15 best power supplies

Inexpensive power supply, which belongs to the rebranded line with an emphasis on environmental friendliness that is fashionable today. On the 12-volt line it produces 456 watts. He left a double opinion about himself on the market, as some consider it very quiet, while others find it too noisy. In the second case, only manual modification and replacement of the fan with some version from Zalman will save. Suspiciously light in weight, although everything you need is inside in full.

There are some downsides, including some significant ones.For example, cables do not have a braid, and the component base quickly becomes unusable over time, which causes drawdowns. Probably as some kind of compensation, the unit can be disassembled and cleaned very easily, which means it will fit into the office and work PC without any problems.

The popular "old man", released back in 2014 and still in demand. The model is not without flaws, but on the whole it performs well, has an active power factor corrector, an increased number of SATA cables, an additional connector (8-pin) for powering the processor and compliance with the 80 PLUS Standard certificate. Note the presence of braided wires and a 5-year warranty from the manufacturer, which is not very common on the PSU market.

On the other hand, judging by the reviews, the power supply often dies in the fourth or fifth year, i.e. does not always work out its declared service life. At the same time, such cases are more common when the PSU was used to build a gaming PC, i.e. worked not under office load, to which it is much better adapted. Among other disadvantages, we highlight the possible presence of an unpleasant smell of burnt plastic in the first weeks of operation.

The model is on the verge of moving into the mid-budget segment, but it justifies its price, and it is cheaper than schematic analogues, for example, from Zalman or Be quiet!. This power supply has a high reliability design, which affects the service life and the effectiveness of protection against overheating.It has 80 PLUS Standard and LAMBDA S ++ certificates, received an active PFC corrector and a large list of protection functions. The manufacturer measures a three-year warranty, and in general, the model has been on the market since 2019 and so far has not received critical complaints.

As for user reviews, buyers attribute the quality of circuitry, soft wires, and excellent value for money to the advantages of this PSU. At the same time, in some cases, characteristic squeaks were noted in the first days of operation, which disappeared with time. Also worth mentioning is the rather loud operation of the cooling system, especially at loads above 300 watts.

An inexpensive model from Q-Dion, a sub-brand owned by the notorious FSP Group, which indicates a good quality power supply. Appearance is as modest as possible - gray metal, non-removable wires without braid - everything corresponds to the price tag. It is unlikely that it will be possible to assemble a beautiful PC based on it. Note that there are two versions of this PSU: in one (letter A at the end of the marking) there is no shutdown button and no PFS, which we will write down as minuses, and in the one that got into the rating everything is in place. Pleased with a slightly longer cable length than competitors.

Independent tests have shown that the Q-Dion QD450 has an excellent efficiency rate: even under maximum load, the power supply provides an efficiency of at least 80%. Also, experts note an acceptable temperature level, but adjusted for the cost of the device. Among the obvious shortcomings, only inhigh noise level at loads over 150 watts.

This South Korean power supply entered the market in 2020 and has already gained some popularity. Wattbit II ZM600-XEII features are enough to build a productive working system and even build a budget gaming PC. Yes, the model did not receive cool options and 80 PLUS certification, but it can offer everything you need for an inexpensive computer: a separate 8-pin for CPU power, a wide range of protection options, enough power, two video card power cables and a protective sheath of wires.

Customer reviews say that the model meets the declared characteristics, and also makes noise at an acceptable level, and this despite the active cooling system without fan speed control. At the same time, many believe that the cost of this PSU is somewhat overstated due to minor flaws: basically, these are nitpicking about the quality of the cable winding and their quantity.

A very interesting option for reasonable money. The key feature is the quiet operation of the cooling system even under load, although in rare cases there are instances with a “crooked” fan prone to whistling. Experts also note a good study of circuitry, which contributes to efficient cooling, plus guarantees the stability of performance.There is also a rich selection of cables, among which there was even a place for one 4-pin Floppy.

This power supply does not receive any particular complaints in the reviews, which makes it an excellent choice for building inexpensive gaming PCs with a video card that has modest power requirements. At maximum loads, it can start to make noise, plus it overheats during power surges in the network, so it is recommended to connect it through a reliable stabilizer. And, of course, the price, which many consider overpriced by about 1000 rubles.

By the numbers - a very powerful power supply. The manufacturer claims 700 W, but the measurements show less data - the efficiency leaves much to be desired. At the same time, the cost of the device is one of the lowest in the class. Paradox. What about other aspects? Appearance is quite interesting - vyshtampovki and beveled corners give some zest - the device will look great in a gaming computer. The cables are multi-colored, most of them without braid - minus for them. And the length allows you to install the PSU only in MicroATX cases. We also scold the set of connectors - they are enough for a 500-horsepower unit, but not for a 700W model.

Dignity

• Power 700 W.

Flaws:

• Low efficiency - at a load of more than 600W, the value drops to 76-78%;
• High noise level - up to 54 dB at maximum load;
• High Temperatures - Capacitors can reach temperatures of up to 65 degrees.

It is worth noting that the stated shortcomings will not interfere with everyday work due to the impossibility of achieving maximum power in most situations.

A very powerful and reliable power supply, but at the same time quite inexpensive by the standards of the mid-price segment. Suitable for assembling a gaming computer, as it has a high efficiency, which confirms the presence of a certificate of 80 PLUS Gold. In 2020, the model was updated with Japanese capacitors, after which the manufacturer's warranty increased from 5 to 10 years, i.e. Deepcool has no doubts about the reliability of its products.

Of course, there are also disadvantages. Many people would like to increase the number of SATA cables by a couple of three, be able to unfasten extra wires and reduce fan noise due to the speed control option. We also note that this model is not equipped with braided cables, and this at least worsens the appearance of the PC system unit. In general, we have a good PSU with an excellent balance of price, reliability and functionality offered.

FSP group fully follows its "beliefs" - to create inexpensive and simple outwardly power supplies with powerful and high-quality stuffing. The case is practically no different from models half the price, and therefore aesthetes who want to assemble a beautiful computer will not like the model. Also you won't find any mention of having 80plus certifications. The unit shows a smooth efficiency (83-85%) over the entire power range. But there is a caveat - with a power of over 500 watts, it is likely that the PSU will simply turn off. But voltage stabilization works fine: on the 3.3 and 5 V lines, the deviations are no more than 0.02 V, on 12V - no more than 0.5 V.

The cooling system did not deserve such praise - the temperature of the components is quite low, but the rotational speed of a 120 mm fan changes in a very small range, and therefore the noise level is almost always above average - 45-46 dB. The advantages are called high power for little money and excellent voltage stabilization. The disadvantages are a high noise level and the fact that the model can turn off at a load of more than 500 watts.

One of the best selling power supplies in the last couple of years. On the market since 2018, it offers a three-year warranty, 80 PLUS Bronze compliance, good electrical specifications, separate cables for CPU and GPU power, plus active power correction and an extended list of options for protection against overloads and overheating. Having paid a little more than 1000 rubles, you can take the version with detachable cables, however, you can remove only part of the extra wires.

Reviews are full of praise for the use of high-quality capacitors and controllers, excellent elaboration of the cooling circuit and a rich set of cables. Almost no one names the noisy model either, but the presence of a starting howl is noted, i.e. short-term activation of the fan at full speed. Among other minor shortcomings, we highlight complaints about the uncomfortable braiding of wires.

Elite in all respects power supply. After unpacking, the reinforced protection of the 135 mm cooler, made in the form of a powerful grid, immediately rushes. Since the product is completely modular, several weighty “braids” of cables are waiting for you in the package, pulled together for ease of transportation. The bolts are by default, as are the additional cable ties. The manufacturer "finishes" the buyer with a 5-year warranty, which, coupled with increased reliability, fully justifies the price tag of the device.

It has only two minuses and both are insignificant. The first lies in the lack of LED backlighting (although who needs it on a PSU?), and the second is in availability, since the goods are supplied in small quantities and are quickly sold out.

Insanely expensive and high-quality product from Sea Sonic. The power is only 650 W, but almost all the energy is used, only a small part of it goes into heat. The design is cool on one side and minimalistic on the other. The circuitry is made at the highest level, all components are located at a sufficient distance from each other, which eliminates mutual heating. Cable loops are flat and this is a big plus, as you can minimize the volume occupied by wires and “unload” the internal space of the PC by removing all unnecessary into the case.

What's really amazing here is the guarantee. It can vary from 10 to 12 years. On it you can overclock any top-end system without drawdowns, and there will be enough power in reserve due to the strong 12 Volt line. The semi-passive cooling mode starts the fan at 50% load, the rest of the time regular radiators work.For such a price, there should be no flaws, but in rare cases, chokes start to squeak, but the company can easily replace such a PSU under warranty.

This power supply is ideal for buyers who do not let go of the thought about the lack of power of the PSU and its reserve for the future. The kilowatt unit is based on Taiwanese capacitors, which are slightly inferior in quality to Japanese ones. It works silently at low loads, but at maximum performance it starts to make noise. However, in order to fully load such a powerful model, you need to assemble the best and most powerful components in the world.

The design is completely modular. The wires bend easily, even despite a solid braid. This will allow you to fully engage in cable management. Another of the amenities, we note a sticker above the ports, indicating where and under what the seat is located. According to reviews, the wires are attached tightly without backlash. The bronze certificate indicates 83-85% energy efficiency.

Finding fault with anything in this power supply is difficult. Judging by the measurements, the efficiency is fully consistent with the 80 Plus Gold certificate. Also there are all necessary protection systems: from overvoltage, from overload, from short circuit. But all this is usual for this category. But a fully modular system with flat and very flexible cables cannot but rejoice. Due to their sufficient length and high flexibility, they can be easily hidden in special niches.The bundle also pleased - a cloth bag, detailed instructions, a full set of cables and a dozen plastic ties for fastening.

Advantages:

• High efficiency and availability of all necessary protection systems;
• The best current strength on all lines;
• Fully modular design with soft wires;
• Using Japanese capacitors and 5 years warranty;
• Low noise level.

An expensive, but extremely reliable power supply with detachable cables and a semi-passive cooling system, i.e. The fan speed is adjusted according to the applied power and the temperature of the condensers. This ensures the maximum level of silence of the cooling system, although a quiet hum is possible under high load. The model also offers an expanded number of cables of all types, compliance with the 80 PLUS Gold standard and a 10-year warranty from the manufacturer.

Reviews on the PSU are mostly positive. Buyers note the noiselessness of CO, especially with low power consumption, the quality of the used components and convenient connectors that do not get stuck when connected. Of the minuses, complaints about the high price, the possible smell of plastic after launching out of the box, and the excessive rigidity of the cables at the base of the connectors most often pop up.
