In data center racks today, there is little space between a graphics processing unit (GPU) module and modules connected to it, such as power supply or input-output modules. This leads to the possibility of adverse thermal events and is also ergonomically undesirable. This disclosure describes techniques for auxiliary power connection to GPU trays. The described techniques provide increased operational space for operators. The described power cable interface can function as a power plane for distributing power in transverse directions. With appropriate voltage regulators, the power cable interface can function as a power supply for CPUs that lack floor space. Along with a substantial reduction in or elimination of safety and ergonomic risks, and reduced insertion force, the described power cable interface also has higher power-delivery capacity compared to existing techniques.
