Seasonic are launching a new range of power supplies in the coming weeks and today we look at the 850W model in the Evo Edition series. The M12 II Bronze Evo Edition 850W is a full modular design achieving 80 Plus Bronze certification. 

Seasonic are releasing only two models in this series (750W and 850W) with stock due to land in the United Kingdom very soon. Seasonic are not compromising in regards to component selection, the design is a double forward converter implementation. They are also incorporating high grade Japanese components inside and we will take a closer look at this later in the review.

The Seasonic M12II Bronze Evo Edition is an updated version of past models and has full support for the latest Intel Haswell Z87 platform.

We recently published a little article on these compatibility concerns over here, with a short excerpt below:

“Intel’s Haswell C6/C7 power states require a minimum load of 0.05A on the 12V2 rail and many current power supplies will fail to provide that low a current. Many older power supply designs comply with ATX 12V V2.3 design guidelines meaning they only call for load of 0.5A on the CPU power rail. This will mean C6 and C7 power states will be disabled in the bios.

There may be cases that the supplies will become unstable when the processors try to enter into these states. Additionally the problems get worse when we factor in that many power supply units do not report minimum currents supported by the 12V2 rail.

The problem may kick in when the CPU enters sleep mode but with a load on the power supply non primary +3.3V and +5V rails. If the load on these rails hits a certain point (different from PSU to PSU) the +12V can go out of spec – voltages greater than 12.6V. If the +12V is out of spec when the system steps out of sleep state the power supply protection may kick in and stop the power supply from running normally. This situation may involve the end user turning the power supply switch off and back on again.

A power supply that uses a DC to DC design for the non primary +3.3V and +5V rails will not have a problem with the new low power sleep states. The reason is based around the DC to DC converter, used to convert +12V to +3.3V and +5V. This design ensures that there will always be load on the +12V regards of the load the CPU places on the power supply.”
