The Focus series from Seasonic represents a long-awaited re-entry into the power supply market and includes compact 80 PLUS Gold-rated models with fully modular cable management that also looks stylish while operating quietly thanks to the quiet and reliable semi-passive 120 mm fan. The smart choice of components, included so as to complement one another during operation, as well as the materials used all meet the high standards of Seasonic and the end result is a premium product with a 10 year guarantee that demonstrates Seasonic\'s confidence in their power supplies. The Seasonic Focus GX Gold Power Supply at a Glance:550 Watt power supply with powerful 45A single railHigh efficiency with 80 PLUS Gold certificationQuiet 120 mm fan with semi-passive modeFully modular cable management with flat cablesFour 6+2-pin PCIe connectors for graphics cardsPower Supply with 80 PLUS Gold Efficiency and Powerful 62A Single RailThe Seasonic Focus GX Gold supplies up to 550 Watts in total output, meaning that even high-end PCs will be powered with ease. The powerful 12 Volt rail also delivers a full 45A output. In spite of these impressive specifications, the Seasonic Focus PX Platinum is created with efficiency in mind as well, and this could only happen when Seasonic opts for the highest quality components - such as the capacitors for example. Consequently, the power supply received an 80 PLUS Platinum certification, meaning that it is capable of 90% efficiency under a 50% load. In terms of tidiness, Seasonic smartly opted to make their power supply cables fully modular - arguably a must with the amount of connectivity options on offer! Besides a 24-Pin- and two 4+4-pin cables, the PSU includes (among other things), four 6+2-pin PCIe connectors as well as eight SATA- and three 4-pin Molex connectors. The cables are very flat and easy to cable manage. The included 120 mm fan provides, thanks in large part to its quiet-running Fluid Dynamic Bearings, very low noise during operation. The added benefit of FDB is the fact that they also happen to be incredibly robust and durable. A switch on the back of the power supply allows users to choose between automatic fan regulation either with or without a passive mode. Depending on how hard the power supply is being pushed, users will benefit from reduced noise levels or maximised cooling performance respectively. It almost goes without saying that the Seasonic Focus GX Gold naturally includes all the safety features we have come to expect from modern power supplies. Should the PSU fail unexpectedly, not to worry - Seasonic stands behind this exceptional product with a full ten-year manufacturer\'s guarantee!
