Thermaltake Litepower 450W Power Supply Review


Closer Look (The Power Supply):

The Thermaltake Litepower 450W case in unpainted, so all you get is the basic bare metal finish.










Back panel with mains On/Off switch, IEC mains input connector, and exhaust grill. The front panel, with grommeted cable exit port, production test stickers, active PFC sticker, and model/serial number barcode sticker.



One side panel sports a comprehensive specification label, and the other is blank.



Large 120mm cooling fan with chrome grill, and the underside of the power supply.



The only cable that is braided on the Thermaltake Litepower 450W is the main motherboard connector, with the remainder held together by small white cable ties.


The 120mm cooling fan is a Thermaltake TT-1225A (DC Brushless 12V 0.3A), manufactured by Yate Loon.



The printed circuit board is tidy and well laid out. The main large smoothing capacitor is rated at only 85°C, while the remainder are of a more welcome 105°C rating by Teapo. The screen print on the circuit board, FSPXXX-60GHY, indicates the board is manufactured by the FSP Group.



Overall, the build quality of the Thermaltake Litepower 450W is basic, and corners have been cut - but not where it matters. The case is unpainted and cables unbraided, perhaps to cut costs, but the printed circuit board is good quality by a reputable manufacturer. Packaging and accessories are basic but adequate, but is the price low enough to reflect this? More about this later. Let's see how well it performs.
