Enermax Platimax D.F. 1200W PSU Review

Cross-Load Tests & Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V, and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V, and 3.3V) as point zero. The ambient temperature was between at 30°C (86°F) to 32°C (89.6°F).

Load Regulation Charts

Efficiency Chart

The highest efficiency region is between 210W and 510W at +12V, with load on the minor rails staying low. After all, modern PCs don't draw much power from the 5V and 3.3V rails.

Infrared Images

We applied half-load for 10 minutes with the PSU's top cover and fan removed before taking photos with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

Temperatures inside the PSU are elevated, since only the bridge rectifiers and APFC converter use heat sinks. The rest of the components, including all FETs, are mostly cooled by bus bars and the boards onto which they are installed.

We also notice high temperatures from the solid and polymer caps surrounding the +12V board. What worries us most are the heated-up electrolytic caps, since those are the ones prone to failure under tough conditions.

    The DFR would not be that bad at adding dust to the case if it does it each time you start your PC. If DFR kicks in each time you resume from sleep i do not expect to see dust all over the case but if DFR is only activated once or twice a year then yes you will be adding dust to the case assuming it actually detaches from the PSU.

    I'm afraid Teardown video is about thermaltake grand rgb.

    Enermax platimax df 1200w video is uploaded in Aris's youtube channel

    Yes there is a problem with the video. We are working on it! I am sorry for the confusion!

    As a side note, those two platforms share many similarities.

    I prefer to read the teardown analysis. I usually find that to be the most interesting part of the power supply reviews. Thanks for the high quality work that you do in putting these together.

    I love your reviews. please don't get me wrong :)
