Review of SilenX LX-4600 Luxurae Fanless Power Supply

This posting is my personal review of a SilenX LX-4600 Luxurae Fanless Power Supply. I purchased two units for different applications. One unit is for my home theater pc and the second was an industrial application in a dusty environment.

I purchased the power supplies from Directron.com for about $55 each. The order shipped promptly and the units arrived in good condition.  My first disappointment came when I opened the box. As advertised the unit had a heat sink where there is normally an exhaust fan. However, attached to the outside of the housing was a small fan to circulate air inside the housing. The documentation was lacking and no where on the Directron site did it mention a fan. Also on the housing was a circulate nob that had no marking or documentation. Lastly, the power supplies came set to 230 volts and not 115 volts!

The first unit worked perfectly and apart from my disappointments I was mildly impressed. The second unit didn’t work so well. It was DOA (dead on arrival) and to make matters worse it fried the hard drive!

Upon re-examination of the site where I purchased the units I found three alarming concerns.

1. Directron will pre-test the unit for an extra $5 per unit.
2. After Googling to find other vendors of SilenX power supplies only Directron and Axiontech were listed.
3. The SilenxUSA.com website sells the same LX-4600 unit for over $230!? Why can Directron and Axiontech sell the unit for under $60?

I realize some times parts are DOA and the fact that the DOA unit damaged a hard drive can’t be avoided. My primary concern is the site had misleading images and no description of the internal fan. It remains to be seen how the DOA unit is resolved by the manufacturer/reseller.
