The XP-650 is labeled as a 650W power supply, but has a peak output of 700W. The power supply has a combined 12V rail of 44A, which is more than enough to support SLI and CrossFire platforms. The XP-650 has four separate 12V rails all of which can be combined to form a single power rail thanks to what Mushkin is calling RailFusion Technology. When RailFusion occurs the green LED light on the back of the power supply will turn on letting you and anyone else look at the back of your case that you are pulling some serious power.
This is all great and everything, but they will have to be high quality to compete with others on the market. Can’t wait to see how they perform in reviews though. Check it out at Legit Reviews.
