Cold Test Results

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post.

Note: As the Andyson Platinum R 1200W cannot follow the test protocol guidelines without overloading its 3.3V/5V lines, the load derating factor DV of these two lines is being reduced to 50%. To explain why, we will be putting up a pipeline post shortly to explain the matter, as it applies to several other units.

Even if its low load efficiency is not much to look at, the Andyson Platinum R 1200W meets the 80Plus Platinum certification requirements with ease. It manages a maximum conversion efficiency of 94.2% at 40% load and an average of 92.8% within the nominal load range (20% to 100% of the unit's capacity). When the load is reduced below 20%, the efficiency plummets, dropping to 81.7% at 10% load and further down to just 74.7% at 5% load. This was to be expected, as this is how SMPS PSUs operate. A 5% of a unit this powerful corresponds to an output of 60W, ample to power a modern system while it is idling, so higher low-load efficiency would be more than welcome.

Due to the very high efficiency and the presence of adequately sized heatsinks, the Andyson Platinum R 1200W maintains very low internal temperatures without overworking its cooling fan. The temperature of the heatsinks barely surpassed 65°C under maximum load, when 100 Amperes were flowing from the transformer to the distribution PCB. The cooling fan displays a "stepping" behavior, staying entirely quiet up to 40% load and then stepping up each time that the load increases. Even with a load of 1kW, the noise levels are tolerable for daily use, with the fan pushing the borders of comfort only at maximum load.

    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.

    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.

    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.

    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.

    That was awfully snide. Work on manners?

    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.
