Received food for my Corsair case replacing my other 850 Corsair AX power 2years which had broken down (did not start pc in insisting on / off button, a problem encountered by other users). No worries for connection, easy modular cables. Food BUT silent when the fan is switched rubbed on the grid. The fan was inclined ??? Shame for such a mark. But I take my hat off to Amazon that my mail regarding that manufacturer defect problem, directly sent another model replacement very quickly. New set up without any problem and without noise.
