FSP Aurum Xilenser 400W Power Supply

I’ve had a few fanless units come in here now and again and attempt to impress me. Some have succeeded more than others. FSP is the latest company to send one of these silent marvels my way, and they’re looking to find out what I think of it. Coming in at 400 watts, this is a fully hardwired unit that promises 80 Plus Gold efficiency.

FSP Aurum Xilenser 400W

Back in June, I snuck down south to help Tony and his dog Izzy review a large Fortron-Source Power unit in the Aurum Pro 1kW. It turned out to be quite a decent performer, garnering itself a recommendation at the end of the review. FSP was encouraged by this, and asked if I would be willing to have a peek at something else new they were putting together.

As you can see above, that “something” turned out to be the Aurum Xilenser 400 watt fanless unit, certified as 80 Plus Gold.

Xilenser. Ok then. Xeems a little xilly, that name. Especially xince they draw attention to the way “silence” is xupposed to be xpelled with a C right underneath the product name. Well, we’re just going to have to xee how thix unit performx before we call it xilly or not. Xeriouxly, I’m going to run it through its pacex and we’ll find out what it can do.

As usual, there’s some marketing on the box to show you. I’ll reprint some of it here for you:

AURUM Xilenser Series. 100% Perfect Zero Noise – Absolute 0dB
AURUM Xilenser is 80PLUS GOLD certified with over 90% efficiency, continuing FSP’s unique commitment to energy efficiency with more 80PLUS certified power supplies than any other manufacturer. The high efficiency and superior passive cooling maintains a low PSU temperature – even under pressure. It is the perfect combination of premium quality and efficiency, making it the ideal choice for those who seek state of the art performance with zero noise. The completely silent and fanless operation makes it the perfect solution for your Home Theatre PC (HTPC), lab, and studio environment.
This is actually a bit of a dubious claim, as fanless units do not necessarily mean they are noise free. The reality is, any time you’re converting AC to DC, there’s always the chance that the electronics themselves will make some quiet noises, fan or no fan. That said, I do not have a way to validate this claim, so I’ll give them the benefit of the doubt here.

Unique Airflow Technology for regulated outward airflow
Arrow shaped ventilation makes use of Aero Dynamics and Physical properties of hot air to improve and speed up hot air extraction.
Ah, good. I study Aero Dynamics often. I go to the convenience store, buy an Aero bar, and study the dynamics of how fast I can get one out of the wrapper and down my throat.

100% Japanese Capacitor
Long life Industrial Grade Capacitor: 105°C Japanese-made top quality capacitor for prolonged lifespan.
We’ll see about that when we get inside the unit.

Active PFC
Power factor ‰¥ 99%

Full Safety Approved
Let OVP/UVP/OCP/SCP/OPP protect you and your system.
Yes… let the Ontario Provincial Police protect you and your system.

S.B. Ready
Supports Intel latest platform.
I’ll wager it supports latest AMD platform too.

There are also a list of features printed on here, but since they’re all repeats of what I just typed out for you I won’t bother with them.

From this side of the box, we can see that we are in fact dealing with a fanless power supply unit from FSP here.

This side of the box tells you all about how to find FSP’s website.

Finally, if we want any more information about this unit, we are directed to the website. Since I couldn’t find any temp specs on full power operation, I did in fact go to the website. Which did not have them, either. I’ll just shoot for 40 degrees in the hot box – that ought to do it.

OK, I WILL!

Inside the box, I found one of those power supply thingers, a user guide, power cord, a sticker, some velcro cable ties, and some black knurled screws.

Here’s the manual, again lacking in any temp specs for full power operation.

I didn’t like the way the Aurum Pro looked. I felt it was tacky and ugly in appearance. This unit is still a touch on the ugly side for me, just because those tan accents are made of really cheap looking plastic, but it does look a bit better than the Aurum Pro did.

Another angle. This is not the modular version of this fanless unit, so we have no modular connectors to talk about.

The arrows do look kind of cool, but I don’t really know if they do more than normal ventilation holes to make the unit be cool.

FSP Aurum Xilenser 400W

There are openings for ventilation on all sides of this unit.

FSP Aurum Xilenser 400W

See? Told you so.

I would have preferred a slightly more complete sleeving job than this, but it’s not bad as is. I just like to see the sleeving go right inside the box, is all.

FSP Aurum Xilenser 400W

This is normally when we look at the fan, but instead we’re looking at a big ventilation grille instead.

The label gives us a handy guide as to which connectors are on which 12V rail, I see. I also see that it’s a bit non-standard, so I may have trouble testing this unit as a dual 12V unit. I’ll deal with that on the next page.

Here are all the cables, splayed out for your viewing enjoyment. As a rule, I tend to think of fully hardwired units as yesterday’s news. Yeah, doing it this way saves the cost of those extra modular connectors, but really – it’s 2012. Modularity is everywhere, and very much preferred on any unit I run in my own systems.

Yes indeed, the 12V rail distribution is odd on this guy. The modular CPU connector is split between the two, effectively bridging the two together should you plug it into an 8 pin motherboard connector. That might actually not be a bad idea… turning this unit into a single 40A 12V design via that connector may prevent some shutdown issues on rigs that require an 8 pin connector, depending on where the overcurrent protection trip point is.
