If the computer you are on right now is completely silent, or has been modded beyond recognition, this paragraph probably wont apply to you. I want you to do something. Turn off any music playing, cut off any outside sources of noise, and just concentrate on how loud of a "hum" your computer emits. In most cases, the hard drive(s) are responsible for three quarters of this "hum." The last quarter, depending on how loud the fans in your computer case are, almost always comes from the PSU. Well, more specifically, its coming from a large, low RPM fan sandwiched between a highly inefficient fan grill and dozens of warm capacitates and aluminum heatsinks. Airflow within PSUs is very restricted. They must be cooled to some extent to serve their function. In most cases, PSU manufactures skimp out on the quality of the parts they use in order to increase profits. To compensate, they they are forced to increase cooling for stability, and thus turn a blind eye towards the noise issue. Well, it looks like times have changed with the introduction of the SilenX PSU series.
Reliable. Powerful. Silent. I'm glad AHANIX chose this order of words to form their caption. It shows that even though the entire series of SilenX PSUs stresses the feature that it is very quiet, they still put reliability and power before it. I mean, what use is a quiet PSU if it isn't reliable and not powerful?
"These power supplies offer the quality and reliability that you need for mission critical applications. Plentiful cables and a generous amount of overhead for the most demanding systems. Built to tolerate environments that exceed its own specifications, sometimes by as much as 50%, these power supplies are rugged and built to withstand what you throw at it! - SilenX Power Supply - Amazing performance, truly silent in operation."
The SilenX series includes 200W, 250W, 300W, 350W, 400W, 460W, 530W, and 550W variations. Today, OCA will be testing the 350W model. Lets see if AHANIX is true to its words over the SilenX PSU!
Packaging and Specs
The SilenX PSU comes in a very simple, cardboard box with a four sided black cover that has a few things written on it. The entire thing is then plastic wrapped. The side shot of the box shows what model is contained within.
Inside, the PSU and power cable are bubble wrapped together. And that's all you get, for $79. No manual, no warranty information, no stickers, nothing. This better be a damn good, silent PSU!
Here is a small table of specs:
14 dBA - SilenX ATX 350 Watt PSU
115V/230V @ 8A/5A
±5% Load Regulation
±1% Line Regulation
Over Power Protection: 105%~150% of max load
Looking at these specs, there's nothing spectacular about this SilenX PSU from a power perspective. In fact, 28A max output on the 3.3V line and 15A max output on the 12V are bit behind the competition, i.e. the 32A and 17A we found on our "whisper" Enermax EG365P-VE FCA which is also a 350W PSU. Will the SilenX really be as reliable and powerful as printed? One things for sure however, that at only 14dBA, you can bet this PSUs going to be silent.
