Packaging and Appearance
The Nightjar comes in a very sleek package and lies inside thick plastic foam. A change for Silverstone with this power supply and its package is that they're silver and not the usual black. We also find the standard manual, power cord, straps, and screws delivered with the package.
As stated, the power supply is silver, and it's perforated on all sides for better venting. The top is composed of a thick aluminum block with fins on the top. In between the fins are small openings to get air inside of the housing for additional cooling. Some electronic parts such as the coil from the primary stage have heat-conducting tape attached to transfer the produced heat to the housing, which then acts as a giant cooler for the inner parts. The power supply casing has an unusual amount of screws, which seems to be necessary to establish contact from all sides to provide the maximum cooling possible without a fan. The front has two LEDs; the first indicates the power supply is switched on since you don't hear it, and the second one shows the user if the temperature inside of the PSU is within operating limits.

See subject.Why do I want them to sell well?
Because more sales of high quality components = lower cost on great components due to economies of scale = better PSUs for everyone.

The power supply looks great, but nightjar is another name for chamber pot, something that you urinate in at night in order to avoid the long cold walk to the outhouse. What was the marketing department thinking???aos007 - Saturday, September 6, 2008 - link
That was the first thing I thought about as well (chamber pot), and English even isn't my first language. On the other hand I have certainly never heard of a bird named Nightjar nor would I think a bird name is appropriate for a PSU anyway. Not sure why would anyone think only "history buffs" would know this. Does anyone read or go to museums any more? I thought schools are supposed to have mandatory reading materials to make you read classics and have school trips to learn about history. Do they teach anything in school these days?AmberClad - Monday, August 25, 2008 - link
Looking at Wikipedia, it's apparently a type of bird too. Which I didn't know until now -- I've always understood it to mean "chamberpot" as well. Surprisingly, Wiki doesn't have that definition...Being a Taiwanese company, one would assume that they're not familiar with the unsavory alternate meaning of the word.

When was the last time anyone who might be considering one of these used an outhouse, a chamberpot, or a nightjar? Other than history buffs, don't think many would know it isn't a bird or just a made up name.JarredWalton - Monday, August 25, 2008 - link
I actually thought it was a term for a chamber pot as well, but it seems very few places on the web still list that meaning. I was happy to know that there's a bird called a Nightjar, as that sort of makes the name sensible (inasmuch as naming a PSU after a bird can make sense).AmberClad - Monday, August 25, 2008 - link
Aha, so I'm far from the only person who immediately thought of a chamber pot when I saw that name. I actually went and Googled the term "night jar" too, and I was also surprised at the relatively few references to it being a piss pot (there were some though, so at least I knew I wasn't going crazy).Btw, have you guys mentioned this to the Silverstone people? I'm not sticking a nightjar into my case. Everytime I see that product name, I get unpleasant mental images that I can't get out of my head.

I don't think it matters. Look at Nintendo and their "Wii Play" ads, if creepy men bringing their "Wii" over to play with your family doesn't hurt sales how will the merest hint of urine hurt a product practically no-one will notice?JonnyDough - Tuesday, August 26, 2008 - link
All the above comments make me wish AnandTech had a rating system on the comments. However, I've found that on sites like Tom's Hardware, the "authors" who never seem to preread their "work" (copying) before posting seem to rate each other up. Then they downrate anyone who opposes them. So I guess it's better if I just sit here and smile and agree in silence. Oops, I've said too much.emboss - Monday, August 25, 2008 - link
You're running the scope way too fast. The switching speeds of most modern PSUs is around 100 KHz, which means you want a timebase of ~10 us, give or take. At 40 ns, you're not going to see anything below a MHz or so, which is almost certainly going to be noise coming from outside the PSU (as opposed to PSU ripple). Also, if you're using AC coupling, make sure the cutoff frequency is well below the 100 KHz mark. One of the scopes I work with has a 250 KHz cutoff (-3 dB) when in AC coupling mode, which would hide any 100 KHz ripple.The main periodic signal in the traces you have is in the order of 100 MHz, and there's no way that's coming from inside the PSU.
Apart from that, good article :)
