請益 Dell r730 GPU - 電腦

大家好

我目前手上有一台dell r730 (750w x 2 電供)，然後之前插1080 ti (TDP 250W)時可以work，
但當我換插rtx 2080 (TDP 230w) 或 k20 (TDP 225w) 時，nvidia-smi會跳出以下error

Unable to determine the device handle for GPU 0000:82:00.0: Unable to communicate
with GPU because it is insufficiently powered.

This may be because not all required external power cables are attached, or the
attached cables are not seated properly.

想請問一下，是有什麼地方我沒注意到的嘛?
