How to choose a power supply?

Power supply 500 watts refers to medium-power devices and is a kind of "workhorse" for most of the production systems.

When choosing a power supply, pay attention to the following nuances:

Models must be able to run the system with a real load rating of at least 400 watts. The model must have a strong 12V line and the correct setting of the protection mechanism, otherwise overloading can occasionally cause problems with voltage stabilization.
The noise level is of significant importance for many PC users. A reading of 50 dB or more makes the noise audible and annoying. 43-49 dB noise will be audible, but barely. Up to 42 dB the operation of the unit will not be heard at all.
Pay attention to the number of slots on the PSU: there must be not only the main power, 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 CPU power, 6 pin or 8 pin video card connectors, 15-pin SATA for drives, and main: 4-pin MOLEX type (in case there is an obsolete HDD with IDE interface or the same order disk drive, reobox or fan), 4-pin Floppy for floppy drives (these are rare).
The form factor is specified in the specifications of the case and it is this parameter that will help you find a PSU for 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 parameters are not necessary, but they are not unnecessary. These include: the presence of 80 PLUS certificate (the higher the certificate, the higher the efficiency is conditionally more); cooling system (passive - no fan, semi-passive - minimum fan speed to a heavy load), modular cable design (where they can unfasten and reconnect as convenient).
