IBM NeXtScale System Planning And Implementation Manual page 53

Table 3-5 on page 34 shows the quantity supported of compute nodes with GPU
trays attached and two 300 W GPUs installed. Only 1300 W power supplies are
supported and only 200-240V AC input supported. The supported 300 W GPU is:
Intel Xeon Phi 7120P, 00J6162
