Cooler Master V1200 Platinum Power Supply Review


ACC_6470_DxO
The Cooler Master V1200 Platinum power supply is using a Protechnic fan, marked MGA12512XF-o25. Cooler Master have used the same fan before – we have seen it used in some of their high end power supplies in the past, such as the V Series 1000W. This is a fluid Dynamic Bearing fan which will have a much longer life span than a standard ball bearing cooling fan. This fan should last a very long time indeed.

This is a Seasonic XP3 design and the build is very clean. The soldering quality throughout is exceptional.

Behind the AC receptable is a sealed PCB which is home to some of the components of the EMI filter – a single X cap, four Y caps and a CM choke. The other components of the filtering stage are on the main PCB, which include an MOV, two pairs of Y and X Caps and two more CM chokes.

The primary side is a full bridge design with an LLC converter for lossless switching. The secondary side uses a synchronous design with +12V fets on the main PCB. The DC-DC converters are installed on the modular PCB to help reduce power loss.

The main PCB and modular PCB incorporate high grade Japanese electrolytic and solid capacitors.
