HPE ProLiant Compute XD685 (HGX B200)
The eight-way XD685 in its NVIDIA HGX B200 configuration, liquid cooled only, in the 5U DLC chassis S4R96A. HPE names B200 support twice in the QuickSpecs, in the supported-accelerator list and in the rule that the H200 and B200 liquid-cooled accelerators must be paired with this chassis, so the configuration is not in doubt. The accelerator kit part number is not recorded: the accelerator table lists two entries both described as HGX B300 with different part numbers, one of which is likely the B200 mislabelled, and guessing which would put an unverified number on a row buyers may quote. Two fifth-generation AMD EPYC processors, 24 DIMM slots and up to 6 TB of DDR5-6400. HPE publishes no system power draw, only twelve 3,000 W supplies, so nothing is summed; compute is NVIDIA's for the baseboard.
