How do I choose a power supply?

The 500-watt power supply unit is a medium-power device and is a kind of” workhorse ” for most production systems.

When choosing, pay attention to the following nuances::

  • Models must ensure that the system operates with a real load rating of at least 400 watts. The model must have a strong 12 V line and the correct setting of the protection mechanism, otherwise overloading may cause problems with voltage stabilization from time to time.
  • The noise level is essential for many PC users. At values of 50 dB or higher, the noise becomes audible and quite annoying. 43-49 dB noise will be heard, but barely. Up to 42 dB, the operation of the unit will not be heard at all.
  • Pay attention to the number of connectors on the PSU: there must be not only the main power supply, 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 powering the processor, 6 pin or 8 pin connectors for the video card, 15-pin SATA for drives, and the main ones are: 4PIN MOLEX type (if there is an outdated HDD with an IDE interface or a disk drive, rheobas or fan of the same order), 4-pin Floppy for floppy drives (these are rare).
  • The form factor is specified in the case specifications, and it is this parameter that will help you choose the BC by height, depth, and latitude. Most 500-watt power supplies are standard.
