In The Box


IN WIN Commander 1200 Modular Power Supply


Given the naming scheme of this product, it is no real surprise to see a military style packaging and appearance. With the camouflage coloring on the box to the olive drab paint on the power supply itself, it fits right in with the Commander moniker. For those concerned with this color, however, it is dark enough to be unobtrusive in an enclosure with a window. If a black colored PSU will fit your color scheme, then this one will also fit in with no issues.


As for what you actually get, there isn't a lot of extra stuff, but there is plenty for the task at hand. Besides the main unit you get a package of the modular cabling strings, a power cord, the mounting screws and a few zip ties to help you with your cable management. Also included are a protective bag for the main unit and a nylon portfolio-type casing for the extra cables.

The main unit itself, as noted earlier, is of a modular design. As we have pointed out before, this is a great feature for those who are concerned about cable management since you only attach the strings containing the connectivity options you need. The others remain stored away and you don't have to worry about keeping them out of the line of the main airflow. Just one of those things that isn't really necessary, but is certainly nice to see.


As far as power is concerned, the Commander 1200 is rated at 1200 watts of continuous power draw. The unit has four 12v rails with two being rated at 20A each and two being rated at 36A each. This gives plenty of overhead for high-end graphics solutions, but even if you need more power along the 12v rail, the Commander is an auto-switching model meaning that the 12v rails will combine if one becomes overloaded. Both the 5v and 3.3v rails are rated at 30A each giving a lot of system flexibility.

The external facing of the Commander 1200 is rather plain in appearance, consisting of nothing more than a power port and a toggle switch that allows you to turn the power supply on and off. The remaining space is taken up by a mesh facing that allows ample air to be circulated through the unit. For those concerned about lighting effects, there is a light red glow that comes from the toggle switch. Keep in mind that this will be facing outward, so will not interfere with any lighting you may already have in place.

To keep the air moving through this beast of a power supply, IN WIN uses a large 140mm fan in the bottom face of the unit. This allows for a lot of air to be moved through the enclosure with a minimal amount of noise. Like most power supplies currently available, it has a thermistor installed internally that allows the fan to automatically adjust in speed to combat excessive heat. During our tests, I was never able to hear the fan of the power supply. It is nice and quiet but works well to keep your PSU from overheating.


It should also be noted that there is no LED lighting in this fan so it will not interfere with colored schemes you may already have installed. Just my opinion, but this is in keeping with the militaristic theme of the PSU; no lighting to give away its position.

As noted earlier, this is a modular model with only a few native connections actually coming from the internals of the power supply enclosure. Native cabling includes a 20+4 pin primary, an 8-pin (EPS) connector and a 4+4 pin (ATX) connector. These cables are cinched together as they exit the housing, then are wrapped in a mesh material to keep your air channels as open as possible.


The remaining power needs are modular and will be attached to this internal panel. The red and blue ports you see above are color coded for the graphics subsystem and are designed to help you keep from drawing too much power from a single rail. The four ports to the left are for your other cable assemblies and can be set up in whatever manner you desire. To keep dust from clogging the unused ports, plastic covers are inserted into all the openings. Just remove the ones you need for your system and leave the remaining ones in the unit.

As far as cabling is concerned, there are many to choose from. Modular cable assemblies include 3x PCI-E6, 3x PCI-E6+2, 10x SATA, 8x Molex and 2x FDD. The SATA connections are set up on two strings of 5 connectors each with the shortest length to connector measured at 21" and the longest distance measured at 46". The Molex and FDD connectors are set up on two strings in a 4x1 configuration (four Molex and one FDD per string). Minimum length for the Molex strings was measured at 20.5" and maximum length was measured at 38". The FDD connectors are at the end of each string and measure in at 44".

A final note regarding the modular cabling concerns the Molex connectors. Though this feature is not as uncommon as it once was, I always like to see the Molex mod as shown above. It is a simple concept, but can make things a lot easier when you need to disengage a Molex. The connector is inserted in a normal manner. When you need to remove it for any reason, simply pinch the plastic tabs and it causes the Molex to easily come out of the peripheral. Nothing really fancy, but it is a nice feature and is incredibly handy for those (like me) who are constantly changing out components.


Now that we have had a chance to see what we get for our money, let's see how well this thing performs!
