FSP Aurum Xilenser AU-500FL 500W

Conclusion

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.
