Lepa G Series 1600W Power Supply Review

LEPA is an Ecomaster company and Ecomaster distributes Enermax products and has Enermax design the LEPA PSU line. So what are our expectations from the current ultimate desktop PSU packing a whopping 1600 watts? Should it be better than a four year old 1600 watt power supplies on the market?


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's current lines of power supplies encompass a wide range of products targeted at various market segments including the MaxRevo, MODU87+, PRO87+, Platimax, Revolution85+, Galaxy EVO, MODU82+, PRO82+, NAXN, LibertyECO, and Tomahawk series. In addition to being a retail presence with its Enermax branded 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 Enermax’s house brand Lepa. This particular power supply is the 1600W model from their "G" series of power supplies (G1600-MA). As with the previous G700 that we reviewed, the G1600 is built by Enermax.

Time to Take a Giant Lepa to the Next Level?

Today’s Lepa G1600 is the 3rd power supply we have seen under the Lepa brand to date. Among the previous outings we have seen some good points from Lepa which are significant given it is a value brand, but today we are stepping into completely new territory for a value brand with this massive 1600W offering. Previous to this unit, we have seen just one 1600W unit (Ultra X3 1600W) and we saw that unit over four years ago. In fact, so limited are the offerings in this upper end of the power supply market that in the time between the Ultra X3 1600W and today's Lepa G1600 review, we have only seen two other units that have approached 1600W in capacity (the SilverStone Strider ST1500 and the Thermaltake Toughpower 1500W). As such, a winner in this range today could be a real coup for Enermax' Lepa brand. This, of course, creates lofty expectations for us today and, as such, it is of great interest to see what Lepa has to say about such a marquee product:

• Powerful 1600W fully rated output, peak power up to 1700W

• Surpassing 80 Plus Gold level (G1600-MA is 80 Plus Gold certified.)

• Full Modular Cabling Design makes system upgrade and replacement easy

• High Density PCB Design makes G1600 only 18cm in depth, providing more space to dissipate the heat inside the chassis

• 135mm ball bearing fan with thermal programmed speed controller delivers silent, cool operation

• Honeycomb-shaped ventilation design increases airflow and keeps power supply cool

• Solid State Capacitors and 105°C Japanese Grade A Capacitors provide great reliability

• DC-to-DC Converter Design ensures system stability

• Full Bridge and Zero Voltage Switch (ZVS) topologies provide superior performance and reliability

• Dual Sided PCB design synergizes PCB layout

• Six powerful +12V rails with high maximum loads offer great compatibility with heavy-duty graphics cards

• Ability to run up to 4-Way GPU (SLI / CrossFire) and Dual CPUs together without difficulty

• Compliance with EU ErP Lot 6 standards (lower than 1W power consumption at standby mode)

• Over Power, Over Voltage, Under Voltage, Over Current, Over Temperature, Short-circuit protection provide great safety to your system

• ATX12V version 2.3 and EPS12V version 2.92 compliant

Well, since all Lepa has to say about this unit is a bullet list, let's move on to see what we have to look forward to when we purchase the Lepa G1600 in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
