In Win Commander II 1200W

Since we've had some 750W and one 520W PSU reviews of late, we thought it might be time for another high-power model. The In Win Commander II 1200W is an 80 Plus Bronze certified power supply with modular cables. In the package we find a large number of modular cables, a user manual, some cable ties, four screws, and one power cord. That last item was a bit of a surprise, as In Win provides a 10A cable while the maximum input current is rated at 15A. In Win should provide a 16A cable, at least if they expect users to actually come anywhere near the 1200W power output. At maximum load and 82% efficiency (80Plus Bronze), the Commander II 1200W can draw approximately 12.7A.

As mentioned in the summary, this PSU comes with four +12V rails. Combined they can deliver up to 1032W. Every single +12V rail is rated for up to 40A, though you obviously won't be able to put that much of a load on all rail simultaneously. +3.3V as well as +5V are rated at 150W combined, while the standby rail is specified with 3A. And in the way of more confusing stuff, the combined power of the large rails is just 1079W with 21W on the -12V and +5Vsb, which means this is really an 1100W PSU; 1200W seems to be the peak power. (We're getting close to the point where that 10A power cord makes sense now....)

In Win uses a fan from Young Lin with the model number DFB132512H. H stands for "high rotations per minute" (1700RPM). This double ball bearing type fan has a peak power consumption of 3W. There are also three guide vanes at the bottom of the fan, where other manufacturer usually use a foil.

    ...another review without comparisons to other products. Seriously, why can't this be done?
  • Martin Kaffei - Saturday, June 11, 2011 - link

    There are many comparisons in the conclusion. But if you are thinking of roundups were we compare every single feature we will find a solution.

    "...merely an average 1200W offering."
    I wondering if merely an average power supply is all that is needed these day's? Since mother board manufacture's today are paying alot of attention to onboard voltage regulation. Does the end user really need a state of the art pwr supply?

    Since many components have a direct connection to the PSU: Yes.
    Moreover the VRM on some mainboards might be relatively resistant, but that does not apply to every one.

    Of course not all systems need the best PSU but if there are important data on your PC or if the PC is very expensive I would spend much money in the PSU.
