DGX H100 PDU requirements
The cord NVIDIA ships is C19/C20. The PDU must present C19 outlets (or a locking C19 equivalent that accepts that coupler). A C13-only PDU does not feed this system. See C13 PDU, C19 server.
Count: six locking cords in the H100/H200 kit, so six C19 drops if you populate every PSU cord NVIDIA packed. Electrical rating on the cord table: 250 VAC, 20 A, 1200 mm.
Facility power (whips, phases, redundant feeds) is in the NVIDIA site-planning sections of the same user guide. This page covers only the IEC jumper and outlet shape.
