80 PLUS Platinum
The higher the level of efficiency of the power supply, the less power gets wasted in the form of excess heat. The 80 PLUS Platinum certification provides greater than 90, 92, and 89% efficiency at 20, 50, and 100% operating loads, respectively.
Compact Design
This densely packed power supply features a small footprint of 5.5" (140mm), making it suitable for compact ATX cases.
Fluid Dynamic Fan Bearing
Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its durable construction, this reliable fan technology also increases the lifespan of the fan.
Hybrid Silent Fan Control
Seasonic's three-phased thermal control provides optimal silence and cooling. This Hybrid Silent Fan Control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling Mode. Benefits of this design include reduced noise, extended fan life, optimized heat dissipation, and silent performance in fanless mode. Additionally, there is a switch at the back of the power supply that allows you to customize cooling by selecting between the Seasonic S2FC (fan control without Fanless Mode) and the S3FC (fan control including Fanless Mode).
Additional Features
The FOCUS Plus power supply is designed with a tight voltage regulation, which reduces voltage variations, to provide smooth and stable operations. Moreover, the back panel and PCB are connected by a copper plate instead of cables to lower the chance of production errors and improve power output quality.

Incredibly well-designed modular interface with all the cables one could reasonably need (for anything that uses =750W)

Running this in a new build, came with plenty of cables and connectors for everything I needed. Plenty of length on cables, solid packaging, runs quiet and efficient... Couldn't ask for more.

Not sexy, but perfect

Has all the included modular cables and accessories needed. And the included loopback tester is a nice touch. Everything worked as advertised and powered up my system on the first try. Now feel confident in any power needs now and with future upgrades.

These are great power supplies. I've always used quality power supplies and these rank right up there with Corsair.

Easy to work with and quiet

For my needs has enough capacity for power, and included enough CPU headers to cover a 8 4 configuration. The wrapped ATX cable was nice for cable management. Cables were long enough to route to the needed places without issue. The power supply includes a self tester, which was a nice check before setting it up more fully. It has a hybrid mode (where the fan can shut off) but the fan itself is somewhat quiet, nothing distracting. This went into a 5900x / single GPU build.
