Conclusion

With the AX1200i 1200 Watt, Corsair presents a very good power supply. More than 92.7 Percent efficiency at 50 Percent load is a very good value and as a result thermal dissipation power is low. This implicates a noise level which is low too because there isn't much heat to be removed by a fan. In the case of this power supply the fan is being turned off as long as the load stays below 20 percent. Always practical is a cable management and furthermore we like the number of integrated cables. There really is enough in the delivery to make any enthusiast happy.

A cable management is always a good thing because of the simple reason that it allows the user to only connect the cables really needed to wire a system as neatly as possible. With twelve molex connectors and sixteen SATA connectors it shouldn't be a problem to wire an absolute high-end system. Also the fact that you can natively connect a three-way-SLI/Crossfire setup shows the AX1200i's preferred field of application. There is even plenty of power left to overclock a setup which uses three cards.

A very special goodie is the software you get with the this PSU. You can for example create different profiles. Therefore it is possible to change background pictures and then arrange differente thermal readouts at specific places over the picture. Furthermore you can read out CPU, CPU and PSU temperatures. There are even more monitoring functions. The software is able to display CPU load as well as fan speeds. As you might expect there is also a possibility to adjust the fan fan speed of the PSU. Overclockers will like the opportunity to completely disable OCP for the PCI-Express connectors.

If we look at the performance values, the Corsair AX1200i 1200 Watt shows very good stability under load conditions. If we look at average deviations, we see that they are very low on all different voltages. Therefore the power supply does it's job in a rock solid manner.

For the Corsair AX1200i 1200 Watt receives very good five out of five stars.
