Enermax Platimax 1350W Power Supply Review

Enermax is a long standing quality desktop PSU company. It not only specifies and designs power supplies it is one of the few companies that actually build enthusiast PSUs. Enermax today moves it 1350 watt giant into "Platinum" efficiency territory with the new Platimax 1350W.


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, and accessories. Enermax' current lines of power supplies encompass a wide range of products targeted at various market segments including the Platimax, MaxRevo, Modu87+, Pro87+, Revolution85+, MODU82+, PRO82+, LibertyECO, NAXN, and Tomahawk series. In addition to being a retail presence with its Enermax brand power supplies, Enermax Technology Corporation appears to be one of the few real OEM designers of power supplies. Its power supplies however, have only rarely shown up under other labels including Grow Up Japan, Sapphire, and its house brand Lepa. Today, we are looking at our third power supply from the Enermax Platimax line of power supplies with this 1350 watt model (EPM1350EWT).

How Much Better Can it Get?

Today’s Enermax Platimax 1350W is the third power supply we have seen from Enermax’s Platimax product line and, to date, the largest capacity unit we have seen from this line. Previously, we did see the 80 Plus Gold rated MaxRevo 1350W which shares a similar design with this unit so it will be of great interest to see how much progress Enermax has made at the 1350W power level with this design since then. It will also be of interest to see where this unit fits with other units on the market as we are beginning to see more and more units being advertised as 80 Plus Platinum in the 1200W and up range. One of the big questions that come with these single minded advances in efficiency is, "Do these truly improve the unit in any other way?" We will certainly be interested to see the answer to that question today with this unit as we can draw an almost direct comparison with the MaxRevo 1350W. Before moving on though, let’s see what Enermax has to say about this unit:
