Another good platform from FSP, which confirms that they are trying to establish a permanent position in the champions league of PSU manufacturers. In a recent review I had the chance to take a look at their fresh design which Be Quiet utilized in the new Dark Pro Series P10 550W unit and I admit that I was left very satisfied by FSP's (and Be Quiet's) implementation. Today the new Aurum Xilenser 500W sported an equally good performance with even lower ripple at +12V, although at 5V ripple suppression was average; but after all this is a minor rail with minimal significance compared to +12V.
Surely the strongest point of the new Xilenser is reflected in its passive cooling which leads to minimal noise output. This is the cherry on top for users that hate noisy components and seek for the quietest possible PSU for their systems. If you also take into account the tight voltage regulation, the four PCIe connectors, the good overall built quality and the flat modular cables which may not be highly flexible but still greatly help in increasing the airflow inside the case, then you have a pretty strong pack of features that renders the new AU-500FL a very good PSU.

To sum up, the relatively high ripple on the 5V rail and the lack of OTP cannot spoil the good impression that Xilenser 500W made. This PSU provided very good overall results, has a unique look and it is almost fully modular since only the 24pin ATX cable is fixed. If FSP manages to offer it at a fair price, although fanless PSUs tend to be expensive, then it will be very competitive and a good choice for users who want a fanless PSU for their system. However I think that the current MSRP is way too high and this is the only reason that I didn't give it our Recommended award.
