TOP 10 best power supplies for a computer: rating, specifications, user reviews


In the process of assembling any computer, special attention is paid to the power supply, since the correct operation of the remaining components depends on it. On the technical side, the power supply is a complex product, so choosing the best quality one is quite difficult, especially when the market is full of products from different competing brands.

For example, you can take a PSU with a power of 250 W and 400 W. The main technical indicator (power) in this case is different, but the price is the same. Why? In fact, it is impossible to compare such a complex device by a single criterion. That is why I recommend studying my article in order to know which power supply is better to choose, as well as read the opinions of reputable experts.

Rating of the best power supplies for a computer

Aerocool Cylon 500W

Due to its power and consistently high efficiency, confirmed by the 80 Plus certificate, this PSU will be an excellent addition to an office or home computer with an average level of performance. The rated power of the model is 500 watts. A (20+4)-pin connector is used to connect the main power, while the processor is powered from the (4+4)-pin connectors. A nice addition to the product is adaptive RGB backlighting with many preset modes. Thanks to the ability to synchronize with the motherboard, your system unit will be transformed and sparkle with bright colors.

I did not use this PSU in my assemblies, but a friend brought it to me for repairs (they spilled water). To be honest, the technical base inside is very good, and the fact that only one capacitor was damaged also speaks of the indestructibility of this little miracle.


An important feature of any system power element is its installation, which is carried out according to a special plan. About him, in fact, in this section will be discussed. The most important thing to know is that installing a PSU on your own is actually a fairly simple process that anyone can handle.

Here is a small action plan for installing a new power supply into the system unit:

  1. First, the computer should be completely disconnected from power, remove all side covers and place the case on its side.
  2. Further, if you still have an old power supply installed, you need to disconnect all the cables going from it to the motherboard, processor, SATA interfaces and other components, then unscrew all its fasteners and carefully dismantle it from the case.
  3. After that, we take a new PSU and install it in place of the old one, tightening it tightly with fixing screws.
  4. We connect all the necessary wires (to the video card, hard drive, processor, motherboard, front panel).
  5. The last step, if necessary, is to do a little modding of the computer, nicely organizing the space occupied by the cables.

What to look for when choosing

In this paragraph, we will consider the criteria that will once and for all help you decide which power supply to buy for your computer.

  1. Power. This parameter should be calculated immediately before buying a power supply, taking into account the individual characteristics of your components. There are special online calculators to help facilitate this process. Roughly speaking, a PSU with a power of up to 500 W is enough for undemanding office assemblies, a power of 500-650 W is enough for an assembly of average performance, and above 650 W for a gaming assembly.
  2. efficiency. This indicator indicates how much energy from the outlet will come to the components. Efficiency calculations are rather complicated, so it’s not worth “digging” somewhere in the jungle. You just need to know that an indicator above 80% is good, above 85% is excellent, more than 90% is the best possible.
  3. Element base. Analyzing this criterion, you can use a lot of incomprehensible terms, but I will not do this. You should know that a good technical base of the power supply will make its operation pleasant and long-term. Pay attention to the presence of capacitive capacitors that can withstand strong temperature changes, as well as branded resistors (for example, Japanese ones are of chic quality).
  4. Dimensions. Required parameter that will depend on your case. The most popular format is called ATX (it is the modern standard). Massive models are called Full- and Midi-Towers, and small-sized ones are called Mini-Towers.
  5. Cooling system. There are three types:
  • Active (constant rotation of the fan).
  • Semi-passive (at low loads the fan does not work).
  • Passive (no fan).

The first option is found in almost every PSU, and its most significant disadvantage is a strong noise level. The remaining options are rare and their cost is rather high, since the organization of fanless cooling requires the creation of a complex technical base. In general, here you should start only from your budget and preferences in terms of silence.
