These are the same, gospower, but you can still consider them integrated since they do have the additional cables between psu and miner, for regulation, they are just not mounted to side of unit due to size. They are solid units, considering all the failures we heard of with the S17 psu's thus far, i would be more comfortable with these regardless.
Of all the gear tested the Avalon a1041 with the larger psu and this larger fan was the best to run at low speed. It was due to the unattached psu. If I were to use 5 more units. I would have zero issues with the loose psu. I got 31th at lower speed setting and it was pretty quiet. Makes it good for a home miner.
