Hot Test Results
As shown in the following tables, the Cooler Master V1200 Platinum offers excellent power output quality. Our instrumentation recorded a maximum ripple of 38mV on the 12V line under maximum load, which is no small feat for a line supplying over 85 Amperes. The severe cross-loading of the voltage lines has little effect on the output stability, and it hardly affects the voltage lines any different than a very heavy balanced load. It also displays excellent voltage regulation, at 0.75%, 0.8% and 1.0% for the 3.3V, 5V and 12V line respectively.

High ambient temperatures have little impact on the performance of the Cooler Master V1200 Platinum, even smaller than that of the almost identical SS-1200XP3. The average nominal load (20-100%) efficiency drops to 93.0% and the maximum efficiency is 94.1% at 50% load. Technically, this unit would maintain its 80 Plus Platinum certification even if the test took place with an ambient temperature of >45°C. (Note that the 80 Plus certification tests take place with an ambient temperature of 25°C.)
As expected, the cooling system maintains a similar profile with the PSU inside the hot box -- the higher ambient temperatures just make it even more aggressive. The fan once again starts at 20% load, but the speed of the fan is now rapidly increasing as soon as the load increases any further. Even at 50% load, our instrumentation was reading over 44dB(A), a sound pressure level that would surely be rated as uncomfortable by the vast majority of consumers. If the load is over 800 Watts for prolonged periods of time, the sound pressure level goes over 50dB(A), creating a hostile environment for any typical consumer/commercial users.

No, users with a <800W system would be better off going with a different PSU that is semi-fanless. As stated in the review even at 800w the sound level is 50db, dropping 600w which would be near typical you get about 44db. You would be better off getting a model such as the corsair hx1000i whose fan doesnt even spin below 500w, and costs $60 less. Hell, you dont even need a 1kw PSU for most builds that arent sli or cfx, you could even get a 800 watter that is semi-fanless and you'd be better off, in price and performanceFriendlyUser - Saturday, November 22, 2014 - link
Great review, as usual. I would really like to see more reviews of units in the 700-800W sweet-spot. You can already imagine SLI/Crossfire and some decent overclocking in that range. Situations that require anything over 1000W are less frequent, even in tech sites like this one.Pork@III - Saturday, November 22, 2014 - link
Too noisy. Bad work!Valantar - Saturday, November 22, 2014 - link
It's fascinating to see reviews of these massive PSUs, but personally I'd be more interested in seeing reviews of lower powered units as well - exactly to see how the mentioned high end features trickle down. Also, with the launch of Maxwell 2, it seems to me that low powered PSUs would be more relevant than previously - a GTX 970 should be able to run off a 400W (or even smaller!) PSU. How about a round-up of ~450W units?The Von Matrices - Sunday, November 23, 2014 - link
For the people wondering about the who uses these huge power supplies, one large market for these >1000W power supplies is Bitcoin/Altcoin ASICs. Many of the boxes require 90A on the 12V rail, all supplied through the PCIe connectors.The Von Matrices - Sunday, November 23, 2014 - link
Also worth mentioning that people with ASICs have noise as one of their lowest priorities since the ASICs themselves generate 70-80dB.NithinJoji - Monday, November 24, 2014 - link
Found something amazing (400W PSU with TITANIUM Certification!!!!!!!!)http://www.plugloadsolutions.com/psu_reports/FSP%2...
