Sounds impressive, but can Enermax deliver this spectacular sounding product with no coil whine and that doesn't cost as much as a kidney.http://www.tomshardware.co.uk/Enermax-S ... 42997.html
The coil whine should not be an issue at all due to Enermax being a quality manufacturer, I believe its usually the high voltage stuff that creates the whine but I am sure that the DC-DC circuitry wont hurt in the regards of coil whine and other nasty high pitched non-coil noises.
As for the Platinum rating, that sounds very impressive indeed but most people here will be as interested in its low wattage efficiency as its maximum efficiency at 400w (or wherever it hits its claimed 94%).
As for silent/quiet gamers, this is probably not quite as interesting a product as non-gamers might assume, if only for one reason, fans..... CPU and GPU fans nearly always ramp up inside gaming machines, and gamers (like me) don't really care as there are speakers or headphones turned on anyway, and if those gamers are as diligent as I am with product selection, the noise increase whilst gaming from CPU and GPU fans is not that much anyway over idle fan noises, so this silent PSU will likely not make any real-world noise difference over a good quality PSU in a good case anyway.
Personally I have not once noticed my PSU fan speed increasing whilst playing games (PC specs below), and due to my case having a seperate enclosure for drives and the PSU with no other fan, I would personally have to add a fan to stop my drives and this PSU from cooking themselves (or each other).
The single best thing I can see about this PSU personally is that it is pushing boundaries of just what is possible with modern PC PSU's, and that is very good news for us consumers.
