Teardown & Component Analysis
Before proceeding with this page we strongly encourage you to a look at our PSUs 101 article, which provides valuable information about PSUs and their operation, allowing you to better understand the components we're about to discuss. Our main tools for disassembling PSUs are a Thermaltronics soldering and rework station and a Hakko FR-300 desoldering gun. Finally, for the identification of tiny parts we use an Andonstar HDMI digital microscope.

The TPG-1200F1FAP uses the same platform as Thermaltake's TPI-1200F2FDP. The only differences are the lack of a USB interface, which means you don't get the DPS G App or support for TT's SPM architecture, and the former model's weaker fan.
A $50 price differences separates the two power supplies. We consider that to be pretty significant, given their similar foundation.
Remember: this is a semi-digital platform. Thermaltake states that only the primary side uses digital control. The entire secondary side still employs analog controllers.
The following video footage shows the TPG-1200F1FAP's internals.
