Enermax Revolution ATX 3.0
Enermax now also has its irons in the fire among ATX 3.0 PSUs. The “weaker” variant has a rated power of 1000 W, the more powerful up to 1200 W. The main attraction of these PSUs (not only the new Enermax Revolution, but ATX 3.0 models in general) is the 16-pin connector for external power supply of GeForce RTX 4000 graphics cards. And the Enermax PSUs have two of them, which is one of the competitive advantages compared to other solutions.
The range of ATX 3.0 power supplies expands with two new Enermax models – ERA1000EWT (1000 W) and ERA1200EWT (1200 W). These power supplies are from the Revolution model series, which Enermax has reserved for the midrange.This also corresponds to the 80Plus Gold efficiency certification. More expensive higher-efficiency variants (Platimax or MaxTytan) are also likely to come out, but at a later date. So from the get-go, Enermax saw fit to start with more affordable models – the reverse of how BeQuiet! did it (it first introduced the Dark Power 13 and then the cheaper Pure Power 12 M line of power supplies).
The Enermax Revolution ATX 3.0 power supplies use large, 135 mm fans, but at the same time they maintain a short chassis that is only 150 mm long. The fan turns on only from a load of 30% (at lower loads the cooling is purely passive).
As far as cabling is concerned, it is possible to connect up to two 16-pin 12VHPWR connectors to the power supply. One directly or via native 12+4-pin and the other via 2×8-pin. Eventually, you can run two powerful GeForce Ada Lovelace graphics cards within a single build without the need for third-party adapters. However, it’s important to point out that only one, the primary one, has “600-watt” parameters.
The secondary 12VHPWR connector is more suitable for cards with a TDP of around 300W, i.e. for the RTX 4070 Ti and RTX 4080. For powering the RTX 4090 this connector is unsuitable. As such, the power supply is in any case also eligible for a combination of RTX 4090 (powered by native 16-pin) and RTX 4080. The +12V branch is capable of delivering 83.3A stably, or up to 100A in the case of the more powerful, 1200W variant. The short-term load for 100 μs, which is defined by the ATX 3.0 standard, can be up to double that.
Full specifications including all connectors can be found on the Enermax product page.
The advantage of ATX 3.0 over ATX 2.x power supplies is, for example, the requirement for significantly higher efficiency at low loads. We have covered the general details of this new standard in a separate article.
The new Enermax power supplies are already in stores and are sold on Newegg or Amazon.de. The MSRP is 250 EUR (for the 1000 W Revolution ATX 3.0 model) and 290 EUR (for the 1200 W).
