Enermax Platimax DF 1200W PSU Review

If you are looking for a powerhouse of a PSU that is shoehorned into what is a tiny ATX package for the wattage, the Platimax D.F. (Dust Free) PSU may be worthy of your short list. As the name suggests, this PSU sports excellent power efficiency and is fully modular and that could make your HEDT build a lot easier.

Overview

The first thing we are going to look at with the Enermax Platimax DF 1200W is its packaging, accessories, and documentation. While normally none of these items is a make or break item for a power supply the packaging quite often contains a lot of information about the product we are purchasing. The inclusion of an owner’s manual that provides actual information about our product is also of great help. Accessories are almost unnecessary with a power supply as the unit is self contained, unless it is modular, but there are cases where a manufacturer can include useful accessories to make installation, routing, and use more efficient.

Today, the packaging of the Enermax Platimax DF 1200W is very much to almost identical to what we saw with the Platimax DF 600W. That said, there are, obviously, some differences as today's unit is 1200W in capacity versus 600W in capacity. On the front of the packaging, we see a shot of the Platimax along with a line of seals indicating various features that the unit has such as a Twister Bearing Fan, Japanese Capacitors, "Dust Free Rotation," 80 Plus Platinum efficiency, and a 5 year warranty. Looking at that 80 Plus seal and then the 80 Plus website does turn up the fact that this unit is certified for 80 Plus Platinum. Also, looking back at that 5 year warranty, the warranty is starting to be a bit on the shorter side of things these days when you consider what we find for most high end units from other vendors. When we flip to the rear of the packaging, we find a bit of advertising as well as the power table (reproduced below) and the cable count (reproduced below) for the 750W through the 1200W models. When we look at the advertising that we see here, we find all of the same items that we saw with the 600W model including the bit about "Dust Free" rotation. In case you missed the 600W model review, what this means is the fan controller appears to not only stop the fan when shutting off but also will reverse the rotation direction to dislodge dust that has settled and this is coupled with a long life Twister Bearing fan. When we move along to the sides of the packaging, we do not find anything new.

The power information for the Enermax Platimax DF 1200W is what we would expect from a modern power supply but there are a few things that differ from the majority of 1200W units we have seen in the last few years. The Platimax DF 1200W has an advertised 12v capacity of 100A or ~100% of the unit’s total possible capacity if necessary. This capacity is, however, split over four 12v rails with 12v1 and 12v2 having individual capacities of 25A each while 12v3 and 12v4 have individual capacities of 40A each. When we look at how those 12v rails are configured, we see that 12v1 and 12v2 only feed once connector each (the ATX 24 pin connector and the EPS connector respectively) while the larger capacity 12v3 and 12v4 each support a number of connectors more fitting for their larger capacity. The minor rails have an individual capacity of 25A on each of the 3.3v and 5v rail. These values are rather robust for these rails in this day and age. Paired with this power distribution we find six PCIe connectors, twelve SATA connectors, and four Molex connectors. Generally speaking, this arrangement should get the job done for users. However, at 1200W there will be some people who may claim that more PCIe connectors would be appropriate. For most users, though, this would be a waste as multi-GPU gaming seems to be on the downswing, once more, leaving mostly cryptomining type applications where tons of PCIe connectors may be useful.

Once we open the Platimax DF 1200W, we find the power supply, modular cables, mounting screws, some zip-ties/velcro ties, the power cord, power cord holder, Enermax case badge, and the user manual. The user manual that comes with the Platimax DF 1200W is very similar to what came with the Platimax DF 600W. That means the manual is one page folded like an accordion and reprinted in 13 languages. On this page we find the power table that was on the package (so it covers all of the units from 750W to 1200W), some information about connectors, the warranty information, and some installation instructions. Once more, this is not exactly the thorough documentation we used to see from Enermax. Let's move on now to the unit itself.
