Certified Silent Puget Serenity Pro

Puget Custom Computers is no stranger to SPCR readers, as the company has been an active member of the SPCR Certified Quiet/Silent Computer Program for nearly three years. During that time, successive versions of Puget's Serenity PC SPCR edition (and the mini variant) broke acoustic standards for SPCR Certified Computers, not once but a couple of times. Puget does not mass produce systems; each system is custom built to your order. The last refresh of the Serenity was the i7 Sandy Bridge SPCR Edition, certified in January 2011: Its sound pressure level (SPL) measured an astonishingly low 11 [email protected] (the ambient floor of SPCR's tomb-quiet anechoic chamber) at idle and low load, and reached just 12.5 dBA after an hour at absolutely maximum system load.

The latest Puget PC submitted for certification is called the Serenity Pro. The chassis remains the same as in the Serenity, the proven Antec P183 in gun metal finish, with an Asus socket 1155 motherboard and Intel i7 CPU. It differs from the i7 Sandy Bridge SPCR Edition with component upgrades forced by the short product life cycles in IT — an Ivy Bridge CPU instead of Sandy Bridge, a Z77 chip motherboard instead of P67, and so on — but primarily in the choice of graphics card. The last three generations of Serenity systems from Puget all featured a fanless Radeon HD5750 with a fairly modest TDP of 86W, which is what allowed the card to be cooled passively. The Pro has a much more powerful graphics card, an ASUS GTX 670 2GB DirectCU II. This is one short step down the very high performance nVidia GeForce GTX 680 card, capable of playing the latest demanding 3D games at speedy FPS with high detail settings and screen resolution. Its TDP is 170W, definitely a far bigger challenge to cool quietly than the Serenity's HD5750.

Puget stayed with the tried-and-true Antec P183 for the Serenity Pro. The gun metal gray of the Antec case is quite classic, looking professionally subdued yet always reflecting something of its environs.

Here is a comparison of the components for the Serenity Pro versus the last certified Serenity. As mentioned above, there are many differences, mostly subtle and largely a result of ongoing product changes by component manufacturers. The single biggest difference is the graphics card, which increases total power demand by over 80W.
