- NVIDIA GPUs: Use nvmlDeviceGetPowerUsage() via pynvml - AMD GPUs: Read from hwmon power1_input sysfs interface - Display power in watts with color-coded bar (0-300W scale) - Add power history sparkline for each GPU - Track power in gpu_power_hist alongside util and mem histories
- NVIDIA GPUs: Query power management limit via nvmlDeviceGetPowerManagementLimit() - AMD GPUs: Read power1_max from hwmon sysfs - Display shows current/limit (e.g., '450.0/600.0 W') - Power bar scales to each GPU's specific limit instead of fixed 600W - Falls back to 600W default if limit cannot be queried
