Seasonic M12II Bronze Evo Edition 850W Power Supply Review

Introduction & Packaging

Seasonic is one of the biggest power supply manufacturers in the world, creating many of the best performing units available on the market today, so we’re very happy to see their new M12II Bronze Evo Edition 850W unit on our test bench today. We’ve seen a lot of Seasonic power supplies over the year and featured many of them in our own personal builds too, as time and time again they’ve proven they can deliver great looking units, with solid performance and features every single time, so we have high expectations of this unit we’re testing today.

Equipped with all the latest safety features that we’ve come to expect, as well as a wide range of connectors to suit virtually any system build, fully modular flat cables, and Bronze level efficiency, we’re ticking all the right boxes for a mid-budget, high-wattage PSU. So let’s get right to it and take a closer look at what it has to offer.

The packaging is nicely designed, with a clear image of the PSU as well as details of all the major specifications; 850W, ATX12V, 80 Plus Bronze, SLI support.

Around the back, a more detailed run down of the specifications and features, but let’s open the box and see for ourselves.

In the box, you’ll find the usual user’s manual, fitting screws and a protective bag with all the required cables.
