Budget Power Supply for Ryzen 9 5900x
Brand: Corsair | Output: 450W | Efficiency: 82% at full load | Form Factor: ATX | Cooling method: Air | Cooling fan: 120mm Rifle bearing fan | Power supply design: Non-Modular | Warranty: 5 Years
✓All types of protection features
✓Has a great soldering quality
✗ Only one PCIe connector
✗Short-distance peripherals connectors
We have already reviewed some premium Corsair’s PSUs from the AX series and RMX series. In contrast, the Corsair CX450 is telling a different story. It’s for those customers who want a budget power supply for Ryzen 9 5900x without compromising the performance.
Interestingly, this model is manufactured under two names, Great Wall and Channel Well Technology, and this fact often makes the buyers confused. We will try our best to introduce you to this masterpiece using the simplest terms.
It seems that there are more differences between both types of models rather than having the same similarities–we will try to tell you all of those in a one-by-one manner. The Great Wall (GW) unit can provide 85-88% efficiency whereas the Channel Wall Technology (CWT) can go up to only 85% power efficiency.
Both use the same 120mm rifle bearing fans but the GW unit has a noise level of about 35-40 dBA against the CWT’s 25-30 dBA maximum sound.
Moreover, both types of PSUs are quite hard to differentiate unless you don’t know some factors that are going to be discussed now. You can check the built type with the reference designator which is RPS0053 in the case of the CWT version and RPS0063 for the GW power unit.
On the other hand, some similarities between both include the same resonant converters, voltage regulation modules, five years warranty, and same fixed cables which is a drawback of the other units.
Final verdict: The Corsair CX450 is the perfect PSU for you if you want to buy an affordable product for the Ryzen 9 5900x power consumption. But there are two manufacturers of the same type of 450W PSU where the GW unit is more efficient than the CWT in terms of efficiency but loses for producing more noise. If these make you confused, you can go for the EVGA 450 BT which is available at pretty much the same price.
Fractal Design Ion SFX
Best Overall PSU for Ryzen 9 5900x
Brand: Fractal Design | Output: 650W | Efficiency: 87% at full load | Form Factor: SFX | Cooling method: Air | Cooling fan: 140mm FDB bearing fan | Power supply design: Full Modular | Warranty: 10 Years

✓A massive ten-year warranty
✓Flexible and high-quality cables
✓Full modular unit
Fractal Design has got a name for manufacturing high-end cooling solutions and even blissful power supply units. If we look at its Ion SFX series, it shares a few same features and specifications as the SilverStone’s SFF PSUs.
It means you can enjoy the same SFF’s cooling performance and efficiency with this SFX series. Interestingly, the Ion SFX 5650G matches the quality and execution with the pricey Corsair SF600 and Seasonic Focus SGX-650 and the same-priced EVGA 650 GM.
Two models are there in the series with 500W and 650W capacities where we have the top-of-the-stack, the 650W version. Thes series falls in the 80 Plus Gold verified category so you can expect a smooth 90/87% efficiency in the 50/100% load conditions.
Remember that the Premium Japanese 105°C capacitors play a pivotal role in getting such an impressive level of efficiency and durability. With so much effort, it becomes the best overall PSU for Ryzen 9 5900x.
As I mentioned in the buying guide section, protection is one of the must-have factors for all PSUs to ensure safety and stability. Well, this one is fully-protected from the abrupt voltage abruptions with all types of protections related to voltages, short circuits, and irregular current.
Further, this unit is fully modular and comes with flexible cables that feature UltraFlex technology. In addition, these cables have high-count wires that are effective and easy to install.
Final verdict: The full modular Ion SFX 650W has a long list of impressive features including sound-less performance, a large fan, and flexible cables. Not only that, it beats the famous Corsair SF600 and Seasonic Focus SGX-650 while having a lower price tag.
In addition, it features all types of protection for safety and long-lastingness. So, if you want an all-rounder and efficient power supply unit without spending much, this unit is a perfect match for you.
NZXT C850 850W
Best 850W Power Supply for Ryzen 9 5900x
Brand: NZXT | Output: 850W | Efficiency: 87% at full load | Form Factor: ATX | Cooling method: Air | Cooling fan: 135mm Fluid Dynamic bearing fan | Power supply design: Modular | Warranty: 10 Years

✓Fully modular PSU
✗Mediocre transient response at 3.3V
NZXT has been in the market for more than a decade and has kept discovering and manufacturing updated computer-related components. The brand’s C850 power supply unit provides a mid-ground between lower 450W and top-tier 1000W products with an 850W of DC power output.
Compared with the RM850X, this PSU is roughly $50 cheaper but doesn’t give that much difference in performance–the absence of RGB lighting plays a key role in keeping the price lower.
Moreover, the C850 is quite similar to the NZXT E850 with several similarities but lacks the CAM digital integration features. Quality-wise, the brand has embedded all-Japanese capacitors along with other components to make a high-quality construction.
In addition, it’s an 80 Plus Gold approved PSU so it can provide overall 87% power efficiency at full load and a single +12V rail. It’s undoubtedly the best 850W power supply for Ryzen 9 5900x with all those appealing aspects and efficiencies.
Apart from that, you get all types of connectivity options including the six SATA power and six peripherals connectors. The cherry on the top is that it has a cable for every connector that can be utilized to perform the related operations.
There is a 135mm Fluid Dynamic Bearing fan, excellent, but it gives 44.5dBA maximum noise which is slightly disappointing. However, the silent mode can help us to reduce this sound very well but still, it’s a drawback of having this unit.
Final verdict: The NZXT C850 is a great mid-ground 850W power supply unit between the low-end 450W or 650W and some top-tier 1000W PSUs. Moreover, it’s an 80 Plus Gold certified unit so you can expect a stable 90/87% power efficiency at half/full load, respectively. There are some drawbacks in this unit like the absence of CAM digital integrations and noisy operations but overall it’s best in terms of power efficiency and value for money.
