The MaxTytan is the flagship product in the lineup of Enermax power supplies. This is the largest capacity it builds and promises to deliver excellent efficiency. Semi-fanless features makes sure this PSU stays quiet up to ~70% load. It also has a very unique feature in that it will show you the power wattage being delivered on an LCD panel right on the PSU.


Enermax Technology Corporation is a company that is well known in the world of power supplies and general computing alike. Founded in 1990, Enermax has made a name for itself by providing solid performing power supplies, among other computer components, cases, and accessories. Enermax' current lines of power supplies encompass a wide range of products targeted at various market segments. In addition to being a retail presence with its Enermax brand power supplies, Enermax Technology Corporation used to be one of the few true OEM designers of power supplies. Its power supplies however, only rarely showed up under other labels including Grow Up Japan, Sapphire, and its house brand Lepa with that time of independent design and production seeming to have passed. Today, we are looking at the our second example of a product from Enermax's MaxTytan line; the MaxTytan 1250W (EDT1250EWT). This power supply comes from CWT.

Channel Well Technology (CWT) was founded and began manufacturing power supplies in 1993. Since 1993 Channel Well Technology products have shown up under various guises including Antec, Xclio, 2theMax, CWT, Thermaltake, Xigmatek, Enermax, and Corsair. While most familiar to our US users from when they used to provide OEM services for Antec, CWT is one of the more complete OEM manufacturers as they have a fairly high level of vertical integration providing transformers all the way up to its well designed independently regulated SMPS.

Maxed Out?

The Enermax MaxTytan 1250W is the second product we have seen from Enermax's MaxTytan lineup of power supplies. The big difference today being the last MaxTytan unit we saw was a very pedestrian 800W compared to today's 1250W. When we step up from 800W to 1250W we certainly begin to scale outside of mainstream products into true enthusiast territory, an area where Enermax has catered to for a long time. So, the big thing we are going to be looking for today is how this MaxTytan 1250W does in upholding the Enermax name in the high end enthusiast realm and how it does relative to some tough competition (once you are in this kind of capacity range everyone steps up their game). So, let's see if Enermax does as well (or better than) than those units today. First, let's see what Enermax has to say about this unit and its product placement:

MaxTytan 1050W & 1250W, the flagship lineup of ENERMAX power supplies, is 80 PLUS Titanium certified. The fully modular PSUs are engineered with Wattage Meter, the digital panel allowing users to instantly identify the real-time system power consumption. This series incorporates the ultra-silent Twister Bearing fan with Dust Free Rotation technology that helps decrease dust build-up on fan grill and blades. In addition, the PSU is designed with a semi-fanless control to deliver 0 dBA silence before it reaches 60%~70% operating load. Moreover, MaxTytan 1050W & 1250W come with an exclusive accessory, COOLERGENIE, the intelligent 2-in-1 fan controller that provides system fans with semi-fanless control and fan-delay function. MaxTytan 1050W & 1250W are surely a perfect solution for high-end gaming systems, heavy-duty multi-GPU workstations, or even power-hungry mining rigs.

Let's now take a look at what we get when we purchase the Enermax MaxTytan 1250W power supply in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
