Silverstone PP02

Silverstone kindly sent us a couple of products to look at as well. The first is the PP02 which is an foam lined ABS plastic cover designed to help with the noise produced by a power supply. The cover mounts directly to the power supply using the standard PSU mounts. Because standard screws are too short to hold a PSU securely, Silverstone includes a set of extra long screws with the PP02.

One possible concern with using a product like this is the extra heat that it may generate as it does impede some of the airflow coming out of the power supply. To test that, a 3.6 prescott system was dual prime95ed and 3dMark2005 was looped for an hour with and without the cover. The onboard software readings showed no tempurature difference whatsoever.

As for noise levels, the cover had an effect of altering the noise signature of the sound. The high pitched sounds from the PSU were muffled and brought down a couple of octaves. The difference was not very significant though. If you'd like to get an idea of how your system will sound after mounting this device, simply place your hand (assuming you have large enough hands) over your PSU exhaust. Because the PSU exhaust is typically facing away from the user, one will not notice too much of a difference.

Silverstone PP01

Cases such as the Silverstone Tj-05, the Lian Li V1000 and the Antec P180 are gaining in popularity which is causing some issues for users as they do not have the typical ATX layout which can cause issues with certain brands of power supplies. Though Silverstone power supplies tend to offer very good cable lengths, there are those such as Seasonic which offer incredibly short leads. It then becomes neccessary to make use of extensions should one desire the use of certain PSU and case combinations and the PP01 fulfills that need well.  Additionally, one would use these cables should the need for a 24-pin to 20-pin adapter come up.

The unfortunate downside to the use of extra connectors is that, if they are not made well, they will introduce higher levels of resistence in the lines which would ultimately lead to voltage drops in systems.  To check these, we took a look at motherboard voltages before and after the extensions were mounted and they revealed no large discrepencies in the power being supplied.

These cables are not something that everyone needs, but when you need it, you know where to go.

Silverstone CP01

Silverstone demonstrates here that not all SATA cables are made equally. The red cable pictured is one that is typically included with motherboards these days. These cables work, but are susceptible to not working so well when you bend them at the junction of the cable and SATA head. To the right of course, is the Silverstone SATA cable which is approximately twice as thick as the standard OEM cable. The connectors are also reinforced with metal which will help with cracking plastic connectors.

For most, the need to buy new SATA cables will probably never come up. However, if you are in a situation where you often swap out harddrives, then this cable will be perfect due to its enhanced construction. We'll be using this cable along with another OEM cable over the next couple of months (maybe even years) to see which one stops working first. Check back on this article as we give updates.
