Are not up by 4 ways, so is the silence you need, you have it in this solid black box. In operation, only this power is completely inaudible, nothing, nada, not a breath. The only reassuring sign of this disturbing silence is the fan running ... and the PC that turns on course. For the rest, its average power is more than enough for a standard configuration or even more if you know that standard choose the components (CPU and GPU) combining power and contained consumption. This exists. It also has a good smoothly (Bronze). In practice, modular power ie it connects only the cables you need for configuration, sheathed cables, a tad stiff but not excessive, and a good solid feel and manufacturing care. Let me be clear, the food is not the only component that can generate noise in a box, it was also the case ventilos the processor and the graphics card. The Be Quite allows you to forget the power supply and take care of others if you have not already done ... To summarize, the average power supply, often more than enough, smoothly good, good build quality, clean assembly and absolute SILENCE. I recommend.
