Monitoring starts to matter when the workstation becomes expensive enough that guessing feels risky. With one GPU, many people only notice problems after shutdowns or random instability. With two or three GPUs, I would rather see warnings earlier, especially around power spikes and connector stress. During a discussion about a rendering box at work, someone mentioned Seasonic PRIME ENTERPRISE because it is aimed more at professional systems than casual gaming builds. I would not say every creator needs that level, but for multi-GPU workstations running paid jobs, it is worth looking at. The useful part is not just high wattage; it is the idea of keeping an eye on power behavior before a small issue turns into lost work or hardware trouble.
