10 best power supplies

All things around us consist of individual parts. Accordingly, a device or object can be disassembled into its component parts. But let's think that an ordinary person can buy in parts, then to collect something whole? A smartphone or audio system is unlikely, but enthusiasts collect personal computers very often. The result is a little cheaper than the finished factory assembly. And the pleasure of the process has not been canceled.

Of course, the motherboard, a powerful processor and a video card, a large amount of RAM are important, but without adequate power even from the coolest components there will be no sense. And the elements are provided with energy by a small box, to which sometimes they pay very little attention - this is the power unit. We will try to correct such a serious omission in our traditional rating. But before moving on to it, let's consider a couple of very important points.

Top Power Supply Manufacturers

In recent years, the market of stationary PCs and their component parts has been losing momentum gradually, however, there are no fewer manufacturers. It should not be forgotten that some smarter companies simply stick their logo on the finished product. Trust this, of course, not worth it. Fortunately, the scope of BP is quite conservative and there are a number of companies that can be trusted without any doubt - these are Antec, be quiet !, ENERMAX and SeaSonic. Also noteworthy are the major players in the component market, such as Corsair, FSP, ZALMAN, DeepCool, AeroCool, Chieftec, etc., which produce slightly cheaper options.

The best inexpensive power supplies worth up to 2 500 rubles.

3 GIGABYTE GZ-EBS50N-C3 500W

At first glance, BP from GIGABYTE inspires confidence. Solid black matte body, the hole for the wires is limited to a plastic ringlet that prevents chafing. Wires, of course, without braiding, but in this price category you can not expect another. You can also praise the power supply unit for the thin wire grille covering the cooler - blowing through this is great, and getting to the fan for cleaning is easy. Everything is fine, but there is one huge snag - in fact, the PSU produces a maximum of 350 watts, which is indicated not only by the small text on the sticker, but also by real measurements.

Advantages:

• Good design
• Convenient access to the fan for cleaning
• Lowest cost

Disadvantages:

• Actual power does not match declared

2 FSP Group Q-Dion QD450

The second line of the ranking is an inexpensive model from Q-Dion. In fact, the model was developed by the well-known FSP Group, which indicates a good quality of the power supply. The exterior is the most modest - gray metal, fixed wires without braid - everything corresponds to the price tag. Collect on its basis a beautiful PC is unlikely to succeed. We note that there are two versions of this power supply unit: one has no shutdown button, which we will write to the minuses, the other has it. Pleases a little more cable length than the competition. Independent tests revealed the following:

Advantages:

• Excellent indicator of efficiency.Even under maximum load, the power supply provides an efficiency of at least 80%
• Acceptable Temperature Level

Disadvantages:

• High noise level with load over 150 W

1 AeroCool VX500 500W

AeroCool is an excellent manufacturer of cooling systems, but they also have a very good power supply unit. Power, according to users, is as stated, the build quality is good, but there are several serious flaws. Firstly, a high level of noise, which cannot be overcome without serious interference in the inside. Secondly, there is only a 6-pin connector for a video card. Fortunately, the cost of the model is the lowest in our rating, and therefore, if silence is not important to you, you can safely buy.

Advantages:

• Relatively high efficiency
• Good appearance
• Large area of ​​air vents
• Gives up to 38A on 12V1

Disadvantages:

• Noisy
• No 6 + 2 pin connector

The best power supplies cost from 2500 to 5000 rubles

4 Chieftec GPE-700S

Opens rating very powerful power supply. The manufacturer claims 700W, but measurements show smaller numbers - efficiency leaves much to be desired. The cost of the device is one of the lowest in the class. Paradox.

What with the rest of the aspects? The appearance is quite interesting - stamps and beveled corners give some zest - the device will look great in a gaming computer. The cables are multicolored, most without braid - for them a minus. Yes, and the length allows you to install the PSU only in MicroATX enclosures. We will also argue a set of connectors - they are enough for a 500-strong unit, but not for a 700W model.

Advantages:

• Power 700 W

Disadvantages:

• Low efficiency - on load over 600W, the value drops to 76-78%
• High noise level - up to 54 dB at maximum load
• High temperatures - capacitors can heat up to 65 degrees

It should be noted that the stated shortcomings will not interfere in daily work due to the impossibility of achieving maximum power in most situations.

3 Deepcool DQ550ST 550W

The third line of the rating is not the easiest power supply. It has the lowest power among its competitors at the highest cost. But investments are more than justified. The reason is in compliance with the 80plus Gold certificate. The exterior corresponds to the price tag - the steel case is painted black, and behind the removable grille there is a beautiful white fan 120 mm in diameter. Cable without braid, black, flat - it is convenient to hide such cables to create maximum “clean” look inside the PC. A set of cables is enough to build a modern gaming or office system.

Advantages:

• Efficiency of at least 87.5% over the entire power range. With a load of 250-350 W, the indicator rises to 90.1%. Best in class
• Low noise - 35.5 dB under load
• Stable voltage

2 FSP Group ATX-600PNR

FSP group fully follows its "convictions" - to create the most inexpensive and simple externally power supplies with powerful and high-quality stuffing. The case is practically no different from the models twice cheaper, and therefore aesthetes who want to assemble a beautiful computer, we recommend immediately to pay attention to another model. Also, you will not find any mention of the availability of 80plus certificates. The model shows smooth efficiency (83-85%) over the entire power range. But there is a nuance - with a power over 500 W there is a chance that the power supply will simply shut down. But voltage stabilization works fine: on the 3.3 and 5 V lines, the deviations are no more than 0.02 V, at 12V - no more than 0.5V.

The cooling system does not deserve such praise - the temperature of the components is quite low, but the rotational speed of the 120 mm fan varies in a very small range, and therefore the noise level is almost always above average - 45-46 dB

Advantages:

• High power for little money
• Excellent voltage stabilization

Disadvantages:

• High noise level
• Can be turned off when the load is over 500 W

1 AeroCool KCAS-650M

The leader is the power supply from Aerocool. Line KCAS refers to the game. The design of the device unambiguously hints at this - the strict features of the case and the non-distinguishing fan behind the stylish grill are combined with a juicy sticker on the side wall. The fan has a diameter of 140mm, which allows it to spin with a relatively small frequency, and therefore the noise level remains at an acceptable level, which is confirmed by numerous reviews. The unit belongs to the class of partially modular: only 24-pin ATX and 8-pin CPU cable come out of the case, everything else is unfastened if necessary. All cables come in protective sheath. The cables themselves are multicolored - just a minus to the aesthetics of the computer.

When testing, there are no obvious minuses. The manufacturer claims compliance with the 80plus Bronze standard. The minimum efficiency is revealed at the power of 150 and 550 W - 85-86%. In all other modes, the indicator did not fall below 90%. Fine!

Advantages:

• High efficiency
• Low noise level - 35 dB in normal mode
• "Smooth" voltage on all lines.

The best power supplies are more expensive than 5000 rubles

3 GIGABYTE G750H

The category of top-end power supplies will start with a relatively inexpensive 750 watt model. The G750H has a very simple design - a black faceted case, an inconspicuous 140mm fan behind a removable grill. The only thing that dilutes the picture a little is the bright stickers on the side faces. The design is partially modular, the main cables are built into the case, the rest can be disconnected if necessary. I am glad that all the wires are made in one color - black - this adds to the integrity of the assembly. Still a fabric braid ...

Power supply unit corresponds to the nominal. Efficiency in the entire power range at an excellent level - 88-92%. Also pleased with the voltage stabilization system. With an increase in the load of 12V, the line does not deviate from the nominal by more than 0.1 V. The rotation speed of the fan in almost all modes is 800 rpm, which creates noise at 40 dB.

Advantages:

• Rated power corresponds to real
• Excellent voltage stabilization
• High efficiency

Disadvantages:

• Somewhat noisy

2 Cooler Master V650 Modular 650W (RS650-AFBAG1)

To find 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 the necessary protection systems: overvoltage, overload, short circuit. But all this is customary for this category. But a fully modular system with flat and very flexible cables can not but rejoice. Due to sufficient length and high flexibility, they can be easily hidden in special niches. The package bundle also pleased me - 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 on all lines
• Fully modular design with soft wires
• Using Japanese capacitors and 5 years warranty
• Low noise

1 Thermaltake Toughpower DPS G RGB 650W

Thermaltake know that gamers need power and beauty. Both requirements are satisfied by the leader of our rating. The efficiency indicator is simply excellent - it decreases below 90% only with a load of 1/10 of the maximum, while in all other cases it is at the level of 91-93%. At the same time, it is impossible to call the system noisy - with a load of up to 60%, the fan speed is lower than 600 rpm, making it almost impossible to hear it in the case.

By a little less useful, but no less interesting features include RGB backlight and proprietary software. Programs are for PC and for smartphones on Android and iOS. It is better not to even remember the last ones, because the quality of execution is just awful, but the desktop application is quite efficient and useful. With it, you can change the color and brightness of the backlight, see the temperature of the PSU, amperage and voltage in selected sections, efficiency and power. It is also possible to set the cost of 1 kWh in dollars and see in real time how much money your PC spends.

Advantages:

• High efficiency
• 4 PCI-E 6 + 2-PIN, 8x 4-IDE and 8 SATA PIN
• There are RGB lights
• Useful PC application
• Very nice and full set
