SilverStone puts lots of effort in the small form factor PSU category, and a few months ago released the Nightjar NJ450-SXL. It's the only passively cooled SFX-L unit available on the market today. It's based on an impressive platform, provided by Enhance Electronics. So it's not exactly a surprise that this power supply has been named as "CES 2019 Innovation Awards Honoree."
This title goes to products or technologies that score above the threshold set for a specific category, and the NJ450-SXL definitely sets a new standard in the small form factor category. So far, no other manufacturer has introduced a passive SFX-L unit, and besides dead-silent operation, the NJ450-SXL offers high performance as well, along with extremely high efficiency levels. After all, with a fanless product like this, the only way to deal with heat dissipation is to increase efficiency.
The NJ450-SXL will be on display, along with the rest of the nominees, at the Innovation Awards Showcase at CES 2019 in Las Vegas early next year.
The PSU is currently available wordlwide, with a recommended MSRPs of $189.00 for the US market, and €159.90 in Europe.
Its noteworthy features are:
- SFX-L form factor
- Fanless design
- LAMBDA-A++ noise certification by Cybenetics (the best in the scale)
- 80 PLUS Platinum and ETA-A (88-91 percent) efficiency certifications
- Fully modular (1x EPS and 4x PCIe connectors)
- 24/7 continuous power output at 40 ℃ ambient
