Features    [ Edit | History ]
Introduction
As a step-up from the venerable ST30NF, SilverStone’s first fan-less power supply, the newer Nightjar series ST40NF achieves its continuous power output up to 400W. This is the power level that has become the mainstream application for a new generation of silent computers. By again combining superior server-level components and advanced technical design, the ST40NF has high reliability and efficiency. It can maintain 82%~86% efficiency at 20%~100% loading, earning it 80 PLUS Bronze certification. Coupled with single PCI-E 8 pin connector and dual PCI-E 6pin connectors, the ST40NF can also support high-end graphics cards if needed. For silent enthusiasts or audio/video professionals, getting this power supply will certainly be one of the most important upgrade in completing a truly silent computing environment.

Pros
Dead quiet. Fanless. Zero DB acoustics.
400 W. 100 W more than the previous model.
Cables layout in net wrapping.
80 PLUS Bronze certified.
Plenty of cables.
Really solid.
Cons
Price. I want quality though. In my case I don't mind paying for quality as I know it's going to last longer.
Lower wattage power supply. 400 W is enough for my needs. If I need more then I would be a second one for a total of 800 W.
Summary
Cables comes wrapped in nets making it easier to install.
Plenty of cables, including PCI-E (not always found on lower wattage, passive PSUs).
Solid build quality is evident.
High-end design, based on a LLC resonant primary and DC-DC converters on the secondary.
Highly overspec’ed components. The quality shows again.
