The High Power Direct12 BR 850 W power supply seems to be internally identical to the Enermax NAXN 82+ 850 W. It can really deliver its labeled wattage at high temperatures, and it presented efficiency between 82.2% and 86% during our tests and very low noise and ripple levels. One of the highlights of this product is the cable configuration, with eight video card power connectors, allowing you to hook up to four high-end video cards, and 12 SATA power connectors.
This unit, however, has some issues. First, when we turned it on for the first time, it started making an annoying ticking sound. Upon checking it out, we discovered that one of the cable ties inside the unit was touching the fan. This was an easy fix, but we wonder if the average user will dare to stick a screwdriver through the fan mesh to push the cable that was causing the problem.
The second minor problem, which unfortunately seems to plague all Chinese manufacturers, is the website written in “Engrish.” How much would it cost to hire a proofreader and avoid fantastic sentences such as “Its tailor-made single +12V rail is the arsenal for you to become Guru of Overclocker!” (Note to High Power: the correct structure would be “Its tailor-made single +12V rail is the arsenal for you to become the overclocking guru!”)
All these problems are minor. The only real problem we found with this unit was with its +3.3 V output, which drops below the minimum allowed at full load.
The manufacturer suggested price is USD 160, and we know that online stores rarely sell power supplies at their suggested price; they always give discounts. Therefore, if it is sold for, say, USD 150, it will compete directly with the Corsair TX850M.
