Enermax Platimax 1000w Super Overclock Edition PSU Review

Simulated Load Results (Graphs)

Enermax Platimax 1000w Super Overclock Edition PSU

Simulated Load Results (Graphs)

Because I understand that not everyone enjoys getting a headache from trying to read the tabulated results over on page 4, this page is dedicated to some pretty looking graphs that sum up the majority of the results in an easily digestible format. 

When viewing the graphs you need to bear in mind that the highest and lowest values on the Y-axis (voltage) represent the maximum and minimum voltages allowed by ATX specifications. If the results should fall outside the graph at any time, then that's an instant FAIL. However, merely staying inside these boundaries does not necessarily indicate a good PSU. In order to display truly great voltage regulation, a PSU must stick as closely as possible to the thick white horizontal line (ideal voltage) as possible.

You will also notice that the graph is split into three sections as depicted by the Green, Amber and Red backgrounds. These indicate normal usage (green), heavily uneven load distribution (amber) and overloading of the PSU (red). For the most part all we need to worry about is how it performs in the green section, but good performance in the other sections will undoubtedly earn the PSU extra brownie points.


It looks like we're off to a good start with the +3.3v rail which sits at a supremely accurate 3.33v in test one and drops by only 0.10v by the time it hits full load in test four. This stability also continues into the cross-load results where we can see the application of load on only the +3.3v and +5v rails on TX1 has very little effect on the output, and neither does the load only being placed on the +12v rail in TX2. In fact, the only place that the Platimax shows signs of weakness is during the TMax test which overloads the PSU by 333w.


The +5v rail follows suit with an almost exact trace of the graph from the +3.3v rail. Voltages start of at 5.03v in test one, which is pretty damn good (and shows that Enermax aren't artificially increasing the idle voltages so that the load voltages appear to be better) and dip to 4.94v by test four giving a fluctuation of 0.09v from idle to full load. The cross-load results match those of the +3.3v rail, whereas the TMax overload result is ever so slightly better.


Moving on to the +12v rail, we can see from the graph that it doesn't follow the trend of the other two rails, but is in fact even more stable with only a very shallow gradient representing the 0.14v voltage fluctuation from the idle to full load results. The cross-load results are also admirable with only a small dip in voltage output in TX2 when the +12v rail is subjected to a full load of 998w. Furthermore, unlike the +3.3v and 5v rails the +12v rail does not suffer in the TMax load test, with the output staying perfectly in-check at 11.98v.

Efficiency is one of the primary selling points of the Platimax unit and therefore it's relieving to see that it manages over 90% efficiency across tests 1-4 and peaks at 95.6% efficiency during the cross-load test TX2. Most importantly of all though is that our results back up Enermax's claims to an 80PLUS Platinum badge with 94.69% efficiency at 50% load (94% required), 93.44% efficiency at 100% load (91% required) and 90.35% efficiency at 25% load (~90% required).

Now let's move on to the raw data results and ripple testing over on the next page...

Really looks the kahunas, but as above the cables :/

Gotta agree 100% great power supply just the cables look like they came off a Huntkey or some other cheap and nasty PSU one of the reasons I don't recommend them to friends and such a shame really, cause they are such a good unit.

Cable shables I dont have a case window so dont give a crap. Im just sad they didnt put one of there lovely silver fans like they had the gold ones in the other's.

I'd really like to visit the Enermax factory, because I'm willing to bet that they've got some sort of 10 mile squared underground storage facility just for the rediculous ammount of cable sleeving that they purchased in bulk back in the late 90's.

Yeah,must be some rediculous decisions about cable-sleeving.Their psu`s are top notch,high quality and good performance,but fail hard in cables department.

Shame about the cables

I have two Enermax PSU's and will continue buying them.

...but my problem with the cables isn't that they're ugly (I can abide the brown Noctua fans after all). When installing, my problem was that they were maybe too rigid and difficult to bend.

Considering the cost of these incredible units if if Enermax or a 3rd party company produced fully braided cables for theses (hint hint BitFenix!) I would buy one of these and the Braided cables to go with it in a Heartbeat and Im sure there are ALLOT of Enermax owners taht would too!

Actually, I do agree with you, my Enermax Liberty PCI-E cables were stiff IIRC, good PSU's, its still going strong, has outlived the PC!
