Seasonic M12II Bronze Evo Edition 850W Power Supply Review

A Closer Look – Interior
The interior of the unit looks nicely designed, with a good amount of space between all the major components, which should help with the overall airflow and cooling of the PSU.
In the corner, we can see there’s a small connector for the fan.
Towards the back, a PCB that holds all the modular cable connectors, behind which you’ll find some more capacitors to help with voltage regulation.
The secondary caps are all high quality, rated for 105c and will help deliver more consistant voltages.
What’s really interesting is that we have a pair of Rubycon 400v 330uf bulk capacitors. More often than not, we see one larger cap, but this should help this unit push some serious power and I’m eager to see how they perform in our testing.
The EM line filtering stage, nicely shielded to prevent electrical interference and ripple.
All of the main hardware and the secondary PCBs are using a vertical design, allowing them to keep heat away from other critical components, while also benefitting from the two heat fin arrays that run the length of the unit to help keep it nice and cool.
Finally, we have an ADDA 120mm DC brushless fan, equipped with 7 large fins that should allow for some decent airflow at low RPM with minimal noise.
