Specifications

The specifications for the Litepower 450 as listed on Thermaltake's website are as follows:


You'll note that the Litepower 450W is rated for a very respectable 85% efficiency, which places it in the 80 Plus Bronze classification as specified by the 80plus.org energy organization. In order to be considered for an 80 Plus certification, the power supply must meet a minimum of 80% efficiency across the board. Bronze, Silver and Gold ratings go above and beyond the standard 80 Plus certification by requiring higher levels of efficiency. To meet the Bronze level, the power supply must perform above 82/85/82% efficiency at 20/50/100% load rating. From this we can determine that the Litepower 450W meets its 85% efficiency at a 50% load, or roughly around 225W of output. Another feature of the Litepower to be noted is the impressive five year warranty offered by Thermaltake.


Inside the Litepower 450W box we find a relatively plain-looking power supply. Indeed the painted gray steel case and unsleeved power cables are more indicative of low-end units typically associated with OEM or off-brand power supplies, the kind you might get for free with that case you bought at the computer show. But we mustn't judge a book by its cover, and as we pull the Litepower 450W out of the box and flip it over we find it has some features more often associated with a high quality power supply, such as the large 120mm fan, open mesh rear vent and a nice amount of heft to the unit. While weight alone doesn't guarantee the quality of a power supply, it is often a good indicator as to the level of components and construction used.


In addition to the on/off rocker switch found on the rear of the power supply we can also determine that the Litepower 450W has an auto-sensing 110/240V operating range. The label on the side indicates it is model number LP-450AH2NF power supply with output specifications that match Thermaltake's advertised numbers. The UL identification number E190414, indicates that this particular unit is manufactured by FSP Group, a well-known OEM manufacturer of high quality power supplies. The UL ID can be verified using their online database lookup.
