Wow! What a power supply! We could not only deliver its labeled 525 W power at 50° C but also maintained efficiency between 85% and 90% all the time! In fact this is the power supply with the highest efficiency we reviewed so far. Not only that. We could pull almost 600 W from this unit still with 85% efficiency. That is impressive.
Another highlight from this product is its noise level. This was the quieter power supply we reviewed to date.
We were really happy to see that the bad results we got with Enermax Liberty DXX 500 W are a problem with this particular model and not a general problem with Enermax.
The number of connectors that come with this power supply should please even high-end users, with seven SATA power plugs and three connectors for video cards (two of them 6/8 pins).
The only problem with this power supply is its price. Costing around USD 150 in the USA it is too expensive for the average user, even though it is worth every penny, especially on the long run, as you will save money on your electricity bill due to the higher efficiency provided by this product.
If you want to save some money and still want to have a power supply with high efficiency, we recommend Antec EarthWatts 500 W (around USD 90) and Corsair VX450W (around USD 80). This model from Corsair is in fact a 500 W and internally it is identical to Antec EarthWatts 500 W, but comes with just one video card auxiliary power plug.
We could also complain that over power (OPP) and over current (OCP) protections didn’t kick in as we expected, but since this power supply survived to our overload tests without burning we don’t think this is really an issue.
