Internals

The inside is long… very long. We haven't seen such a long power supply since our time with the Enermax Galaxy. The heatsinks are very small and there are no fins cut out from the aluminum block. This leaves much room for the air to travel through directly the PCB and cooling everything openly placed. This is actually a very nice setup and it looks pretty clean. Most of the heat is transferred to the front with the installed heatpipes. There is no doubt that this unit is actually made by Enhance, who delivers one of the best power supply designs at the moment.

The filtering stage is well built and goes from the top over the right corner to the upper right side. The two rectifier bridges carry a funny looking heatsink, resembling a TV antenna from the old days. The two main-caps are made by Matsushita (Panasonic) and rated at 420V and 270µF. There are two main transformers and a small one for the 5Vsb circuit. The secondary capacitors are made by Teapo, a common friend nowadays in power supplies. There are two thermal sensors on the right and left side of the secondary heatsink which are connected to the fan control.
