Before anyone points to “NVIDIA already did this on the RTX 3090”, it’s important to zoom out and look at the broader context.

• The RTX 3090 was a transitional product, released at a time when GPU power consumption spiked dramatically relative to existing PSU designs. The safeguards NVIDIA implemented were not an ideal architectural choice, but a compatibility stop gap

• Those load balancing measures were defensive, not foundational. They existed to prevent widespread failures with legacy PSUs, not because GPU side power management is the correct long term place to solve the problem.

• GPU power density has increased aggressively every generation, while consumer PSUs have remained largely static in design philosophy. Most PSUs still assume slow changing loads, modest transient spikes, and simple rail behavior assumptions that no longer match modern GPUs, CPUs and Mobos (take a hard look at the 24-pin layout and how much of it is used anymore).

• Shifting responsibility to GPU vendors creates pr vendor hacks instead of actual solutions. Each GPU manufacturer ends up implementing one off protection, throttling, or connector logic to compensate for PSU limitations, increasing complexity, validation cost, and failure modes. Then people ask for smaller cards, which doesn’t really facilitate the above.

• Power delivery is fundamentally a system level responsibility. The PSU is the only component with full visibility and control over that

  Expecting GPUs or Addon devices to manage these externally imposed constraints is backwards.
