Internals

Opening the PSU requires loosening six hex screws. The fan alongside the grill is also held in place by hex screws albeit of a slightly different size.

As we open the casing we see an overall not too packed layout. From the markings on the PCB it looks like the same board is used across the full Titan Gold range from the 750 W right up to the most powerful 1200 W unit. MONTECH (or we should say CWT) uses a half-bridge resonant LLC topology for this unit. In fact, it is the same platform used in the NZXT C1200 unit.


On the AC filtering side we find two Y and one X capacitor soldered right on the back of the AC plug. Two additional Y and one X cap can be found right at the corner of the PCB below, alongside two chokes and an MOV. There's no lack of thermal interface material to help in transferring the heat from the bridge rectifiers to the heatsink.


For bulk capacitors, instead of one larger unit, two 470 uF / 420 V Nichicon capacitors have been chosen to operate in parallel.


The connector board is quite busy with almost all space used up by connectors and some solid state capacitors. At the top there's one lonely electrolytic capacitor from Nichicon.


Right behind the main transformer and the board with MOSFETs to regulate the +12V rail, we have the DC-DC converter board to deliver the +3.3V and +5V rail output.


At the back of the PCB we can see no issues with the soldering quality. Here we can also find the Champion CU6901VAC resonant controller.

As Montech specifies in their website, the Titan Gold line indeed features all Japanese capacitors. Some are Nichicons (like the two main bulk capacitors), Nippon Chemicons (KZE and KYA series) and there are some Rubycons as well.


The MONTECH Titan Gold 1000 W utilizes a 135 mm HA13525H12SF-Z fan (12 V, 0.5 A, up to 2300 RPM) with seven blades. It is partially covered with a plastic cover for better airflow direction. We have already seen that exact fan model with a previous unit. So even though an 80 Plus Gold unit is expected to produce slightly more heat than an 80 Plus Platinum one, the expectations of acoustic performance are still quite high.
