CyberPower Achilles Pro System review (i5 4690/GTX780)

Ambient noise in the room is around 20-25dBa. We measure from a distance of around 1,5 meters from the closed chassis and 4 foot from the ground to mirror a real world situation.

We use a calibrated meter.

noise
The CyberPower Achilles Pro is a very quiet system, generally not audible at all in a ‘normal’ environment. Under heavy load the fans do speed up a little, however it is still a very quiet system and ideal for a living room environment – for instance connected to a high definition television.
