Hot Test Results
As the following tables indicate, Andyson really outdid themselves. The Platinum R 1200W displays exceptional power quality, especially considering the very high power output of the PSU. The maximum voltage ripple on the 12V line is just 26mV at maximum load, under a massive >92A current. The voltage regulation is equally amazing, with a change of less than 0.6% for every voltage line across the load range.

We should mention that this PSU does not have a clear temperature rating. This most likely means that it has been rated at 40°C, as this is the commercial computer PSU temperature standard. However, in order to match the 50°C rating of several high-end products, we perform our testing at temperatures higher than 45°C. We could reduce the ambient temperature of our hotbox testing but we chose not to do so as the results would then not be comparable to those of our previous reviews.
According to the following results, it does not seem that Andyson would have any trouble giving this PSU a clear power output rating at 50°C. High ambient temperatures have very little to no effect on the performance of the Platinum R 1200W, which lost a mere 0.15% of its average energy conversion efficiency. In fact, it maintains the 80Plus Platinum efficiency levels, with the maximum efficiency being 94.1% at 40% load.
Despite the great rise of the ambient temperature, the internal temperatures of the PSU do not rise disproportionally. On the contrary, the rise is almost additive, with the internal temperatures of the PSU rising about as much as the ambient temperature did. The fan displays the same behavior, with the only difference being that its speed starts increasing much sooner, yet reaching the same maximum noise levels nonetheless.

It's not so much the wattage its the size. A lot of us don't need legacy stuff like DVD drives, 4+ HDDs or Tri-SLi for gaming. So we are building smaller PCs. The days of the wardrobe PC are over. Wives and Gf's don't like huge black monoliths that light up like xmas trees. So the issue with the high wattages units are they don't go in smaller cases so easily. Up to 800W should be a standard sized unit no issue. I would have thought a smaller unit could be made up to 600W.KAlmquist - Sunday, April 26, 2015 - link
You should consider buying a fanless PSU.kevith - Sunday, April 26, 2015 - link
Just wanted to mention, that I have a Hiper "Type-R 580w Modular" PSU, that has been running with absolutely no flaws for 6 years and three builds now.meacupla - Sunday, April 26, 2015 - link
Since I see Anandtech being one review sites with emphasis on SSF type computers, I find it odd that they review these massive 1000W+ PSUs.Where are the SFX PSUs from silverstone? 450W and 600W in such a compact size is pretty amazing, and even those can be overkill in the cases they are designed to go in.

Here for the comments as well. I don't even read these useless psu reviews. Would never use such a monstrosity even if given for free!blzd - Saturday, May 16, 2015 - link
Just wanted to voice my opinion for having reviews of reasonable power supplies. Proper power supply reviews are few and far in between, even less so for the reasonable sized ones in the 450-750W range.I had a Lepa 500W Gold rated PSU with 41A on the +12v rail that could not support my GTX 970 upgrade despite it meeting all the system requirements. Had to pick up a 750W EVGA (Seasonic OEM) gold rated to replace it but I can't find proper reviews of any of these "normal" units.
