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.

Excellent...another PSU...I would never need to buy. Once again can we have some 'sane' PSU reviews?CrazyElf - Friday, April 24, 2015 - link
The reason why I don't consider the sub-1000 watt as big is because the larger watt PSUs seem to cost exponentially more money than the ones that are cheaper in terms of price:watt output.That being said, never skimp and buy cheap PSUs.

It's not about "cheap", it's about the output. Probably less than 1% of power users would need something this big. My system is an overclocked i7 930, 12GB of ram, 2-1TB hd's, 3 ssd's, a gtx970 SC, lg blu ray burner. It has never drawn more than 350W from the outlet. under normal circumstances it's about 150W for web browsing, or just general work. Goes up to 250W with most games. So I agree with jabber, it's not a "sane" psu for the vast majority of users.jabber - Friday, April 24, 2015 - link
Indeed, some of us aren't in our teens/20's any more and want quality, reliability and VFM, not just moar power! Plus a lot of us are moving to 'smaller boxes'. The term 'PC enthusiast' these days doesn't just mean flames/dragons on the case and lot of LEDs. It's not the turn of the century anymore.nathanddrews - Friday, April 24, 2015 - link
Right, some of us are beyond our 20s and have more disposable income and like to build more robust overclocked, quad CF/SLI systems that require bigger/better PSUs. This review is helpful to those people.Fortunately, the "majority of users" don't matter in enthusiast-level reviews. Titan X, 295X2, 5960X, etc. "Most people" don't need more than a random, budget 500W PSU. Those PSUs are a dime a dozen.
1. Go to Amazon/Newegg.
2. Sort by highest rating.
3. Purchase the first one under $60.

nobody is saying to stop these reviews of extreme psu's , just add some that the majority of the enthusiasts can make practical use of. The last several psu reviews on this site have been for extreme psu's like this, they are ignoring a huge segment of the market. The last several reviews have been for a 1200W unit, 2000W unit, 1050W unit, 1500W unit.jabber - Saturday, April 25, 2015 - link
Some people really don't have a clue what 'enthusiast' means. It doesn't necessarily mean build the biggest and most expensive. Some of us have more subtle tastes.cruzinforit - Saturday, April 25, 2015 - link
You are an idiot, please do not give people purchasing advice on computer hardware ever again. Not all sub 1kw psus are created equal, and in fact Andyson has made some sub Par ones themselves lately.See here

That was awfully snide. Work on manners?Dansolo - Wednesday, April 29, 2015 - link
Grow up. Most of us realize that every single game is playable with high settings without ever touching SLI/CF and that using SLI/CF just adds a ton of problems. It's actually mainly the younger people who want these useless things while the rest of us aren't living with our parents anymore and have a mortgage and other hobbies like cars.It is absolutely a valid comment to point out that AAT's reviews have been very out-of-touch with the community. Personally I rarely read an AAT review these days for this exact reason. The only reason I even clicked this review is because I was curious if Andyson makes decent PSUs at all.
