This psu performed incredibly well, it remained rock solid throughout the testing. I was very impressed with the numbers and the minimal fluctuation between load and idle This power supply comes with a ton of features which should make any gamer or enthusiast shout with glee. You have full 3 way sli, sli and crossfire support, and under 100% load you are still running at a whopping 8% efficiency. The auto fan control ensures that when you want to run idle as quietly as possible your psu won’t be running the fan at 100% 24/7 which should prolong the life of your power supply fan considerably.

Would I recommend this PSU? Yes, for some, if you want 6 rails of 12v pumping out major juice for your quad fire or quad sli setup then this isn’t the psu for you, but if you would like a top quality high end psu for performance OC and decent enough power for middle end gaming then this is the perfect choice. The rock solid voltages should keep your OC nice and steady and keep your games running without a hiccup.
