Under the Hood

Thermaltake uses a large 140mm ARGB fan for cooling. It uses a 2-wire cable for 12V power and a 3-wire cable for the RGB system.

Both RGB side panels are daisy-chained together.

The power supply mainboard is very densely packed.

Incoming AC power is heavily filtered as it comes into the unit.

Main filter caps are Japanese Nichicon 105C rated caps that should provide a long and stable life.

This is a rather unusual sight in the power supply world. Thermaltake uses quite a few plastic-clad copper sheets for shielding.

There is a ton of filtering and shielding even on the DC output side of the power supply.

The entire DC output side runs with heavy bus bars rather than wires like lesser units. We also see that the same daughterboard is used on the largest 1200W unit, but with a few plugs missing.

Even the casing has the same missing plug spots but is covered with a sticker from the outside.

Looking a little closer, the mainboard also has the CST 1200 markings. It appears Thermaltake is using the same physical platform for all units in this lineup.

The solder job looks great on the bottom of the PCB and, rather amusingly, uses a green solder mask since it cant be seen.
