24 Fixed Drive Power Supply:

• 950W 2+1 hot-swap redundant PFC

The 24 drive Rave2K has 3PS, redundant. (950W hot-swap) The system pulls for a total of just about 600W. All of the power supplies run at the same time but share the load and if one fails the others pick up that load.  Can have two fail and still be good as each one is rated for up to 950W.
