Quality power supply: Cheap but fair.
Came with a neat little bag to put unused cables and tools in, alongside its additional screws

★★★★★Its a PC power supply

Its a power supply, I like the fact that it is modular so you do not have a mass of cables to hide. the cables aren't the prettiest with the exception of the braided 5.1 cable.
