The new PC Power & Cooling Silencer Mk II 650 W is a very good power supply, presenting better performance than practically all 650 W power supplies we’ve reviewed to date. It only loses to Seasonic X-Series 650 W, but this model with 80 Plus Gold certification is more expensive.
The only flaw of the Mk II 650 W is the high noise level at the -12 V output, a problem that won’t affect most users, since this rail is only used by some add-on audio cards. This problem, however, must be noted and that is the only reason we are giving this unit our Silver Award instead of our Golden Award.
Also, it would be nice if this unit had four video card power connectors instead of only two.
