9 best PC power supplies

Users who decide to assemble a computer themselves, first of all pay attention to the motherboard and processor to it, or vice versa. And it is right. But the most important thing is to choose the right PSU for the device. If this component fails, then others will burn. That is why it is necessary to approach the choice of a power device with all responsibility, because the work of the entire filling of the system unit depends on it.

How to choose

Before buying the best computer power supply, you need to study in advance what characteristics to select. It is recommended to approach this issue carefully, as the market is filled with a large number of products. And sometimes it’s difficult to choose something specific. But still there are certain characteristics that you should rely on when buying a power supply.

Type of PSU in the PC system unit

Power

Inexperienced users often make a simple mistake. Namely, they buy a device whose power coincides with the system to which the purchase will be connected in the future. But this is fundamentally wrong. Must be taken with a power reserve of 25-50%.

For example, for a PC with a video adapter in a single quantity, it is required to take a PSU of at least 550-750 watts. This is with the expectation that the computer will be used not only for simple operation, but also for games. In systems in which there is no video card or is very weak, you can put PSU with less power.

PSU power is indicated on the case

Efficiency

Any device must be selected for its efficiency. Since it is this indicator that indicates the effectiveness of the device in operation. The higher the efficiency, the better the device. It is recommended that you focus on an efficiency of 80% or more, since it is such an indicator that is characteristic of the best units for powering a computer.

Attention! For systems that operate on power below 500-600 watts, you can take PSU with a lower efficiency factor.

Which company is better

The market is filled with many brands that offer different power devices. On the one hand, this is good, because the buyer has a huge choice, but such a variety can bring the table down. It is necessary to choose a PSU from manufacturers who have taken leadership positions thanks to quality products. The best manufacturers of computer power supplies:
