Electrical Safety Test Class 1
Manufacturer/Model
Pass/Fail
Lian Li Silent Force 850W
Pass

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and all four 12V lines in turn. The power supply did shut down, and once the short was removed and the unit switched off for at least one second, resumed normal operation. Although listed here at the beginning of the testing section, I tend to leave this test until the very end, in case it doesn't quite go to plan.

The DC voltage load regulation of the Lian Li Silent Force is, on the whole, very good, apart from two minor failures on the +5V0 rail. The +5V0 rail voltage is slightly high, of the order of 50mV, at 100% load at both 110VAC and 230VAC. This is a minor failure, although a failure nonetheless, and wouldn't really cause a problem when installed. The 12V rails all held up very well, and the 3V3 rail remained constant at 3.4V throughout testing, which is excellent.
