The Cooler Master MasterWatt Maker 1200 arrives in a huge box which features an artistic representation of the unit at the side. The box weighs 5.35kg. The box also proudly displays the Red Dot Design award logo. This is an 80 Plus Titanium certified power supply, as indicated by the logo bottom right at the front of the box.

A yellow sticker explains the use of the BlueTooth module. You do not remove the Bluetooth module during operation, or it can cause the power supply to shut down.

With the BlueTooth module installed you are able to control aspects of the power supply from your mobile phone. The application is available on the Google Store and the Apple App Store.

Cooler Master have developed a software package available for desktop Windows based PC’s and for iOS and Android mobile devices. The power supply will communicate with the system via a USB cable or BlueTooth 3.0 connection via the supplied dongle.

Most of the interesting settings are available via the POWER menu on the first page. The design is fine and fairly intuitive to follow. The overview tab details the thermal setup, input and output and rough cost calculations. The monitoring section allows the user to check PSU status.

The modes window is the most important as you can change profiles to load one of five modes. You are also allowed to disable OCP on the +12V rail.

Cooler Master include a regional specific power cable (c19 heavy duty power cord which can handle up to 16A), cable ties, mounting screws and a nice little felt storage pouch. They also include a lot of literature with the product, including a handy little user manual. I was quite surprised that Cooler Master didn’t include a little branded case badge as often seen in flagship products of competitors.

The power supply is well protected inside a soft bag, shown above. The box does offer plenty of protection for the unit itself, which is reassuring to see.

The cables are a mixture of 16 AWG (EPS and PCIe) and 18 AWG and all are flat ribbon style for ease of routing inside a system chassis. This 1200w unit has a total of 10 PCIe connectors, which offers plenty of support for both high end SLi and Crossfire systems. There are 16 SATA connectors and 12 peripheral connectors available as well.

Cooler Master claim these connectors via the larger pins on the modular bay can deliver 150% more current than on a standard power supply.

The Cooler Master MasterWatt Maker 1200 can switch between single and Multi (Dual) rail with the Cooler Master Connect software. The default setting is dual rail. The Pin/Connector layout per rail is shown in the image above.
