I just started using these on the warehouse rigs and can report back that they are working just fine.  Finally got everything setup correctly to run the entire rig off the one 2400w PSU with the ATX adapter.  This greatly reduces cost for the mining rigs as previously I was using a 1600 G2 and a 1000 G3 for each rig.

Here's a short video showing the PSU in action.
