  • Expensive

Corsair RM750X

Staff Pick
Best PSU for AMD

In the world of power supplies, Corsair is a household name. In order to supply reliable power to high-end computers, the RM series has been created by Corsair for systems that need a high-quality power supply without sacrificing efficiency or generating excessive heat. Its modular cabling design permits easy installation and removal of unused connectors.

There is a 5-year warranty on the RM750x, and it is 80+ Gold certified for consuming less power, being quieter, and running cooler. Efficiency under high loads is the only area that can be improved, and that is why the average efficiency is not so competitive. This white PSU is a good choice if you are looking for the best PSU for AMD Ryzen 5900X for under 150$.

As the competition in this market has grown more intense, it is time for Corsair to update its popular RMx line of power supplies. Indeed the task’s tough since the prevailing RMx units only counted three years in production and delivered excellent performance alongside dead silent operation but RM750x remains a winner in the 750W category if corsair maintains its price under $133.

Pros

  • Excellent voltage regulation.
  • Fully modular 2x EPS & 4x PCIe connectors
  • Full power at 49 °C, Efficient, Silent, Low ripple, Load regulation on the minor rails Quality caps, Holdup time.

Cons

  • Again, CWT’s infamous solder bug strikes, but this time only on the VRM board.
  • Fan-test button not available.

XPG Core Reactor 650W

Budget Pick
Budget PSU for AMD Ryzen 5900X

XPG rocked the boat with its Core Reactor line, an emotional set of PSUs using a competent platform handed by Channel Well Technology. XPG took over the CSE platform of the company and secured exclusive rights to it, so you won’t see another OEM using CSE. So far, there are only a few PSU brands that own exclusive rights to OEM platforms, such as Corsair, and be quiet, so with this move, it is confirmed that XPG is serious about becoming the best power supply company in the world.

The XPG Core Reactor with 650W had to face competition against many renowned power supply units of the market. It is emotional that still, it manages to win the race. In the light of facts historically XPG hasn`t been such a power in the market, it has hired some professional people for this job. Compact footmark is also a significant feature of this PSU; it makes the installation process more easily manageable.

The completely modular lines will also help in this too. Speaking of the lines, they do not have in-line capacitors, making string lodging harder than it has to be. The only real debit in this unit is the brace of EPS connectors hosted on the same string. It is generally recommended to install EPS connectors on dedicated lines to reduce voltage drops and enhance safety, but there aren’t enough sockets for this on the platform. The price of this power supply made it eligible for our Best budget power supply for AMD Ryzen 5900X category.

Pros

  • 10-Year Warranty.
  • Full power at 47 degrees Celsius.
  • Fully modular.

Cons

  • Two EPS connectors on the same cable.
  • The heat-dissipating addict should be in the center.
  • The price is slightly on the advanced side.

Fractal Design Ion SFX 650W Gold

Best PSU for Gaming

Silverstone was the first brand that took some serious interest in SFF PSUs, which has the richest affiliated products portfolio. In the meantime, until Fractal launched these SFX Gold units, it had nothing to show for this order.

Nevertheless, the term SFX is inaccurate since both Fractal Ion units are based on Silverstone’s unofficial SFX-L form factor. Because of the larger than SFX depth — by 30 mm — SFX-L units allow for larger cooling suckers and better tailwind. That means they can have further relaxed addict speed biographies and be quieter than their standard SFX counterparts. On top of that, the larger PCBs allow for advanced capacity units, too, up to 1000W. The Ion SFX 650G is an excellent SFX power supply that can compete with Corsair SF600 power supplies in terms of performance and quality, which still leads the 600W SFX order with Cybernetics ETA-A and 80 PLUS Gold effectiveness instruments.

Compared to the Corsair SFX model of similar capacity, the Ion has a large fan with an aggressive speed profile. However, the ten-year bond, the largely flexible modular lines, and the ATX-to-SFX appendage type which is missing in the SF600 Gold unit’s pack. Besides Corsair’s immolation, good rivals of the Ion 650G are the EVGA 650 GM and the Seasonic Focus SGX 650W, which uses the equal stage as the Ion unit. It isn’t so frequent to see a ten-year bond in an SFX power supply. It was only Seasonic that gave it until now, but since those Fractal Design power supplies share the same platform, they are covered by the same warranty.

Pros

  • 10 years warranty.
  • Comes with SFX-to-ATX mounting bracket.
  • $10 cheaper than the cheapest equivalent wattage competitor.

Cons

  • Split ATX 24 pin at the PSU end.
  • Aggressive fan speed profile.
  • High inrush current with 230V input.

Corsair CX450

Best PSU under $100

The smallest capacity factor of Corsair’s budget-initiated CX line is the CX450. CX models are manufactured by two companies: Great Wall and Channel Well Technology, each of which has its own platform. The only way to tell them piecemeal is their RPS figures, source designators presented to each model. Both configurations have positioned lines to keep the cost as low as workable.

There is no comparison between the two Corsair CX450 models, with the one made by Great Wall being substantially more effective, specifically under light loads, and has a more effective 5VSB rail. On the other hand, it has a higher-pressure fan profile, so its noise output rises. The forenamed RPS figures help with identification. CWT manufactured Corsair CX450s with the RPS0053 stamp, whereas Great Wall made one with the RPS0063 stamp.

In the US market, you’ll only find the CWT version manufactured in Vietnam rather than China, accordingly, it avoids the tariffs and keeps its price label low. Other areas are also served by the GW platform. In general, the Corsair CX450, in either flavor, offers a high performance per price rate, and it’s an excellent preference for mainstream builds with entrenched or low-power graphics cards. In this price range, you will not ascertain such an ultramodern and suitable platform.

Pros

  • 5-year warranty.
  • Rifle bearing an.
  • Good efficiency for a low-cost PSU.

Cons

  • Non-modular.
  • Short distance between peripheral connectors.

NZXT C850

Best Power Supply for Ryzen 9 5900X

NZXT has been in business for over a decade now, and it aims to be the best manufacturer of computer components. The company offers some of the most amazing products on the market, making it a leader in the field. NZXT uses a diverse selection of materials when creating its product line, which makes them different from other computer case manufacturers.  The NZXT C850 Gold is a modular power supply unit that features an 850W output (958W peak) and an 80 Plus Gold rating for up to 90% electrical efficiency. It is also available in 650W and 750W models.

These days, all modular power supply units feature multiple power inputs, so the C850 can be used worldwide without having to flip switches.  Although automatic power input switching has been a standard feature for a while, you don’t see it every so often, so it’s worth mentioning it’s included.  The C850s silent mode is the biggest feature, in addition to its impressive TEN-year warranty.  Under low loads, it actually acts as a toggle switch, which causes the fan to run at zero RPM.  In some situations (sitting in front of the computer, doing some office work, etc), the PSU fan automatically shuts off to keep things quiet.  As soon as you start a game or start a render that consumes a lot of power, the PSU fan will involuntarily ramp up to keep it cool.

The NZXT C850 is a mid-range power supply that has been designed to satisfy both high-end gamers and PC enthusiasts, including features such as 80 Plus Gold efficiency and a single +12V rail. NZXT’s C850 PSU provides 850 watts of power at 12V while having very good voltage regulation at that voltage. Because of its high efficiency, it’s a great choice for gaming systems. No doubt that this PSU is one of the best PSU for AMD Ryzen 5900X.

Pros

  • Long hold-up time
  • Low inrush current
  • Fully modular

Cons

  • Can be noisy under tough conditions
  • Mediocre transient response at 3.3V

Factors to Consider Before Buying the Best PSU for AMD Ryzen 9 5900X

The power supply is one of the most challenging components for first-time builders. They don’t really contribute to your system’s aesthetics, and they won’t increase your framerate. There is no component more vital to the long-term health of your system than your power supply. PSUs are important, even if they are not as glamorous as a new graphics card, processor, or any other component of your PC.

Power supplies are the beating heart of your PC, so if you buy a cheap one, you put your entire system at risk. When it comes to upgrading your PC, your power supply can limit your options, so you should look towards the future when choosing your next power supply. Before buying the best PSU for AMD Ryzen 9 5900X, here are some factors to consider.

Look for 80 Plus Certified PSU

An 80 percent efficient power supply delivers 80 percent of its rated wattage to your system while losing the other 20 percent as heat. Manufacturers submit power supply samples for testing and certification to an independent body under the 80 Plus certification program. To earn the 80 Plus certification, the supply must be at least 80% efficient at three load levels, namely 20, 50, and 100%.

However, power supplies with higher certification tiers tend to be more expensive. If you’re a user with average needs, you’re probably better off sticking with a simple 80 Plus or 80 Plus Bronze level unless you find a particularly good deal on a Silver or Gold PSU.

Don’t Go For Cheap PSU

If your computer parts consume a lot of wattages, make sure the Power Supply Unit can provide at least 30% more than that. Although PSUs aren’t very expensive when compared to other parts, most people go cheap for the same reason. Power supply units affect every part of your computer system and can fry circuits in the event of a power surge.

When it cannot keep up with the electrical demands of your machine, the cheap power supply can ruin your performance. Running it hard and letting it fail quickly will cost you more in the long run. You are risking permanent damage to your other components if you buy a cheap power supply

The Number of Power Connectors

When shopping for an ideal PSU, you should also consider the number of power connections. Normally, mainboard power supplies are 24-pin (20 + 4) while CPUs and GPUs have 8-PIN (4 + 4) and 8-PIN (4 + 6) power connectors, respectively. Additionally, if you plan to increase the number of graphics cards or SATA hard drives at some point, you should also consider the number of D-type and SATA interfaces. This will allow you to reserve some power ports.

Choose the Cables Wisely

There are three types of cabling: Hard-Wired, Semi-Modular, and Fully Modular. 

  • In a Semi Modular PSU, some cables (e.g. motherboard and CPU cables) are permanently attached, and others (e.g. PCIe, SATA, and Molex) are removable. In terms of cable management, modular PSUs are a major advantage. 
  • The Modular Power Supplies allow the builder to attach (or detach) cables as they are needed. Modular PSUs allow builders to only use the cables required for the build, which reduces the amount of clutter in the case. 
  • The Hard-wired PSU contains the cables that are connected to PSU. These cables cannot be detached or changed.  Although this setup is cheaper than the other two cabling options, it is limited in plugs and is not suitable for customizing.

Fan Noise

Power supplies generate heat. Fans are needed to keep them cool and running efficiently. The quietness of your PC will depend largely on the environment in which it runs. A PC that runs in a quiet space may benefit from larger fans that spin more slowly to move the same amount of air. As far as power supply cooling is concerned, there aren’t any real standards, so you’ll need to compare marketing materials for your options.
