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?"

Introduction and Features

2-NJ-520-Banner.jpg

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.

Here is what SilverStone has to say about their new fanless 520W PSU: “SilverStone’s Nightjar NJ520 is a fanless power supply that offers a whole new experience of quietness and stability. 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.

SilverStone Nightjar NJ520 Power Supply Key Features:

•    Fanless thermal solution, 0 dBA acoustics
•    High efficiency with 80 Plus Platinum certification
•    100% Modular cables
•    Strict ±2% voltage regulation and low AC ripple & noise
•    Class leading single +12V rail, up to 43A (516W)
•    Four PCI-E 6+2 pin connectors
•    Protections: OCP, OVP, OPP, OTP, UVP, and SCP
•    Universal AC input and Active PFC
•    MSRP $149.99 USD

Introduction and Features

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 later last year released the SST-ST50NF 500W fanless power supply, which is the latest addition to the Nightjar series. We are a little late to the party in reviewing the ST50NF but after talking with the good folks at SilverStone it appears the wait was worth it as they have continued to tweak the design in recent months to improve AC ripple suppression on the DC outputs.

Here is what SilverStone has to say about the Nightjar 500W fanless power supply: The fanless Nightjar series power supplies are long favorites for professionals and enthusiasts alike that require noiseless power solution with no moving parts. With increasing power demands required from modern computers, SilverStone engineers have once again created another fanless power supply with leading output level in ST50NF. With 500W of continuous rating, near 80Plus Silver efficiency, ±3% voltage regulation, single +12V rail, multiple PCI-E connectors, and full host of safety features, the ST50NF is a great choice for mission-critical systems that need to operate in noiseless or dusty environments.

• Compliance with ATX 12V v2.3 and EPS 12V Specifications
• Strict ±3% voltage regulation
• PCI-E 8-pin and PCI-E 6-pin connectors
• Powerfull class-leading single +12V rail (38A)
• Aluminum construction
• Server-level components
• Universal AC input (100~250V) with Active PFC

Editor’s Note: Fanless PC power supplies occupy a niche market and are targeted towards users who want a silent power supply for use in noise-sensitive areas or who need a power supply that can survive in a dusty/dirty environment that might choke and kill a conventional fan cooled PSU. Fanless power supplies rely on convection cooling and still require airflow in and around the power supply chassis to carry away the waste heat. So while the power supply itself may not have a fan, the computer enclosure must still have some means of creating airflow to keep the CPU, GPU and PSU cool. The last thing you want to do is put a fanless PSU in a closed enclosure without any fans or airflow!
