SilverStone Nightjar ST45NF 450W Fan-less PSU Review

Author: Lee Garbutt
Manufacturer: Silverstone


The SilverStone Nightjar ST45NF fan-less power supply supports the ATX12V v2.3 and EPS12V standards and is rated for a combined, continuous output power of up to 450 watts (500W peak) when operating at 230 VAC.  Note: When operating on 115 VAC line power, the combined, continuous output capacity is limited to 400W (450W peak).  The DC output specifications also require an ambient air temperature of 25°C or less (internal case air temperature), which is considerably lower than what is typically needed by the majority of fan-cooled PSUs.

The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC, which makes the unit more environmentally friendly.  The ST45NF PSU provides a single +12V output rated for up to 35A (420W).
