The power supply determines the health of the computer – will installed component enough current and whether it will stable.

Which power supply for the computer is better: selection criteria

Which power supply is better for a computer

When choosing a power supply for a computer, you should not start only on technical specifications and the amount needed connectors, but also from the following parameters:

  1. Manufacturers

  2. Certification

The producer of the ulterior motive is crucial when choosing a block power supply for computer. This is due to the fact that some companies indicate an overvalued power value of this device. how consequence, it will produce less current and will not be able to supply computer components. Therefore, you must choose a power supply with “honest” power.

Verified Manufacturers

Power Supply Manufacturers

Power supply manufacturers can be divided into two groups – proven, which produce quality devices with good power, and untested. With the latter may get lucky as well may not be lucky. But the power supplies from these manufacturers differ in low price.

These manufacturers include:

  1. Gigabyte ;

  2. Aerocool

  3. Fsp

  4. Chieftech ;

  5. Coolermaster ;

  6. Thermaltake


Gigabyte produces very reliable and at the same time inexpensive Power supplies. Their only drawback is that there can be a discrepancy between “advertising” and “real” power, and sometimes critical. So, for example, the model GZ-EBS50N-C3 advertised as a 500 watt. But actually its power 350 watts, as even written on the power supply itself.


Aerocool specializes in the production of cooling systems, therefore, its power supplies are far from perfect. Nevertheless, they are inexpensive and durable. And most importantly – their power is real, not just advertised.


FSP is one of the most famous manufacturers of power supplies. His products differ at the same time low price and good technical characteristics – from power to efficiency and durability. True, budget models usually do not offer any additional functions, but they completely fulfill their cost.


Chieftech is a manufacturer of very peculiar power supplies. FROM on the one hand – high real power, excellent efficiency, detachable cables on most models and optimal cost. On the other hand, the cooling system is not always worked out, which leads to a fairly high noise level, and a strange choice materials, resulting in wires in some configurations too tough.


Coolermaster produce some of the best power supplies. Gamer configuration, real power, low noise, detachable and flat cables, high quality capacitors, five years warranty and 80 Plus Gold certification – all about models from this company. There is only one drawback – the price. She may be too high.


Thermaltake – manufacturer of specialized power supplies for gamers. Products from this company are durable. highest power and attractive design. For example, a model Toughpower DPS S offers several specialized gaming features:

  1. Decorative RGB LED backlight;

  2. Controlling application for a computer with settings;

  3. Huge equipment;

  4. Several connectors for video cards;

  5. Very low noise;

  6. Detachable cables.

And also the efficiency of this particular model is more than 90%. Only the disadvantage of the device is too high a price. But if required power supplies specifically for a gaming computer, the best choice is Thermaltake products. Or Coolermaster, if the decorations are not are needed.


Certification of computer power supplies

There is indirect evidence of the quality of power supplies – standard 80 Plus. To get this certificate, manufacturing company must visit a special center testing and even pay for it. So the availability standard 80 Plus indicates that the manufacturer of the power supply ready to confirm the quality of their products to a third-party organization.

However, the 80 Plus standard is not so much about quality power supply, how much about its power consumption. The presence of this certificate means that the device has an efficiency of more than 80%.

There are several varieties of this standard:

  1. 80 Plus – Efficiency is 80%, power supply at 100% load saves 90% of power;

  2. 80 Plus Bronze – the efficiency is 81-85%, PSU at 50% load saves 90% of power;

  3. 80 Plus Silver – efficiency is 85-89%, PSU at 50% load saves 90% of power;

  4. 80 Plus Gold – the efficiency is 87-92%, PSU at 50% load saves 90% of power;

  5. 80 Plus Platinum – efficiency is 89-94%, PSU at 50% load saves 95% of power;

  6. 80 Plus Titanium – efficiency is 90-96%, retention tests no loads were carried out.

Standard 80 Plus without subcategory is designed for budget power supplies with low power, therefore tests for 100% load. But Bronze-Platinum are designed for more powerful devices designed for gaming computers. Therefore, it is advisable to test at 50% load.


It is worth remembering that there is only one standard 80 Plus. No 85 Plus etc. does not exist. Such marking is only marketing reception, and no more. As a result, for office computers it is advisable to use PSU with certification up to 80 Plus Bronze, for gaming – from 80 Plus Silver.
