FSP are using a Protechnic Electric fan, model number MGA13512XF-A25 rated 12V 0.38A. This is a high quality 135mm Fluid Dynamic bearing fan we have seen in other power supplies before such as the Hydro Ti Pro series. There is a plastic panel affixed to the fan which helps direct airflow across specific parts of the PCB and components underneath.
Protechnic Electric make some pretty good fans based on my years of reviewing power supplies, but I do not see them used that often in many units anymore, for some reason.
As mentioned earlier FSP make their own designs – the Mega TI is no different. Some of these designs can often be tweaked visually or technically for various partners such as ASRock. FSP are using a high grade topology in this unit, comprising full bridge & LLC converter with a synchronous rectifier with DC to DC converters to generate the minor rails.
This is a very densely packed PCB. Due to the claimed efficiency there is no need to populate the internal layout with massive heatsinks. FSP have adopted several vertical daughter-cards in various parts of the PCB to help reduce the space demand.
Soldering quality inside is really extremely good with a lot of attention to detail throughout. And I was happy to see high grade Japanese caps used in both primary and secondary stages. In the primary stage FSP have used Nippon Chemi Con 105c rated Japanese caps rated 450v 560uF x3, for a total of 1680uF output.
The unit offers OCP, OVP, SCP, OPP, UVP and OTP protections.
