Internally, the Platimax II 1200DF is built on a modern RSY platform with a solid set of components. Rubycon caps are on the primary side, Nippon Chemi-Con and UNICON on the secondary. Build quality is good overall. Soldering is clean and nothing stood out as being rushed or cut back. It is a modern design as well, LLC resonant with DC-DC for the minor rails, so all as expected really for a unit at this level.

Thermals are handled well. Even pushing the unit up towards full load in a 35C environment, temperatures stayed under control. The fan is doing its job, shifting enough air through the unit without things getting out of hand.

Enermax have gone with a 135mm Globe Fan here, dual ball bearing, rated at 0.45A. On paper that sounds like it could be quite aggressive, but it is not spinning hard for most of the load range. Up to mid load it stays quiet enough, and you only really start to hear it once you move past 800W or so. At full load we measured 35.7 dBA. Not the quietest result we have seen, but it never becomes irritating either. A quality high grade FDB fan would likely have helped matters in this regard.

Feature set is what you would expect. Full ATX 3.1 and PCIe 5.1 support, native 12V-2×6 connector for 600W GPUs, and good transient handling. Cables are decent as well, individually sleeved and easy enough to work with.

Right now we have no UK pricing information, apart from a link to Amazon DE which currently shows an asking price of £127 for the black version and £164 for the white version. This is quite different to the information we were fed from Enermax directly, highlighting a price of $229.99 for the Black version (HERE) and $239 for the white version (HERE). We reached out to Enermax for some details on pricing and I will update this page when I get more information. Where it actually lands in the UK is going to matter.

Overall, this is a solid power supply. It performs well, it is built properly, and thermals are under control. It is not the quietest unit in this class when pushed hard, but for most systems it is not going to be an issue. If pricing ends up closer to the lower end we have seen, it becomes a very easy recommendation. All we have right now however are links to the DE Amazon website.

Pros

• Strong electrical performance across all rails.

• Very good efficiency levels.

• Solid internal component selection.

• Good thermal control under load.

• ATX 3.1 and PCIe 5.1 ready.

• Compact size for a 1200W unit.

Cons

• Not the most refined acoustics at higher loads.

• Ball bearing fan choice shows under heavy load.

• Pricing currently unclear.

KitGuru says: A solid 1200W power supply that gets the important things right. Not the quietest under load, but well built, efficient and worth a look if pricing lands where it should.
