The dual-fan design coupled with an efficiency rating above 80% under any load, allow for ultra-quiet operation for use in home or office environments. Overclockers may benefit from the 3% voltage tolerance on the +12 V power line (compared to the standard 5%) thanks to the dual magnetic amplifiers (Mag-Amp)
Normally, dual-fan power supplies aren't very quiet but Seasonic makes provisions to ensure a power supply that is as quiet as possible. The M12 power supply has soft cushion to help insulate fan vibration from your computer case. Also, it includes 12 cm and 6 cm ball-bearing fans to help further reduce vibration and, subsequently, noise.
New to the M12 series is the inclusion of cable sleeves to help keep your cabling tidy. Look for this PSU somewhere in the range of ~$200-$220.
