Lian Li are a name commonly associated with luxurious, high-end cases, often with excellent watercooling and modding capabilities. Today we’ll be looking at something completely different from the Taiwanese company, in the form of a PSU. This is a new direction for Lian Li – will they be able to carry over their reputation for producing extremely high quality products?

Today I’ll be taking a look at the Silent Force 650W unit, designed to power your PC quietly and efficiently. Here’s a quick intro courtesy of Lian-Li:

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 silent-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.

And here’s a quick look at the features list for the Silent Force range of PSU’s:

1. SILENT Force complies with the newest Intel standard ATX 12V V2.3.
2. SILENT Force complies with the newest EPS 12V 2.91.
3. Environment friendly design for energy saving by Active PFC (>.9) / High efficiency (>80%).
4. Power Failure Detector with OVP/OCP/OLP/SCP/UVP/OTP.
5. Support multi-core CPU and Multi GPU/graphics cards system.
6. Support over-clocked CPU ,GPU, and RAM System hardware, best stability power output.
7. PCI-E connector with bead-core protection to minimized EMI for clean output.
8. Modular Cable Management.
9. Deliver FULL rated power output.
10. Universal Input, automatically adjusts for 100V to 240V power grids.
11. 135mm silent-bearing fan and Japan made main capacitors ensure best product reliability.
12. D connector for easy connector-removal.
13. External case coated with unique paint finishing.

The feature list doesn't give away a lot about the units themselves, but is nevertheless rather impressive, with a whole host of technologies buried away inside the unit.

Today I will be looking at the smallest unit in the range – the 650w (for those who require a bit more juice there is also a 750W and 850W unit available). Here’s what the specification for the unit looks like:
