I must admit that I really enjoy reviewing high capacity units. This is after all the reason why I acquired so many electronic loads, to be able to torture even >1500W units with ease. As you can imagine, I had a lot of fun with the LEPA G1600-MA since currently it is the strongest PSU available on the market and on top of that it is able to deliver this huge amount of power even on 115VAC power grids with high efficiency and at ambient temperatures that exceed 40°C. On top of that its ripple suppression is very good overall and at +12V it is simply outstanding.
The biggest flaw of LEPA's G1600-MA is the loose voltage regulation at +12V where the deviation exceeded 5% during my tests, although I had utilized most of its connectors. Apparently the pursuit for the highest possible efficiency didn't allow this beast to keep tight regulation on the +12V rail, but on the other hand I can't imagine a system that will be able to draw 130A out of this rail, in order to be able to fully stress this unit.

To sum up, this is a very good PSU with an overall outstanding performance and enough power to feed a dual CPU system with five high-end VGAs and a ton of peripheral devices, water cooling pumps, lighting accessories etc. Also its price, for what it has to offer, is very good since we found many lower capacity units costing way more, and offering less. Apparently Enermax, through LEPA, managed to release the strongest PSU on the market at a competitive price, which will really hurt the competition in this segment. Finally, the G1600-MA easily earns a recommendation from me despite its loose +12V voltage regulation because it is ripple proof, highly efficient and currently holds the title of the strongest desktop PSU, which at the same time manages to meet the 80 PLUS Gold requirements.
