Having a look at the exterior of the In Win Commander II Bronze 850 Watt PSU is next on our list.  The entire unit is painted in a military green color and finished off with yellow stencil type graphics. One thing we look at right off the bat is how heavy a power supply is, and this one weighs in at about 5.5 Lbs! The weight alone of a power supply can go a long way in determining the quality. If you don’t believe it, grab a hold of one of those $40 600 Watt power supplies out there, and when you are done laughing you will see what we mean.

Starting at the top of the unit you will find a label attached with a brief rundown of the amperage of the different rails, wattage specifications and the usual hazard warnings that are standard fare on most power supplies. The bottom of the unit houses the 13.5cm smart fan and has a black protective grill covering it.  Both sides of the power supply feature a slotted ventilation area, the left side is where the yellow stenciled graphics are positioned. The back of the unit is entirely made up of honeycomb mesh which will aid greatly in the air flow characteristics of the unit.  Also at the back is where you will find the rocker switch for turning the power on or off, and the power cord receptacle. The front of the Commander II features six slots for attaching the various modular cables.  The hardwired cables extrude from the front area as well.

Next we split the housing apart to have a look at the guts of the In Win Commander II Bronze 850W unit.  The 13.5cm fan used in the unit is manufactured by Young Lin Tech Co. The fan has a maximum RPM of 1800 and a CFM rating of 95.01.

The next series of pictures will give you a good look at the inner components. We found all the solder points to be very well done and very sturdy to the touch.  You can also see the DC to DC VRM design implemented for this Power Supply. There are three large heat-sinks but unfortunately not a lot of space between components for good air flow. The two main caps are of Japanese origin and manufactured by Panasonic. The DC to DC modules are comprised of solid capacitors.
