Best Power Supplies for Gaming PCs - Top 550W and Above PSU in 2022

What is the best gaming power supply? Has the time come for you to replace your PC's PSU because it is not powerful enough to handle both your new processor and graphics card or you are just building a new gaming PC, HEDT, server or even a home-made NAS? We have looked into these questions, and let us tell you that choosing a good PSU is not always easy and we think that we all need to learn learn a little more about this component that is too often neglected.

When looking for a power supply for your gaming PC, it is important to consider a few factors. One of the most important is the certification level that the power supply has. Another important factor is energy efficiency. You want to find a power supply that will not only run your PC, but also do so efficiently.

Another thing you may want to consider when choosing a power supply for your gaming PC is the modularity of the PSU. This refers to the number of cables that are permanently attached to the power supply and the number of cables that are modular, or removable.

Finally, you should also consider the price-to-performance ratio when choosing a power supply for your gaming PC. You don't want to break the bank, but you also want a PSU that will allow your PC to run at its best.

We'll go over the different levels of certification for power supplies, the importance of energy efficiency, and the modularity of power supplies. We'll also give you a few recommendations for power supplies that fit these criteria. So let's begin shall we?

What are the best 550W and Abobe PSUs in 2022?

We begin our selection with two entry-level models which, in our opinion, manage to win the prize for value for money while remaining on an entry-level budget. You will always be able to find cheaper, but this will not be without serious compromises.

1. Seasonic S12III-550

Seasonic S12III-550: a winning recipe

We are not going to lie to each other: it is much more difficult to choose a good PSU where you are on a tight budget. Competition is fierce in the entry-level segment and it is not always clear whether the quality is there. Fortunately, some manufacturers stand out and Seasonic's name comes up frequently in discussions thanks to the excellence of its various product lines.

For a first price, this power supply has a single 12 V rail (45.5 A) delivering a power of 546 W, meeting almost everything that we are able to expect for our machines. Thanks to the great care taken during the choice of components and then the assembly, Seasonic delivers here an S12III series, available in 4 versions (450/500/550/650 W), which does not lack arguments to its advantage.

As usual, the Taiwanese company offers us a reliable product that meets many standards and includes the protections (OPP, OVP, UVP, SCP) necessary for use with complete confidence. The sound level is also one of the manufacturer's priorities in this range. As we saw with the CORE GM-500, here we find the S2FC technology which allows efficient and silent cooling. The sound level of the 120 mm fan certainly increases significantly at full load, but remains discreet in all circumstances.

On this price range, we remain here in the presence of a non-modular power supply whose efficiency does not exceed 85% with the 80 PLUS Bronze certification. Seasonic, however, offers black and flat cables, which should make up for the lack of modularity.

The connectors are rather well supplied since in addition to the usual connectors (ATX 20 + 4 pins and CPU 4 + 4 pins), there are 2 PCIe connectors, 6 SATA plugs, 3 Molex and a Floppy. The cables have an ideal length: between 45 cm and 60 cm for the longest of them (P8).

2. Cooler Master MWE 550 V2

To introduce this product and begin to go into the details, let's first note that we are dealing here with a V2 model from the MWE series. Thus, it is advisable to pay attention during your purchase and make sure that it is indeed the V2 and not the first MWE series.

The differences between these two versions are barely perceptible at first glance: the two PSUs have the same name and benefit from a similar design. However, this V2 offers a much more modern operation with its DC-DC + LLC topology; without going into technical details, know that this is an important upgrade since it allows the voltages to be regulated independently for each rail.

Apart from this essential upgrade for our current configurations, the MWE V2 (available in 450/550/650/750 W version), Cooler Master has integrated a 120 mm HDB fan whose particularity is to be equipped with a hydro-dynamic mechanism, thus extending its life and keeping the sound level to a minimum. At low loads (less than 15%), the fan stops spinning again contributing to its longevity and efficiency. If the power supply is silent below this load, it remains quite discreet on higher loads with 11.13 dB at 20%, 15.6 dB at 50%, 31 dB at full load.

With an 80 PLUS Bronze certified performance, the MWE 550 V2 should be sufficient for many gaming configurations thanks to its 12 V monorail delivering 45.8 A (549.6 W), its 2 PCIe connectors, or its 6 SATA plugs.

3. Seasonic FOCUS GX-650

We go up slightly in power and in range with power supplies which display here better energy efficiency and a modular design which makes it possible to eliminate unnecessary cables.

To begin with, there is a second model signed by Seasonic the Focus GX-650, a PSU that does not fail to take up the criteria of requirements and the high standards of the manufacturer.

Seasonic FOCUS GX-650: Taiwanese excellence

With this new model in the GX series (from 550 to 850 W), Seasonic cuts a fine figure with a choice of premium components and serious assembly and manufacturing.

If we already notice the quality of Seasonic's work just by observing the redesigned and improved chassis compared to the previous range and with a very good level of finish, it is above all its internal design that we can qualify as innovative. Among the novelties, the internal design devoid of cable is certainly one of the points to highlight. Here, the PCB and the rear panel are connected together thanks to a copper plate which replaces the cables. This results in increased stability for the output voltages, but it also represents an advance in the manufacturing process, which is simplified thanks to this method.

100% modular and displaying a very good level of efficiency (80 PLUS Gold), the Focus GX-650 has only one 12 V 54 A rail, so many arguments that predestine this model to equip greedy machines in energy and overclocked systems.

Equipped with perfectly flat and easy-to-install cables, the GX-650 is delivered, among other things, with its 24-pin ATX cable, two 4 + 4-pin connectors, 4 PCIe connectors, or even 12 SATA connectors; enough to provide you with more than you need.

Finally, Seasonic has also put a lot of effort into cooling with a 120 mm fan that benefits from high-performance hydrodynamic bearings, known to generate less noise and heat pollution than conventional ball bearings. In addition, there is also a fan control command, located next to the power switch, it allows you to switch to hybrid mode, a mode in which the ventilation adapts according to the load of the power supply (Fanless mode, Silent and Cooling).

4. be quiet! Pure Power 11 700W

The be quiet! brand is very often mentioned when it comes to choosing an excellent power supply! And for good reason, the manufacturer of PC cases and cooling solutions offers PSUs that are intended to be relatively quiet and have reasonable prices. One of the best value for money in the PSU mid-range sector.

be quiet! Pure Power 11,700W: solid and efficient

For once, we are in the presence of a multirail power supply, it has two 12 V rails with fairly large amperages (30 and 36 A) for a combined total power of 672 W. In fact and despite the presence of these two independent rails, the Pure Power 11 700W is capable of powering relatively power-hungry components, it will simply be necessary to distribute the load according to the manufacturer's specifications.

The first rail is thus intended to supply the SATA plugs, the 2 PCIe connectors and the ATX 24 pins. The second rail provides the necessary energy for the CPU (P4 + 4) as well as for two additional PCIe slots.

As for the components chosen, we remain on quality hardware even if be quiet! made the choice not to opt for Japanese capacitors. Finally, the German company has focused more on the question of the balance between price and performance. We thus find all the necessary protections, but also relevant technologies guaranteeing voltage stability that could not be more reliable (DC-DC, Active Clamp, Synchronous Rectifier).

Finally, discretion is obviously required with silent operation up to 60% load. At full load, the noise level does not exceed 25.9 dB, which is quite satisfactory for a 700 W power supply. To top it off, we have to deal with a PSU that displays excellent performance since it is certified 80 PLUS Gold (up to 92% return). Note also that it does not consume more than 0.17 W when the system is on standby.

5. Corsair RM750x v2

Corsair's RMx series got a very interesting upgrade with its second generation. On the program: slightly more compact models, guaranteed for 10 years and fully modular, but which are above all among the quietest on the market.

Corsair RM750x v2: one of the quietest on the market

Intended to equip high-end configurations with its 750 W power, the RM750x v2 proves to be a relevant revision of the original model. At first glance, few changes are noticeable, but the improvements are definitely present, starting with the size of the block, which goes from 20 to 16 cm in length. If it is not the most compact model on the market, it is however a very good point which allows greater compatibility with smaller boxes.

For this upgrade, Corsair has also opted for a cable-free internal design, which significantly improves airflow within the PSU. We finally realize that the challenge taken up by the manufacturer was quite thorny, because a gain in compactness generally generates additional noise pollution. Only Corsair does very well here with a noise level that does not exceed 15 dB with a 70% load and less than 21 dB at full load, which earned it the LAMBDA A+ certification. This quality of the RM750x v2 is given by its new internal design, but also to its 135mm fan and its semi-passive operation. It only activates beyond a 40% charge and continues its efforts after 70% charge. The only point of disappointment is certainly the absence of a command to activate and deactivate the semi-passive mode, as can be seen on the Seasonic FOCUS GX-650.

To end briefly, note that Corsair keeps its promises here. The amperage allocated to the single 12 V rail is indeed 62.5 A, which indicates an output power of 750 W and no less. Finally, the connection is very well supplied with in particular 4 PCIe connectors, 9 SATA plugs and 8 Molex (4 pins).

6. Antec HCG850 EXTREME EC

No 80 PLUS Platinum or Titanium certified model to close our selection. The price difference is still far too great compared to a Gold certification, we prefer to offer you a model that maintains a contained price while offering excellent performance.

Antec HCG850 EXTREME EC: Editor's Choice

Antec was right on its high-end offer with its power supplies with the extended name High Current Gamer Extreme Series. Available in a 850 or 1000 W version, this range is based on the platform of one of the leaders in the sector, which is none other than Seasonic. Antec has indeed partnered with the Taiwanese manufacturer to develop these two blocks, they are thus based on a platform similar to the Focus Plus range from Seasonic.

It is clear that this is very good news that guarantees quality in all respects irreproachable, which is not always the case on the less expensive models that Antec puts on the market, often coming from OEM much less deemed as Seasonic. The major advantages of this HCG850 lie in this fact: the quality of assembly is there, in particular with perfectly made welds, and components clearly above the lot as evidenced by the various Japanese capacitors.

Antec has also been able to take advantage of its expertise, we notice it first of all with the design of this power supply and its golden colors which break with the usual and rather austere aesthetics of most models. The Californian company has also focused on reducing noise pollution. We thus find a neat internal design and thought to maximize the flow of air.

It is easily noticed in use for the simple reason that the 135 mm fan and its wide blades activate quite late in load, a sign that the heat dissipation of the block is particularly effective. Absolutely silent up to a certain threshold, this fan therefore offers a very appreciable “Zero RPM” hybrid operation. At maximum speed (2300 RPM) remains discreet; in other words, you really have to listen carefully to notice it.

As for the technologies present, we are once again close to perfection. For example, we can cite the very complete suite of protections called CircuitShield, or the PhaseWave design (LLC, Synchronous Rectifier, DC-DC converter) which guarantees efficiency and voltage stability. Finally, note that this is a relatively powerful monorail block: it offers 70 A on its 12 V rail, which represents a power of 840 W. In terms of connections, we are rather well served with 2 connectors EPS12V (4 + 4), no less than 6 PCIe connectors, 10 SATA plugs, 6 Molex and 1 FDD, the whole thing is obviously entirely modular. The only negative point for some will be the nature of the cables, Antec has preferred here sheathed cables which are therefore slightly bulkier than flat type cables.

How to choose a good power supply for your gaming PC?

Tips for choosing your power supply

When we choose to mount a new gaming configuration, we generally analyze with great care which processor, graphics card or RAM will integrate our box. On the other hand, we often give less importance to the choice of the power supply unit, or PSU (Power Supply Unit) in the language of engineers, by simply ensuring that the power delivered corresponds to the needs of your gaming PC configuration.

However, the power supply of a PC is essential for the stability and electrical safety of all the components of your machine and, we would like to emphasize this from the outset, it should not be subject to compromise. In other words: do not try to save on the purchase of your food; If possible, opt for models known for their quality, energy efficiency and durability!

To make your choice with peace of mind, we have selected 6 models recognized for their quality, both entry-level and top-of-the-range. In addition, the few tips below can help you narrow your search.

A matter of power, but not only!

More or less energy-intensive depending on various parameters, the components of your PC as well as your peripherals draw their energy from a single source: the PSU of your machine.

Logically, the first question that comes to mind is none other than that of the power required to properly power your machine, something that we will address without further delay in the following paragraph. However, we will see that power is not the only criterion for purchasing a PC power supply, far from it. Energy efficiency, modularity, voltage stability, noise pollution and other safety standards are all parameters to integrate into the equation.

Define the consumption of your PC

First of all, it must be understood that we are talking about maximum power consumption a PC might require and that in fact, your desktop will rarely require this value to operate for the simple reason that your components are not all solicited at 100% constantly and simultaneously.

Nevertheless, it is necessary to choose a power supply that covers and exceeds (by around 20% minimum) the maximum requirements of your configuration. Care must be taken to ensure that your power supply is not continuously used at full load, as its potential lifespan and its efficiency could then be strained and reduced.

It is therefore important to choose a power supply slightly more powerful than the overall maximum power consumption of your PC. You can widen the gap a little more in case, in the near future, you plan to add or change some components of your PC.

For example: if you change your GPU for a more efficient model, if you are considering an SLI/Crossfire configuration with several NVIDIA or AMD GPUs, or even the subsequent installation of water cooling, it will be necessary to equip yourself with a more powerful power supply right now because you won’t have to worry about having to change it when the time comes.

Finally, if it seems very logical not to choose a power supply that is way too powerful, a power supply that is too powerful will simply be useless to you if the subsequent need is absent. The more powerful the power supply and higher its price will be, and investing in a PSU that will be under-exploited will do you no good in terms of efficiency since usually a power supply’s best efficiency zone is located between 60 and 80% of its operating power.

Gaming PSUs: Cables and modularity

Connectors and cable lengths:

As a general rule, it is not particularly necessary to worry about the connectors of the power supply, most PSUs are complete and versatile and have everything necessary to connect your components to them. However, you can check the presence of a 24-pin (or 20 + 4) ATX connector for your motherboard, 6 + 2-pin PCI-Express connectors for the graphics card(s), an ATX P4 connector (4 or 8 pin, sometimes declined in 2 x 4 pin), and finally SATA and Molex power cables for all your hard drives and SSDs, as well as for your cooling system or RGB lighting.

Finally, certain criteria such as the length and flexibility of the cables can be important for some. Some boxes are indeed less well optimized than others with regard to cable management, we will appreciate in this case to take advantage of relatively flexible cable to facilitate the task.

Finally, manufacturers often offer, in the case of modular power supply, sheathed and colored cables. They are obviously not essential, but offer several advantages: that of benefiting from an aesthetic in line with the other elements of your configuration (for those who have a box with a view on its entrails), of optimizing cable management and therefore the circulation of the air flow in the box, or even as a visual cue to quickly identify which cable supplies what, which facilitates the maintenance of your machine.

PSU Modularity

  1. Non-modular power supplies are recommended for light office configurations, where the main requirement will be to contain the bill. The cables of such a power supply are fixed, so you will probably end up with unused cables that you will have to "stash" somewhere so that they don't lie around in your case.

  2. Semi-modular power supplies give us the benefit of some removable cables, good news since we can then remove the cables that are not necessary for us, such as certain SATA and Molex cables, or one or more PCIe cables. The price of a modular power supply is a little higher, but it allows you to benefit from better cable management.

  3. Modular power supplies: it is necessary to make the difference between modular and semi-modular, which is not always easy because the shops often speak of modular power supply for semi-modular models, while they use the term full modular to designate power supplies where absolutely all the cables are removable. Modular power supplies have a much higher price for some advantages that will not be useful to most of us since here, even the 24-pin ATX connector is removable, whereas it is essential. The interest here is therefore to be able to customize our configuration as much as possible, in particular by opting for colored cables.

Energy efficiency and certifications

The energy efficiency of a power supply is one of the first points to scrutinize carefully. It is neither more nor less than its capacity to convert the energy of the network into direct current (230 V here in Europe) according to the operating voltages of your machine.

The lower this efficiency, the less efficient the power supply is in converting the current. This results in heat loss with high heat dissipation, but also in excess power consumption compared to what your machine consumes, which can end up being felt on your bills, especially if you use your PC for several hours a day. day.

Fortunately there is a certification that allows us to know the energy efficiency of a PSU, and therefore the quality of its materials and its assembly. This certification, as you might have guessed is the 80 PLUS standard and we are sure that you have most certainly already encountered it. As its name suggests, this label signifies that the power supplies in question all have a minimum efficiency greater than 80%.

You should know that the performance is different depending on the use of the power supply. The optimal value is at 50% workload, it is slightly reduced with a load of only 20%, but also with intensive use at 100% load.

Before giving the details of each label, we would like to advise you to never to choose a power supply that does not display at least the first level of this 80 PLUS label. The heat generated will be far too high and the goal is obviously not to add more heat to your configuration, but rather to keep it cool.

Ideally, we recommend going with at least an 80 PLUS Gold power supply, for the simple reason that the price difference is not noticeable between Bronze, Silver and Gold. On the other hand, prices jump as soon as you look for a certified Platinum or Titanium power supply.

The 6 levels of 80 PLUS certifications of the Ecova label:

  1. 80 PLUS: yield between 80 and 82%

  2. 80 PLUS Bronze: yield between 83 and 85%

  3. 80 PLUS Silver: yield between 85 and 88%

  4. 80 PLUS Gold: yield between 88 and 92%

  5. 80 PLUS Platinum: yield between 92 and 94%

  6. 80 PLUS Titanium: yield above 95%

Conclusions

To conclude, we advise you to pay particular attention to the certification of the power supply (80 PLUS) and, if possible, to choose a model that is certified Platinum or Titanium. The price difference with Gold models is not very important, while the gain in performance and heat dissipation is considerable. Finally, it should be noted that a semi-modular power supply is not a bad choice, provided that you do not need all the cables that it offers. In this case, it is always better to opt for a modular model.

We hope that this article has helped you better understand the different types of power supplies and their respective performances. If you have any questions, do not hesitate to ask us in the comments!
