NVIDIA T4 Power Consumption

Dear Sir/ Madam, recently we launched a PC project with building in a T4 and Windows 10 platform. We designed the power supply based on 70 watt power consumption specification of T4. But one of our customers fed back that they lost the T4 when burning in their AI model to maximum. And they found the T4 could run over 90 watt as the system at busiest moment. If this is possible to run over the 70 watt specification, please how is the technical limitation of T4? And is there any method to limit this to avoid the hardware broken?
