1.1.3

Power Specifications

The DGX A100 system contains six power supplies with balanced distribution of the power

load.

Table 1-4.

Power Specifications

Input

Specification for Each Power Supply

200-240 volts AC

6.5 kW max.

3000 W @ 200-240 V, 16 A, 50-60 Hz

1.1.3.1

Support for N+N Redundancy

The DGX A100 includes six power supply units (PSU) configured for 3+3 redundancy. If three

PSUs fail, the system will continue to operate at full power with the remaining three PSUs.

Note

: If only two PSUs are working, the GPUs will not be available, but the server will still boot.

This is to allow you to gather debug or system logs.

If only one PSU is working, troubleshoot the cause for the loss of power from the other PSUs and
correct. If faulty PSUs need to be replaced, shut the system down and install working PSUs.

1.1.3.2

DGX A100 Locking Power Cord Specification

The DGX A100 is shipped with a set of six (6) locking power cords that have been qualified for

use with the DGX A100 to ensure regulatory compliance. Two locking power cord types are

approved - switch-locking for the PSU side and twist-locking for the PSU side.

WARNING: To avoid electric shock or fire, only use the NVIDIA-provided power cords to connect
power to the DGX A100. For more details, see

Electrical Precautions

in “Safety”.
