5 Best Sfx Psu In 2022

If you’re building a small computer, there are few power supplies out there that can provide more bang for your buck than FSP’s Pro 450W SFX. This little unit provides ample power for most gaming and professional applications. Its single +12V rail is rated at 45A, which means it can support even top-tier graphics cards and other power-hungry components with ease.

This 450W 80+ Gold-certified PSU has every right to be considered one of – if not the best SFX power supply on the market. Awarded a gold certification and ensuring efficient power delivery at both low and high loads, FSP’s Pro 450W PSU is easy to recommend.

The 450W FSP SFX PSU is proof that you don’t need a 600W PSU for a high-end gaming system. And it’s not even just about power; size is an issue, too. The FSP Pro 450W SFX can fit into some really compact cases—and still pack enough power to support a graphics card like Nvidia’s GTX 1080.

When you’re building a gaming rig, there are lots of options for PSUs. We recommend starting out with a nice 500W PSU from a reputable brand like Thermaltake. The Smart RGB 500W ATX Power Supply is our pick because it delivers efficient power delivery at an affordable price and comes with some awesome RGB lighting as well. You can’t go wrong with $60 on Amazon.

Corsair’s SF450 Platinum is an excellent choice for a compact gaming PC. It’s pricey, but it’s 80 Plus Platinum certified for high efficiency and has an ultra-quiet 135mm fan. It also boasts full modularity and a five-year warranty.

The Corsair SF450 Platinum is our top pick due to its modular, full-size design and its six PCIe connectors, which give you flexibility for future upgrades. And unlike smaller PSUs—which can sometimes feel a bit flimsy—the SF450 has a full-size body that feels solid and well-built. The 120mm fan is also quiet during operation (though it does spin up during heavy use), and its semi-passive mode keeps it completely silent under light loads.           

The EVGA SuperNOVA 550 G3 offers excellent performance and value. With 80 PLUS Gold rated efficiency, over 90% (115VAC) / 92% (220VAC~240VAC) power factor correction, Japanese brand capacitors for superior durability, and a fully modular cable set to reduce clutter and improve airflow, this power supply is an outstanding choice. The ECO Intelligent Thermal Control System allows you to enjoy low operating temperatures with reduced fan noise during everyday operation.

The EVGA SuperNOVA 550 G3 Power Supply Unit is part of the ECO Intelligent Thermal Control System. The exclusive Cooling Fan System stops the fan completely at low to medium loads, giving you virtually silent operation. Lower temperatures mean longer component lifespan and optimized performance, even under extreme conditions.

The EVGA SuperNOVA 550 G3 is certified 80 PLUS Gold, which means your power supply isn’t just reliable—it’s actually efficient. Under certain conditions, it can be nearly 23% more efficient than a normal power supply. It also has an enthusiast-grade single rail design that delivers up to 88% efficiency on a multi-rail platform. So not only does it have low noise levels, but it will save you money in electricity as well.

The Corsair SF600 Platinum is undoubtedly one of the best power supplies you can buy. It’s part of Corsair’s SF line, which is specifically designed for gamers, and it gives you an incredible amount of bang for your buck. Its fully modular design means that cable management will be a breeze, and its 600W capacity means that it can support even high-end builds with ease. With 80 Plus Platinum certification, a 135mm fan with Zero RPM mode at low loads, semi-passive operation up to 40% load, and all Japanese capacitors on board (OEM: CWT), it’s hard to find anything wrong with this unit.

The best PSU you can buy today is Corsair’s own SF600 Platinum. Offering an 80 Plus Platinum rating and an up to 94% energy-efficiency rating, there’s a lot to like about Corsair’s flagship SFX power supply—even if its $160 price tag is a bit high for an SFX unit.

The Platinum Series is a top-to-bottom power supply series that offers something for everyone. Featuring up to 88% energy efficiency, Platinum Series PSUs provide cleaner and more stable power delivery than ever before. With support for forwarding voltages on all models, users can take advantage of smaller case sizes while still having enough headroom to make upgrades in the future. For those looking for an ultra-quiet PSU with a capacity large enough to support demanding systems, look no further than Corsair’s flagship SF600 Platinum.             

We’re a fan of Cooler Master PSUs in general, and their V850 Gold is no exception. It’s an 850W power supply with 80 PLUS Gold certification and a modular design for improved airflow. Another highlight is its SFX form factor, which means it can work in smaller cases with only one expansion slot available. The V850 will cost you $150 at most retailers, making it one of the more expensive options on our list. However, if you want to make sure your build has enough juice to keep up with high-end hardware, then you should definitely consider adding this PSU to your build.

For those that care more about style than anything else, however, it may be hard to look past Cooler Master’s V850 SFX Gold power supply. It comes in a snazzy gold color that will fit right into most mid-range gaming rigs, and it comes with enough wattage to allow you to expand your system in years to come.

The Cooler Master V850 SFX Gold is one of our top picks when it comes to SFX power supplies. It has a load capacity of 850W, with 6pin PCIe connectors, modular cables, and a 120mm silent fan. What’s even better is that it comes with a 5-year warranty and is 80 Plus Gold certified for efficiency.
