Introduction

Lian Li are perhaps the most reputable high quality PC chassis manufacturer and one of the oldest companies in the industry. They design and manufacture cases almost entirely made out of aluminum and the quality is always class leading.

While Lian Li focus heavily with chassis they have slowly began to design and manufacture other products as well in the last couple of years. These products have been mostly accessories and usually were better suited for their own cases.

Today's review is not about a case or an accessory though, as recently Lian Li unexpectedly released two series of high performance PSUs dubbed 'Maxima force' and 'Silent Force'. We are going to put the Silent Force S750GE 750W PSU to the test and see if Lian Li's latest products can live up to the legendary reputation the company has.

Packaging and Bundle

The Lian Li Silent Force 750W unit is supplied in a well designed cardboard box with a carrying handle. There is very little artwork on the box, but the product's features are very clearly noted at the rear side of the package. The cardboard box is very sturdy and everything is very carefully packed inside, so it should be perfectly safe during shipping.

Inside the box you will find a small manual, a basic AC power cable, mounting screws and a pouch with all of the modular cables stored inside.
