On the Inside
Next, we’ll take a quick peek under the hood of the Enermax Platimax D.F. 1200W.
The 139mm fan used in the Platimax D.F. 1200W is the ED142512H-FA rated at nearly 6W.
Power input is via these locking quick-disconnect terminals. It makes disassembly and reassembly a snap to take some teardown pictures, but they do take some effort to disconnect so don’t worry about loose connections down the road.
The initial stage of filtering comprised of 1 X-cap and 2 Y-caps takes place right at the socket. The DFR switch is just on the other side of the rear.
Four more Y-caps and another X-cap plus a pair of chokes are found on the main PCB along with a fuse.
A pair of full wave bridge rectifiers provides the initial conversion to DC which is filtered with two large NCC 470uF caps.
The modular connectors are interleaved with heavy buss bars and lots of extra filtering capacitors for the cleanest power possible right up to the very start of the cables.
The soldering job looks clean and effective.
Even the daughter boards have components connected to heat sinks.
The overall layout is very dense and requires the use of multiple daughter boards to achieve the rather small footprint.
