Lian Li Silent Force 850W Review

Price: $209.99


This is the second Lian Li power supply I have tested from the Silent Force range, so please have a look at the Silent Force 750W reviewed here. The packaging, box contents and power supply are identical, the only difference being a few labels and 100 watts more power. The Lian Li Silent Force 850W is, according to the Lian Li website, their highest powered unit available at the moment, so lets see how it performs. If you notice any similarities between this and the Lian Li Silent Force 750W review then I plead guilty, but please rest assured the testing phase is completely from scratch.

"The ever increasing demand of power users for high-end products and outstanding performance has initiated Lian Li to announce a new series of Power Supply Units (PSU) called the 'SILENT Force'. Building from Lian Li’s reputation as an enthusiast brand catering to the ultimate tastes, the product features a 135mm ball-bearing fan, modular cable management, and Japanese Main Capacitors to ensure that the quality and standards, as well as durability of Lian Li products, is as outstanding as our customers expect."

With clean and stable power driving your PC via the SILENT Force PSU and the multi 12V rails output and bead core protection for the PCI-e connectors, failsafe safety protections, and 80 Plus output all combine to give the SILENT Force PSU superior durability than anything else you are likely to get. SILENT Force PSU’s have today what PC power user’s need tomorrow!”

Closer Look:

The packaging for the Lian Li Silent Force 850W is identical to the previous Lian Li power supply I tested, and once again the power supply is packaged in a plain black box with a thin card sleeve for all the necessary information. The information is well laid out and uncluttered, and all sides are gloss black except the back panel. The front gives you an obligatory power supply photograph, which I have to say is top quality, and model and product name and the Lian-Li logo. The bottom left hand corner contains a sticker with the power supply wattage and model number which wraps around to the side to attach the sleeve and give you the same information on the side panel. The back of the power supply sleeve gives you the rather lengthy features list, the more information the better I say, provided the layout remains tidy. On the left hand side we are treated to a series of icons depicting some of the major elements from the features list.



The side panel below gives you small photographs of all the power supply connectors and a table of the named connector types and quantities. A welcome addition on the top is the inclusion of a sturdy carrying handle.



The wrap around sticker is on the left and an adhesive specification label on the right. The side panel also informs us that the power plug is suitable for the EU. The only external difference between the Silent Force 850W and 750W models are these two labels.



Lift the lid and the Silent Force 850W is neatly enclosed in foam. The user manual is in the side space along with a black canvas bag containing all the cabling resting on top of the hard wired power supply cables neatly tied with a wire wrap.



Below is a sneak preview of the power supply along with the user manual and cable bag. The bag is on the large side and contains all the modular cables, power cord and a small plastic bag containg four mounting screws.



The Lian Li Silent Force series has one of the best looking packages I've seen. The information is useful and well laid out, and all the illustrations are top quality and informative. Let's hope the power supply performs to the same high standard.
