SilverStone creates another milestone for small form factor PCs once again with a Nightjar fanless power supply entry, the NJ450-SXL. In pursuit of crafting the ultimate SFX-class sized silent PSU, SilverStone engineers employed premium components and innovative engineering to achieve the first ever fanless SFX-L design. With its 80 PLUS Platinum level of efficiency reducing wasted heat, this noise-less unit can maintain stringent electrical performance up to 40C operating environment while delivering powerful +12V output of 37.5A for high-end system usage. Included with the NJ450-SXL is a set of flexible, flat modular cables designed for small form factor PCs to make assembly easy and to improved case airflow. For professionals and SFF enthusiasts looking to build compact PCs or workstations for specialized settings such as recording studio or sound-optimized laboratories, the NJ450-SXL with its quality, stability, and reliability, are sure to satisfy.Features - Fan-less thermal solution, 0 dBA acoustics - SFX-L form factor for use in small form factor computers - High efficiency with 80 PLUS Platinum level of efficiency - 100% modular short cables with flexible flat arrays - 24/7 continuous power output with 40? operating temperature - Class-leading single +12V rail - PCI-E 8pin and PCI-E 6pin connectors support Specifications - Model No.: SST-NJ450-SXL - Max.
