Just over a month ago Lee took a look at Silverstone's Fanless Nightjar PSU, giving it a Gold Award.  It has now arrived in [H]ard|OCP's torture chamber so you can see how well it works with a different system.  At the lowest load level of 25% of max the efficiency was a mere 89.79% but at 50%, 75% and 100% loads it stayed well above 90% and the temperature difference was 9C between the lowest load and the highest, impressive for a fanless PSU.  In the end not only was this the best fanless 500W PSU [H] has tested, it was the overall best 500W PSU they've seen, justifying the high asking price.

"What is more quiet than a computer power supply with a fan? You guessed it, a PSU with no fan. This unit has small footprint builds in mind featuring excellent Platinum efficiency, flexible flat cables, and of course no sound profile to speak of. Does the 520 watt rated SilverStone Nightjar hold up when we put it in the incubator?"

SilverStone was one of the first PC power supply manufacturers to design and market a fanless power supply for silent operation.  While many of their competitor’s fanless products have come and gone, SilverStone continues to build on their reputation and recently added the SST-NJ520 520W fanless power supply to the Nightjar Series, which currently includes three models: NJ520, ST50NF, and ST40NF. The Nightjar 520W PSU incorporates premium quality components and a state of the art design to deliver high efficiency (80 Plus Platinum certified), tight voltage regulation (±2%), and clean DC outputs. The new NJ520 fanless power supply comes with fully modular, flat ribbon-style cables that provide 4+4 pin ATX12V/EPS and 6+2 pin PCI-E connector support.

Its premium components and engineering helped it achieve 80 Plus Platinum level of efficiency, reducing wasted heat and enabling reliable operation without a fan. This noiseless performance can be maintained with stringent electrical characteristics even in 40°C operating environments.

As a versatile power supply, the NJ520 has a powerful +12V output of 43A for high-end system usage and its flexible, flat modular cables make assembly easy for improved case airflow. For professionals looking to build PCs or workstations for specialized settings such as recording studios or sound-optimized laboratories, the Nightjar series PSUs with their consistent emphasis on quality, stability, and reliability, are sure to satisfy.

Another unfortunately named PSU from SilverStone; the fanless 500W ST50NF

SilverStone have updated their NightJar series with a new model, the ST50NF, which is a 500W PSU that relies on passive cooling and so operates in complete silence.  With a claimed 80 Plus Silver rating this PSU is perfect for mid-range systems and servers, which you either need to operate silently or to use in dirty environments where fans can bring in enough dirt to cause shorts.  The design challenges that SilverStone faced when developing this PSU is obvious in its $200 price tag, which may discourage some.  [H]ard|OCP takes a good look at the newest NightJar from SilverStone here.

"SilverStone is back on our test bench today with a fully silent and fanless 500 watt computer power supply that is making some very impressive "Silver" efficiency claims. Beyond that, terms like "noiseless," "dusty environments," and "mission-critical" are thrown around. Now to figure out what a "Nightjar" is."

Introduction and Features

Kingwin just released their first fanless power supply, the Stryker Fanless 500W, which is rated for 500W and can be easily overclocked to 600W output with only a slight drop in efficiency. That makes the Stryker STR-500 one of the highest output fanless power supplies on the market today. And the Kingwin Stryker 500W Fanless power supply is certified 80 Plus Platinum with up to 92% efficiency. High efficiency is always good but it is critical for a fanless power supply to help minimize waste heat. Combine that with a good combination of fixed and modular cables and a 5-year warranty and we have a very interesting new product to review!

Kingwin has impressed us recently with several of their new power supplies, most notably the LZP-550W that we reviewed earlier this year, which won an Editor's Choice award. In addition to the new Stryker fanless PSU, Kingwin offers a complete lineup of PC power supplies ranging across seven categories along with PC chassis, external enclosures, docking stations, cooling systems, and accessories.
