Seasonic X-460FL 460 W Review

Specifications »


We would like to thank Seasonic for supplying the review sample.

Seasonic is one of the most experienced PSU manufacturers out there, since they started manufacturing PSUs quite some time ago. Actually Seasonic entered the PSU market in 1980, to support the legendary Apple II and the first IBM PCs. After two and a half decades and many innovations and significant milestones Seasonic was the first manufacturer that won the 80PLUS efficiency certification, in 2005. Four years later, in 2009, the hi-end X PSU series hits the market and obtains numerous awards and top ratings from every expert PSU reviewer.

The refreshed X series currently counts six members with capacities ranging from 400W to 850W. The two smaller members have a significant difference from the rest, they are totally inaudible since they use only passive cooling. As efficiency goes higher, energy dissipation is minimized so lower cooling capacity is needed and with sophisticated designs the cooling fan can be omitted. Of course in order to completely eliminate the need for active cooling some conditions must be met, with the most significant being the limited capacity of the PSU because the more power a PSU outputs the more its temperature increases. And PSUs are very prone to high temps. So Seasonic decided to go fanless only with the two smaller members of X series, the X-400 and X-460. The latter will be the test subject of this review.
