SilverStone Nightjar NJ450-SXL PSU Review

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 1500 possible load combinations with the +12V, 5V, and 3.3V rails. The load regulation deviations in each of the charts below are calculated by taking the nominal values of the rails (12V, 5V, and 3.3V) as point zero. The ambient temperature is between at 30°C (86°F) to 32°C (89.6°F).

Efficiency Chart


The PSU’s efficiency is really high, putting to shame other Platinum and ETA-A PSUs. As you can see in the chart above, in the majority of its operation efficiency is above 92%.

We apply half-load for 10 minutes with the PSU’s top cover and cooling fan removed before taking photos with our modified FLIR E4 camera that delivers 320×240 IR resolution (76,800 pixels).

We notice that the PSU’s heatsink gets quite hot, especially in some regions, meaning that it does a good job expelling the heat.
