 pin or 8 pin for processor power, 6 pin or 8 pin connectors for a video card, 15-pin SATA for drives, and the main ones are 4pin MOLEX type (in case you have an outdated HDD with an IDE interface or disk drive, reobas or fan of the same order), 4-pin Floppy for floppy drives (these are rare).
The form factor is indicated in the characteristics of the case and it is this parameter that will help you choose the BC in height, depth and width. Most 500 watt PSUs come standard.

The above parameters are the main ones that you should definitely study before buying. Additional - not required, but will not be superfluous. These include: the presence of an 80 PLUS certificate (the higher the certificate, the more efficient it is conditionally); cooling system (passive - without a fan, semi-passive - minimum fan speed to heavy load); modular design of cables (when they can be unfastened and reconnected as convenient).
