Its a totally silent SFX-L power supply. Its expensive, but it is highly spec'd. Worth it ? SilverStone was the first to release a passive SFX-L unit based on a platform provided by Enhance Electronics. The NJ450-SXL is fully modular, highly efficient and its overall performance is very good. It is built like a tank since it is surrounded by heatsinks and the only downside is the stiff price tag, which is partly due to the innovative design.

SilverStone was the first brand to fully support the SFX and SFX-L form factors by releasing a great number of relevant models. This brand is devoted to bringing the smallest physical power supplies. Even its ATX form factor models feature increased power densities, thanks to their compact dimensions.
