Examination:

The very first thing that we check on power supplies is the weight. As mentioned many times before, weight is one of the best indicators of a power supply's quality. So far, most heavy power supplies have performed very well. Light power supplies are the ones that are unstable and fail. As far as we have seen, there are very few exceptions. This unit is pretty heavy, but probably considered light in the 6XX Watt range. However we aren't too worried, since it still feels very solid.

The unit is coated with a black metallic paint. It's not a Jet-black coat as many units have however. The paint is speckled with some sort of shiny silver material. In any case, it does look very nice. On the bottom of the unit there is a 120mm fan. The gold fan grill covering the fan proudly carries and imprinted Enermax label. As with many units these days, instead of having an exhaust fan at the back, Enermax has used a mesh grill. This allows for very good airflow, and also eliminates the extra noise of an additional fan. On the other side of the unit there are connectors for six peripheral modular cables. These connectors are color coded black. The dark red sockets are dedicated to PCI-E modular cables. The Liberty features a 20+4-pin motherboard connector. This type of connector has become popular amongst power supply manufacturers, and is very convenient. The connector eliminates the need for adapters when using older 20-pin boards. They have also included a very convenient 4+4-pin CPU +12V power connector.

Some of the more recent motherboards (such as DFI's latest SLI-DR Expert) and BTX solutions use the 8-pin connector. The inclusion of the 20+4-pin and 4+4-pin power connectors allows the Liberty to be used on virtually any current system. Aside from these two connectors, Enermax also included six sets of Eternity pair connectors. These connectors each feature two SATA power connectors and two 4-pin molex connectors. Two of the six connectors also include floppy connectors. These are very convenient, and a very innovative feature. Of course now that we finished checking out the outside of the unit, let's crack this thing open and take a look under the hood. As has been repeated many times, opening up this unit means that you void your warranty, so don't do this at home. The unit is very neatly laid out inside. Everything is very cleanly put together.
