SilenX 400w 0dBA Luxurae PSU

silenx-400w

Introduction

I have reviewed a lot of power supplies over the years here at OCmodshop and now I look at the SilenX 400w. This power supply claims to be the quietest active cooled power supplies on the market. I have done reviews on many other silent power supplies from many other companies. Some have been as quiet and they boasted to be and others were much louder than they should have been. This power supply features Over Voltage Protection, Over Power Protection, and Short Circuit Protection. All of these features will ensure that the power to your system is stable and fixed. I don’t like loud systems at all, before I got this power supply I was using the True Silent 450w PSU I previously reviewed because it was the quietest I have encountered so far. I will be using the True Silent power supply to compare this SilenX one to see which is quieter.

The power supply does not come boxed, rather it comes in a plastic bag with the power cord supplied. The power supply was shipped via USPS Priority Mail and was in one of their boxes. The power supply was protected well during shipping with packing material and came undamaged. I think that SilenX should really look into getting a box for their power supply, for many different reasons.

The power supply doesn’t boast any flashy designs or cool colors however that is not the purpose of this power supply. Silence is what the main goal of the unit is and there are tons of features to help achieve that. It would be nice if there was something extra as far as looks is concerned with this power supply if it did not raise the price.

The back of the power supply has an on/off switch, 110/220v toggle, and power connector. The 80mm fan that is used as an exhaust has a unique blade design and hybrid immersion bearings to lower the noise level. Instead of the traditional metal screws the fan is held in place by a silicone composite fan vibration dampening system. The fan on a power supply is what makes the noise so the quieter the fan the quieter the it will be.

Because this power supply is designed to be silent there is only one fan so there needs to be some decent heatsinking inside of the unit to keep it cool. One thing I noticed is that the screws holding the cover in place had Loctite or some similar product on them to keep them from vibrating. Small details like this show that the manufacturer has really taken time to make the best possible product. After getting the cover off I found that there was a impressive amount of heatsinks inside. You can also see on top of one of the heatsinks that there is a thermal probe which controls the fans RPM.

This SilenX 400w has pretty standard connections including: 6 Molex, 1 berg, 1 Auxillary, 1 12v, and 1 ATX. None of the cables have sleeving or any other form of cable management which would have been nice to see but is alright none the less. The cables also don’t look to be too long which is the case of many other power supplies.
