In a nutshell:
[quote]FINAL CONCLUSIONS
That the Seasonic X-400 Fanless would excel in this roundup was a forgone conclusion. Our full review last week showed that the X-400 Fanless passed our torture hotbox test at 400W for 15 hours without any problems whatsoever. It seems able to run indefinitely at full rated power with minimal airflow (at ~24°C room temperature). Efficiency and electrical performance is top notch. The X-400 is an SPCR Editor’s Choice product and our #1 recommendation among fanless PSUs. Add totally modular cables and a 5-year warranty, and the $140 MSRP looks like good value in this roundup.
