SilverStone recently took the wraps off of a new fanless power supply for small form factor (SFX-L) systems. The Nightjar NJ450-SXL is a 450W PSU that conforms to the 80 PLUS Platinum specification where it can hit up to 92% efficiency at 100% load. The power supply, which SilverStone claims is the first SFX-L fanless PSU, features an extruded aluminum outer shell with aluminum fins running front to back on the top, bottom, left, and right sides. It measures 130mm x 63.5mm x 125mm and weighs 1.52 kg (3.35 pounds).

The SFF PSU features a single +12V rail rated at 37.5A and is compatible with a single high end or dual mid-range GPU setup. It further features support for over current, over power, over voltage, and short circuit protection as well as active power factor correction (PFC) for cleaner AC input and more efficient power distribution to the components powered by the PSU.

The fully modular Nightjar NJ450-SXL features flat black cables that are fairly short (most of the cables are under a foot so no putting this bad boy in an E-ATX case!) to make cable management as easy as possible especially when it comes to airflow and shoving (I mean, uhm, organizing) them behind the motherboard tray to make the build look cleaner.

Notably, there are no vents on this power supply. Even so, SilverStone rates the PSU at operating temperatures of 0°C to 40°C while maintaining 100% load and 24/7 operation.

As far as supported connectors, the Nightjar NJ450-SXL features support for:

  • 1 x 24-pin ATX
  • 1 x 8-pin EPS
  • 4 x 8-pin PCI-E
  • 8 x SATA
  • 3 x 4-pin peripheral (think Molex style)
  • 1 x 4-pin floppy

SilverStone rates its new PSU at 100,000 hours MTBF at 25°C. It is not clear from its website what the pricing, availability, or warranty length will be (warranty is at least 1 year but it may be longer and the warranty page for the extended year(s) eligible products just hasn’t been updated). I am curious how this PSU will perform especially in a cramped SFF system. SilverStone claims that is silent at 0dBA, and hopefully the reviews can corroborate that. It looks like a good fanless option on paper, but I have a feeling it’s going to come at a premium price point!

Just built a Mini PC, used the thermaltake F1 suppressor and this would be a bad ass addition!

Hope you guys can review this!
