Test Results


Our load tests leverage a couple of FAST ATE active load testers and a variety of other equipment such as a hotbox, oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.


The five tests being performed are based around five concievable setups that are out there:-


- Test 1 is based around a standard gaming system that would place a load of about 20%.
- Test 2 is delving into an entry-level SLI setup, pulling about 50%.
- Test 3 starts going into an enthusiast's SLI or Crossfire setup, drawing a 65% load.
- Test 4 is for an SLi/Crossfire setup with high-end cards incl. 3-way arrangements pulling 100%.
- Test 5 takes the configuration for test four, but adds overclocking.
- Test 6 utilizes the maximum capacity of the testing equipment or the PSU; whichever is higher.


The test equipment pulls a max of 1000 Watts during these tests.






I was pleasantly surprised that throughout the tests, this unit managed to exceed the results posted on the 80 Plus site, even if it was only by a very slight margin. Although each system will vary as far as power consumption goes, the Active PFC should keep the overall efficiency within these boundaries.


Final Thoughts


If you hadn't picked it up from the rest of the review, I adore this unit. I adore the efficiency, I adore the design, I adore the overall thought placed into this product. I even adore the packaging.


I think about the only thing I don't adore about this is the price. But even then, it's just worth it. This is the result of a company taking the time to manufacture quality over quantity. I may be gushing, but this power supply truly deserves it.


If it fits within your budget, I highly suggest picking it up.
