XPG Core Reactor 650W

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, only a few PSU brands own exclusive rights to OEM platforms.

Corsair psu are 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 faced competition against many renowned power supply units in the market. It is emotional that still, it manages to win the race. In light of facts, historically, XPG hasn`t been such a power in the market.

It has hired some professional people for this job. A 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. The lines do not have in-line capacitors, making string lodging harder than it has to be. The only debit in this unit is the brace of EPS connectors hosted on the exact 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 on the platform.

The price of this power supply made it eligible for our Best budget power supply for AMD Ryzen 5900X category. Shortly XPG Core Reactor 650W includes in the line of the Best PSU for AMD Ryzen 9 5900X.

Our Verdict

The power supply is able to deliver full power at a high temperature of 47 degrees Celsius, which is a good sign of its durability and reliability. The fully modular design and high efficiency make it a good choice for a high-end system, and the 10-year warranty offers peace of mind.

The main downsides to the XPG Core Reactor are the fact that the two EPS connectors are on the same cable, which could be a tight fit in some setups, and the slightly higher price point.

Fractal Design Ion SFX 650W Gold

Silverstone was the first brand that took some severe interest in SFF PSUs, with the wealthiest related products portfolio. In the meantime, until Fractal launched these SFX Gold units, it had nothing to show for this order.

Nevertheless, 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 more giant cooling suckers and better tailwinds.

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 also allow for advanced capacity units 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 are 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.

Seeing a ten-year bond in an SFX power supply isn’t so frequent. Only Seasonic gave it until now, but since those Fractal Design power supplies share the same platform, they are covered by the same warranty.

Our Verdict

Our verdict on the Fractal Design Ion SFX 650W Gold is also positive overall. The inclusion of an SFX-to-ATX mounting bracket is a nice touch, and the power supply is $10 cheaper than the cheapest equivalent wattage competitor. It is also highly efficient and comes with a 10-year warranty.

The main downsides to the Ion SFX are the split ATX 24 pin at the PSU end, which could be a tight fit in some setups, and the high inrush current with 230V input, which could potentially cause issues with some systems.

However, overall we found the Fractal Design Ion SFX to be a reliable and high-quality power supply that is well worth considering for a high-end system.

Corsair CX450

The minor 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 platform.

The only way to tell them piecemeal is through their RPS figures and 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 tariffs and keeps its price label low. The GW platform also serves other areas. 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. Such a performance on a low budget makes Corsair CX450 one of the Best PSUs for AMD Ryzen 9 5900X.

Our Verdict

The power supply has good efficiency for a low-cost model, and the rifle bearing fan is a nice touch. The soldering quality is also excellent. The main downsides to the CX450 are the single PCIe connector, which limits expansion, and the short distance between peripheral connectors, which could be a tight fit in some setups.

However, overall we found the Corsair CX450 to be a reliable and high-quality power supply that is well worth considering for a budget build.

NZXT C850

NZXT has been in business for over a decade now and aims to be the best manufacturer of computer components. The company offers some of the most excellent 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 with 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 that the C850 can be used worldwide without flip switches.

The C850 silent mode is the most prominent feature, in addition to its impressive TEN-year warranty.

Under low loads, it acts as a toggle switch, which causes the fan to run at zero RPM. In some situations (sitting in front of the computer, doing office work, etc.), the PSU fan automatically shuts off to keep things quiet. The PSU fan will involuntarily ramp up to keep it cool as soon as you start a game or render that consumes a lot of power.

The NZXT C850 is a mid-range power supply designed to satisfy high-end gamers and PC enthusiasts, including 80 Plus Gold efficiency and a single +12V rail. NZXT’s C850 PSU provides 850 watts of power at 12V while having excellent voltage regulation. Because of its high efficiency, it’s a great choice for gaming systems. This PSU is undoubtedly one of the best for AMD Ryzen 5900X.

Our Verdict

I have personally used the NZXT C850 in my own high-end system and have had a positive experience overall. The power supply has a long hold-up time and low inrush current, which have contributed to its reliability in my setup.

The fully modular design has also made cable management easier. The main issue I have encountered with the C850 is some noise under tough conditions, but this has not been a significant issue for me.
