Silverstone has expanded their Nightjar family of power supplies with the addition of a new SFX-L class sized silent PSU, the NJ450-SXL. The new PSU, according to Silverstone, is the first ever fanless SFX-L design. The 450W PSU is said to use premium components, achieves an 80 Plus Platinum level of efficiency, and can output nearly 38A on the +12V rail, all in a fanless 0 dBA aluminum chassis measuring in at 5.12” x 2.5” x 4.92” (WxHxD).
The black chassis is made out of an extruded aluminum shell with fins running front to back on all four panels, serving as a heatsink to remove heat away from the internal components. The other faces of the PSU contain the connectors for outputs and the power plug & on/off switch respectively. The unit does not appear to be vented so the integrated heatsink/chassis will have to do all the work getting the heat out of the device. That said, it is rated to deliver 100% load 24/7 while operating up to 40C.
The Nightjar NJ450-SXL is 100% modular using short flat cables which can make for an easier attempt at hiding the wires. Outside of the 4-pin EPS and four 6/8-pin PCIe connectors measuring in at 400mm/~15-inches, the rest of the cables are 300mm/11.8-inches in length so these may not reach in the largest of cases. Additionally, the NJ450-XSL includes eight SATA connectors, three 4-pin Molex connectors, and a 4-pin legacy floppy connector (100mm length). The power supply can support a single high-end video card or multiple mid-range cards with its connections.
