SilverStone has introduced its latest fanless power supply. The NightJar NJ600 PSU is the company’s most powerful silent PSU yet. Furthermore, the unit is rated for 80 Plus Titanium, meaning that the product is also very efficient.

The SilverStone NightJar NJ600 is ATX12V V2.4-compliant PSU that is rated for a 600 W total output and complies with the the 80 Plus Titanium requirements, which indicates that it is at least 94% efficient under a 20%, 50% and 100% load as well as at least 90% efficient under a 10% load. Getting the 80 Plus Titanium badge is a big deal for a relatively high-wattage fanless PSU as this enables to take advantage of energy efficiency of modern PC hardware while staying completely slient.

SilverStone NightJar NJ600 Output Specifications
Rated Combined
+3.3V 20 A 66 W
+5V 20 A 100 W
+12V 50 A 600 W
-12V 0.3 A 3.6 W
+5Vsb 2.5A 15 W
Total Power 600 W

In line with expectations, the SilverStone NightJar NJ600 features a modular design and is outfitted with two EPS12V connectors that make it compatible with high-end desktop motherboards (AMD Threadripper, Intel Core X) as well as 2P server/workstations platforms. Other connectors include four 6/8-pin PCIe auxiliary power connectors for graphics cards, six SATA power plugs, five Molex power outputs, and one FDD connector. All the cables are flat for greater flexibility.

When it comes to operating temperatures, the NightJar NJ600 can work at up to 40℃ and is rated for 100,000 hours MTBF. To ensure safety and reliability, the PSU also supports over current, over power, over/under voltage, over temperature, and short circuit protection technologies.

The SilverStone NightJar NJ600 (SST-NJ600) is already listed at the manufacturer’s website, but at present is not yet available from retailers. Considering the fact that the NJ600 is silent and highly-efficient, expect it to feature a premium MSRP, but its exact price is yet to be named.

    :) looks nice. nightjar is an appropriate name too.

    I believe using this in my South Asian home is outta the question. Avg temps can reach up to 48C indoors when its a blackout :/ and my UPS/backup power can just support the PC.

    It'll be fine at moderate workloads at 48C ambient. But I wouldn't do any hardcore production work at that temp. Not that you would be during a blackout on UPS power.

    I have a Nightjar 450w SFX power supply in my FT03-mini. Temps in my office can approach 40C in the summer here in Chicago, though granted the entire system is mostly idling during that time.

    It's been reliable for years running a Xeon E3-1230v3, 16GB RAM, 1TB SATA SSD, 2TB 2.5", 6TB 3.5", GTX 970 blower, and water cooling on the CPU. The only fans in the case are the video card blower and the 120mm at the bottom for the radiator that blows up, over the motherboard\ram and a little into the PSU.

    I am Australian.
    Temperatures can hit 50'C ambient here where even the tar on roads starts to melt.

    I think they should have included a fan "just in case".

    Fanless power supplies have always been for a niche that knows what they are doing.
    And I'd argue they are exclusively for people with air conditioners.

    The pin counts on the M/B connectors seem off: 18 on the big one, 10 on the small one, 28 total != neither 24 pins for ATX, nor 24 + 16 for ATX & 2x EPS.

    The EPS connections are more likely multiplexed on the CPU/PCI-E plugs, in which case stating both 2x EPS _and_ 4x PCI-E is not quite accurate since all 6 can't be used together: either 1x EPS & 3x PCI-E, or 2x EPS and 3x PCI-E (or 0x EPS and 4x PCI-E, but I don't really see that happening: why would you have 2-4 GPUs with a CPU/mobo that doesn't need any EPS (does that even exist anymore?))

    Really minor criticism but I wish they would have used black PCB instead of having glimpses of green poking out.
  • Icehawk - Wednesday, October 3, 2018 - link

    I have two fanless PSUs and they are just awesome - once you get rid of the PSU fans and mechanical HDDs most of the noise a PC generates disappears. I do hear my GPU spin up for some games but at that point the game audio covers it anyway. Glad they have a 600W version as it looks like GPU wattage is creeping up again.

    I have a HP Stream 11 with a Bay Trail CPU. It uses like 12W under full load when gaming. It has no fans and makes no noise whatsoever. If you want quiet, you just have to pick the right hardware from the start and then run software within reach of said hardware.

    fanless , hi-power and efficient go together any way dont they? eg any PSU that is fanless will by definition be quite efficient.. It would be better if they did asymetric PSU , that are more efficient at 5,10,and 20% than at 90%... and no Blinking lights ,Phew: Good work , like the Nj450 sfx meself.
