Under the Hood
Here are a few pictures showing the layout and components inside the Toughpower Grand 1200W power supply. Thermaltake appears to be using Sirfa instead of CWT as the OEM for the Grand series.
The two primary capacitors are made by Nippon Chemi-Con and rated for 560uF, 400V and 105°C with a combination of solid polymer and electrolytic caps also made by Nippon Chemi-Con populating the secondary side.
The overall layout, build quality and component selection looks good; nothing bad but nothing exceptional either.
