FSP Aurum Xilenser AU-500FL 500W
by Martin Kaffei on April 20, 2012 4:45 AM ESTConclusion
We'd like to make a comparison as always, but we have to wait for more information on pricing and availability first. However, the FSP Aurum Xilenser AU-500-FL offers a good performance and a modular connector panel as well. The worst thing we can say about the performance is that it has higher ripple results than Seasonic (X-460FL) and the electronics could be more silent.
The AU-500FL reached up to 92% efficiency (230V), with no more than 25mV ripple and noise on the smaller outputs and tolerable voltage regulation. There's no fan for cooling, but the electronics made an audible noise this time. Even so the PSU is close to what we'd expect: almost silent. But we should keep in mind that there's some serious competition from Seasonic's product line.
The AU-500FL has four PCIe connectors—quite nice for a passively cooled PSU. All of the cables are longer than 55cm as well, so you can safely use this unit in some larger cases. All the chosen components are upscale and the design and topology is flawless. There is a well equipped filtering behind the entrance and Japanese capacitors are used throughout the PSU (except some all solid caps). The transistors are well dimensioned and FSP offers all the expected safety functions. It should be noted that this PSU looks exactly like a X-460FL without a line filtering stage but multiple +12V outputs.
We definitely look forward to seeing FSP's fanless series in all markets, as passively cooled PSUs are rare. FSP is able to provide a good product that is nearly as good as the solution from Seasonic. In summary, it can be stated that the AU-500FL is recommendable for most PSU enthusiasts if they charge a good price.

I should clarify: sites with referral codes so that you get money from any purchases are clearly spam and will be treated as such. If you link to Newegg for a relevant product and your post has a reason for the link, I'm not going to ban you. But if you have a referral code in there, beware!Iketh - Saturday, April 21, 2012 - link

Mr. Kaffei said: "The AU-500FL has four PCIe connectors—quite nice for a passively cooled PSU".Why should this be a good thing? Who puts 2, 3 or 4 video cards in a system with a passive unit? I'm sure that no one, at least of all the targeted market of this unit. I see other manufacturers make similar moves: Seasonic puts two 6 pin connections in his 460W fanless models. I don't see why?
Perhaps someone care to clarify?

I'm using both 6 pin connections from my seasonic 460w for a 6870... I may not understand your post.My system pulls 220w with prime95 running while playing a game (2600k and 6870) using a mild 3.8ghz overclock. I could throw another 6870 in there and still have 140w of headroom.

What I meant was that who uses a powerful video card does not target absolute silence in a computer and I presume the target market of a such power supply is aiming absolute silence. Otherwise, (like you case) you may be better off with a more powerful PSU, in the same money you buy a Seasonic 460W fanless.Iketh - Saturday, April 21, 2012 - link
That's entirely an incorrect assumption. I do work with my "gaming" rig, and need it as quiet as possible.And I would only increase my power consumption if I went with a more powerful p/s because of efficiencies at certain loads. Most of it would be wasted!

"Who puts 2, 3 or 4 video cards in a system with a passive unit?"Under certain conditions a fanless PSU can be useful. This PSU has high output reserves and is able to power most SLI and CrossFire setups. Please take a look at the following link:
http://www.computerbase.de/artikel/grafikkarten/20...
The hole PC with two GTX 680 needs 432W from power grid. The Seasonic X-Series X-660 in this PC has about 90% efficiency so the DC load is just 388.8W and far below the power rating of this PSU. Image the value setups with cheaper GPUs have. Of course cooling will be a problem and GPUs are usually louder than common PSUs, but some users might be interested in using water cooling for their graphics cards. It's a small target group but they would be quite unhappy without these solutions.
In addition there are more than enough single-chip GPUs with two 6-pin connectors, so two plugs are the minimum for a 400-500W PSU. Another good reason for fanless PSU is that fans are the only moving part in a PSU and very sensitive. Lifetime can be much longer without a fan when installing more powerful components.
Btw. you don't need to use my last name, Martin is enough.

To support Martin's comment:From a silencers point of view it even might be worth a try to team up two passivly cooled cards, even if the number of suited modells may be small.
You might disagree, but that doesn't necessaryly mean your point of view represents all views.

Why the arrow-shaped ventilation holes...? Well, I guess it looks fancy depending on your tastes, but it seems like they would have gotten better airflow out of it by by not making the holes that shape. And isn't that the whole point? Maybe they are hoping the hot air will see the arrows and move out of the case...bryanl - Monday, April 23, 2012 - link
Could you explain this statement in the review?"The overall design definelty looks like a Seasonic X-460FL with different caps and no line filtering stage."
Because I see a line filter in the lower right of the large photo of the interior, attached to the AC socket. If it's not such a filter, what are the differential choke, 2 small disk Y capacitors, and yellow X capacitor?
