PSU: SilverStone Nightjar 400W Zero dBA
Fanless Power: SilverStone Nightjar 400W Zero dBA
SilverStone's Nightjar 400W Zero dBA is fairly heavy as a result of its completely passive design. Thermally, this power supply should work really well in the Temjin TJ08-E because of how it's built. The Nightjar’s current street price of $160 is high, but within reason. We won’t need the PSU's 400 W output by a long shot. Of course, we know that wasting power by buying too large of a power supply (and consequently not optimizing for efficiency) is a problem). But we're getting as close as possible with SilverStone's Nightjar 400W Zero dBA. It’s getting hard to find a PSU under 400 W these days, after all.

Installing the power supply takes some effort, and involves taking off the case’s top panel (the hard part) and then placing it inside the chassis from above (the easy part). The PSU's sharp edges can scratch the enclosure's finish very easily, so handle the hardware carefully during installation.
After the PSU is in place, it’s fastened from the back with four included thumb screws, making it easy to finish the installation. Too bad the screws and power supply aren't available in black, though.
The 400 W version of this PSU doesn’t have a status LED (the 500 Watt version does). Instead, the on/off switch lights up when the PSU is turned on. Using a motherboard that supports ErP/EuP, we measured an off-mode power consumption of only 0.4 W.
