The Commander power supply is cooled by a single 140mm fan, not the typical 120mm we see in most performance supplies. Although we aren't given much info on it, they do state that it's a silent double ball bearing fan. This fan is thermally controlled so it should be pretty quiet in operation because we all know that the bigger the fan, the more airflow it produces. Therefore, a big fan spinning slower will produce the same amount of airflow as a smaller fan spinning faster (and louder). The fan is black with flat-black fan grill that blends really nicely into the "army" feel of the power supply's design.

Spinning around to the back side where the modular connectors are located shows yet another indication of the attention to detail put into the design of this power supply. The modular cable connectors on the power supply are grouped according to the type of device they power. Under each grouping are a few small painted boxes with pictures labelling the type of cables used with those connectors. Each connector has a rubber cover that inserts into it to protect them from dust and stray screwdrivers (that shouldn't be inside a running computer). I was impressed to see that even these little rubber covers had small raised squares to hold onto while pulling them off - wow! The only hard wired cable on the entire power supply is the single 20+4 pin ATX connector. All other modular cable layouts are described below.

1x ATX 20+4 pin motherboard connector
1x 4+4 Pin ATX/EPS +12V connector
7x 4-pin Molex connectors
6x SATA connectors
1x FDD connector
4x 6+2 Pin PCI-E connectors

To get a little more technical now, the Commander series of power supplies all carry the 80PLUS certification logo. This means they have passed stringent testing and will perform at 80% or greater efficiency. For you, this means less power wasted; you can call it your contribution to a greener tomorrow. All power supplies in the series also use Active PFC (Power Factor Correction). To put this into simple terms, this helps with providing a more efficient power frequency. Active PFC is much more superior to Passive PFC when building a high quality power supply although it is slightly more costly to impliment because it relys on an entire circuit instead of just a filter on the AC input. Protection measures on this power supply are the standard over voltage protection, over current protection, over power protection, under voltage protection and short circuit protection.

Before I move onto the other portions of this review I'd also like to state that InWin provides a full 3 year warranty on this line of power supplies. With most power supplies ranging in the one to two year warranty range, it's great to see a company confident enough in their product to stand behind it a little longer.
