Pros: Sweet Silence, modular, platinum efficiency. 600 watts fits my needs... I just swapped out an older enermax for this power supply in a Fractal Design Define R4 case. The power supply design is semi passive so the fan does not start turning until 50% of the supplies rating. I don't know if its spinning as I type this but i dare say my system is finally silent. (ps-also using a passive video card)

Cons: i read a french review and they said the packaging was excessive. i kind of have to agree but nice to have anyway.
