MANUFACTURER Seasonic

The Focus series from Seasonic represents a long-awaited reentry into the power supply market and includes compact 80 PLUS Platinum-rated models with fully modular cable management that also looks stylish while operating quietly thanks to a semi-passive 120 mm fan. The smart choice of components, included so as to complement one another during operation, as wel 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 PX Platinum Power Supply at a Glance:

  • 850 Watt PSU with powerful 70 A single rail
  • High efficiency with 80 PLUS Platinum certification
  • Quiet 120 mm fan with semi-passive mode
  • Fully modular cable management with flat cables
  • Six 6+2-Pin PCIe connectors for graphics cards

80 PLUS Platinum Efficiency Power Supply with Powerful 70A Single Rail

The Seasonic Focus PX Platinum supplies up to 850 Watts of power, meaning that even high-end PCs will be powered with ease. The powerful 12 Volt rail also delivers a full 70A 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 cable 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 one 24-pin- and two 4+4-pin cables, the PSU includes (among other things) six 6+2-Pin PCIe connectors as well as ten SATA- and five 4-pin Molex connectors. The cables have a flat design to make cable management as straightforward as possible.

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 PX Platinum 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!
