Review

Many people want to play PC games at the highest settings but don’t want to pay for the high-end power supply required to do so.

If you want to be able to play at the highest settings but don’t want to spend $200 or more on a modular power supply, you might be interested in this NZXT C850 power supply review. This unit can offer features you’d expect from much more expensive power supplies, like quiet operation and quality construction that will last many years without fail, without breaking your budget.

  • The NZXT C850 is a highly efficient, full modular ATX power supply with a single +12V rail. The unit has 24 pin and 8 pin connectors, and a pair of EPS connectors to provide connectivity to an advanced computer system. It has an 80 Plus Gold certification which means it operates with an efficiency rating of at least 85% at 20%, 50%, and 100% load levels.
  • The 8-pin connector included on Ryzen 9 5900X is for future upgrades and it was designed in a way to offer compatibility with older motherboards. The additional PCI-Express x4 slot gives you more flexibility in case you need to add more powerful GPUs or SSDs without having to sacrifice any PCIe slots from your motherboard. We recommend using two high-quality eight-core processors together, so make sure that your power supply can handle at least 1600 watts of maximum load.

The NZXT C850 is an 80 Plus Gold rated PSU with a 10-year warranty. It’s truly modular, with no extra frills (such as RGB LEDs), but it gets everything right where it counts. The box comes with everything needed to install in a typical ATX case.

All wires come neatly organized in tie-wraps and zip ties, leaving no questions as to what goes where when you open it up. All modular cables are labeled, so there should be no confusion.

There is nothing flashy about their packaging or marketing materials, but it is all very efficient and easy to use; exactly what you need when dealing with a product that needs attention to detail.

Drawbacks

Although there are not any significant drawbacks to note, we would have liked to see a longer warranty. The 10-year warranty period is not impressive at all considering that it’s only applicable if you register your product with NZXT.

If you choose not to register your product, then it will only be covered by a 2-year warranty. Although short compared to other models on our list, still, it’s better than nothing.

Pros

  • Noise-free operations
  • Durable construction
  • 24 pin connectors include EPS connectors
  • Powerful GPU and SSD
  • Budget-friendly
  • 10-year warranty

Cons

  • Customer support is poor
  • Some buyer reports died down the issue

The NZXT C850 is built for a custom PC and high-quality PSU. Because it really offers excellent value with its noise-free operation, durable design, and budget-friendly at just $120 for a gaming PC.

7. Fractal Design Ion SFX 650G Gold Certified 650W Full Modular Power Supply

Features

  • 90% efficiency
  • 6+2 pin PCIe connectors
  • Ultra-Flex cables 
  • Ease of installation
  • Silent operation with semi passive mode

Review

All-in-One PCs are great for desktops as they require less cable management, but they generally make it much harder to upgrade components in the future, such as the power supply or motherboard.

Fractal Design’s latest power supply, the Fractal Design Ion SFX 650G – 80 Plus Gold Certified 650W Full Modular SFX-L Power Supply, aims to solve that problem with its ultra-small form factor and fully modular design.

Fractal Design’s Ion was specifically made for micro ATX cases and will not overhang your motherboard or overheat due to improper ventilation.

  • Fractal Design has launched their new power supply called the Ion SFX 650G which is made for mainstream gaming systems that utilize the new AMD Ryzen 9 processor, but it’s also compatible with Intel CPUs too. The MSRP on this 650W power supply is $126 which makes it one of the more affordable high-end SFX-L units currently available on the market today.
  • This powerful, small footprint power supply is only 150mm long, making it an excellent choice for smaller systems. The power supply also supports a fully modular cable management system, making it easy to install and helping to keep your case neat and tidy. And thanks to its 80PLUS Gold certification, at typical loads this PSU achieves over 90% efficiency. This means less heat generation and lower energy bills (and less greenhouse gas emissions).

It has a single 24 pin motherboard connection and a pair of 4+4 pin CPU connections. It also has two 6+2 pin PCIe connectors, three 6/8 pin graphics card cables, eight SATA power connectors and four Molex peripheral power connectors. As you’d expect from a power supply of its caliber, it comes in an impeccably designed and sturdy box. Opening it up revealed an individually bagged power supply, some papers, two cables, one AC cable and one modular cables. The packaging was top notch.

Drawbacks

While 650 watts is more than enough power for any gaming PC built today, and even most entry-level workstations, there are a few drawbacks. First, as with all modular PSUs in general it requires you to buy every single cable individually.

If you’re building a cheaper PC or a very small form factor (SFF) system where space is at a premium you might consider buying another fully non-modular unit with plenty of cables included. You need to get power from somewhere.

Pros

  • SFX to ATX bracket mounting
  • Perfect flex cable
  • Lightweight and solid construction
  • Higher efficiency under loads
  • Value for money

Cons

  • Some users report noisy operations under heavy loads
  • With 230 V input current rush is high which causes danger

The Fractal Design Integra Modular PSU is a superb choice for building a mini PC. It offers incredible value, particularly if you don’t plan to overclock your CPU because of high efficiency and less energy consumption.

8. Corsair SF Series SF 450 Watt Certified Fully Modular Power Supply

Features

  • 80 PLUS Gold certified
  • Zero RPM Fan Mode
  • 7-year warranty
  • 92% efficiency
  • SFX-to-ATX bracket

Review

In this Corsair SF450 review, we’ll discuss whether or not the PSU is the best power supply for Ryzen 9 5900x along with its many other key features and specifications that you should be aware of.

Do you think it deserves to be the best power supply for Ryzen 9 5900x?  This fully modular power supply from Corsair offers excellent performance and quality for the price, and it just might have what it takes to be one of the best power supplies on the market today.

The model that we will review today is the 450 Watt variant, which has a single +12V rail and is rated for powering up to a single VGA card setup and two hard drives.

  • The Corsair SF450 is a small form factor power supply with some serious power. It comes in at 450 watts, which should be more than enough for any single graphics card system. And with an 80 Plus Gold rating, it’s likely to be one of the best PSUs available for use with a Ryzen 9 5900x CPU. The unit is fully modular, which allows you to use only those cables you really need (rather than having them bundled inside your case).
  • It also uses synchronous rectification to enhance efficiency, which means that both of its +12V rails run at 100% all of the time. According to our tests, it’s around 92% efficient at loads below 25%. That makes it a very good option for Ryzen 5900 processors. The wires are all sleeved nicely, and you get a number of accessories in addition to what you normally would see with a PSU. This includes screws for mounting, zip ties for organizing cables, Velcro cable management stuff, and even an extension cable for your 24 pin motherboard connector.

The packaging of the Corsair SF450 is pretty standard, at least on paper. A generic black box with a big picture of the power supply covers all sides of it, which looks nice but doesn’t really offer any information about what’s inside.

The packaging does mention that it is fully modular and comes with a 7-year warranty, however, so you don’t have to worry about Corsair not backing their product here.

Drawbacks

This power supply is pretty expensive for a 450W unit, but you should expect that from a fully modular power supply. Also, it’s only 80 PLUS Gold certified. We would like to see an 80 PLUS Platinum rating or better to match its price tag.

But you’ll be more likely to have more usable cables, which is something that has been on many people’s minds since Corsair updated their high-end power supplies by making them fully modular in 2016.

Pros

  • Sleeved cable deigns
  • High-quality materials
  • Silent operations
  • Solid durable design
  • Enough connections

Cons

  • A little on the expensive side
  • Some turn off overshoot

The Corsair SF450 is a great fit for high-end builds that need more power because it offers good value with its 80+ Gold certification, fully modular design and semi-passive operation which make it well worth its premium price tag.

Buying Guides

When choosing the best power supply unit (PSU) for your PC, don’t rely on the wattage alone look at the efficiency rating as well. In this guide, we’ll explain what you should look for in a power supply unit if you want one that performs efficiently and won’t break the bank.

Efficiency vs Wattage

Today’s energy-conscious consumers want their products and appliances to be as energy-efficient as possible while maintaining high performance. With that in mind, you’ll want to look at two things when buying a power supply: efficiency and wattage.

Efficiency indicates how much energy is lost between your home and your power supply, while wattage is a more straightforward measurement of how much electricity a device can use. You’ll want to match up your wattage needs with an appropriate efficiency rating; if you need 1,000 watts but only have an 80% efficient unit, then 800 watts will make it through and 200 will be wasted.

Noise Level and Fan Speed

The number of fans, their diameter, and how quickly they rotate all contribute to a power supply’s noise level. If you care about keeping your PC cool and quiet, look for a power supply with few high-speed fans.

This can often mean paying more upfront, but it’ll save you money down the road by reducing your energy bill (less electricity is required). And high-quality PSUs often come with a quieter 120mm fan that rotates slower while still cooling components adequately.

Modular Cables

Your power supply should have modular cables. This makes cable management much easier and also helps you keep things tidy if you add or remove hardware from your PC. It’s not worth getting a power supply without modular cables, so look for that feature when shopping around.

There are two main types of cabling: hard-wired and modular. Hard-wired means there is no way to detach them; they stay attached at all times. Modular means they can be detached, allowing you to rearrange them as needed.

Power Output

The first thing you need to think about when buying a power supply is how much juice it’s actually putting out. You can tell by looking at the wattage rating, which is listed on every power supply and comes from its peak power output.

The whole point of a powerful computer is to be able to use all that horsepower, so if you’re buying a very high-end CPU, you’ll want more wattage than a low-end processor would require.

Cost

Getting a good quality power supply is one of those things that you can always buy too cheap. You get what you pay for, so look at reputable brands like Corsair, EVGA, and Sea sonic when looking at components.

There are other products out there with solid reputations (like Rose will) but these three tend to be more widely recommended by enthusiasts.

Safety Features

Overloading a power supply can create a dangerous situation. Fortunately, most PC power supplies include some type of protection against overloading.

The standard is Over Current Protection (OCP). Many power supplies also offer Short Circuit Protection (SCP), Over Voltage Protection (OVP), and Under Voltage Protection (UVP). OCP/SCP are essential features that ensure your system remains safe, while OVP/UVP protect components from being damaged by incorrect wiring or from an incorrectly set voltage.

Specifications

It’s a safe bet that any decent power supply will have all of today’s basic connectors, such as 24-pin ATX, 4+4 pin EPS 12V and 6+2 pin PCIe. It’s also fairly common that you might need a special cable (or adapter) to support newer video cards or cases with built-in fan controls.

FAQs       

Is Platinum Better Than Gold PSU?

The majority of power supplies available today are rated as Gold or Platinum by 80 Plus. While these numbers aren’t foolproof indicators of quality, they can tell you whether a PSU is better than average (which is what matters). Platinum-rated PSUs deliver up to 90% efficiency at 50% load. Gold units match that rating at 20% load. If you have an energy-efficient system with an overclocked CPU and multiple graphics cards, it may be worth spending extra on a platinum unit. Otherwise, gold should do just fine.

What power supply do you need for Ryzen 9 5900X?

If you’re building a gaming rig, you know that building a powerful system starts with buying high-quality components. However, if you buy one of AMD’s latest processors, there’s no telling whether your power supply will be compatible. If you’re going to be installing a new processor and/or graphics card soon, you’ll want to do some research beforehand on what power supply will work best with your particular setup.

Are 750 watts enough for Ryzen 9 5900X?

The first thing to know about power supplies is that watts are not a good indicator of what your computer needs. Instead, it’s best to go by AMPs. A high-end power supply should have at least 40 AMPs or more. The one exception is when buying a modular power supply; those are built with fewer components and often don’t meet minimum requirements.

Final Thoughts

Choosing a power supply is no easy task. With hundreds of models available, it can be hard to find one that suits your needs.

Fortunately, there are several questions you can ask to make sure you get what you need when choosing a power supply for your Ryzen 9 5900x processor. we’ve decided to put together a list of our top 8 picks for the best power supply for ryzen 9 5900x. We picked these out because they have both high-quality ratings and great performance stats.

But if you are still confused about which one to buy, we would recommend NZXT C850 850-Watt PSU ATX Gaming Power Supply for Ryzen 9.
