What happened
Tom's Hardware reports that Nvidia's DLSS 5 pushes power draw to 647W, with the 16-pin power connector reportedly running hotter than the GPU die itself, described as straining thermal and power limits. The excerpt provided is almost entirely subscription and newsletter boilerplate: it contains no test methodology, no measured connector temperature in degrees, no board partner or SKU named, and no date for when DLSS 5 ships or which GPUs support it.
Why it matters
There is not enough here to make a purchasing or build decision on — no measured temperature figure, no PSU sizing guidance, no hardware list. If you are speccing a machine for local AI inference or gaming on a 16-pin card, treat this as an unverified headline and wait for a review with actual instrumentation before sizing your PSU or case airflow; if the 647W figure holds, a 1000W-class PSU with 12V-2x6 headroom becomes the planning assumption rather than a nice-to-have.
Discussion angle
AI-driven upscaling is shifting more work onto the GPU die and its power path — does the 16-pin connector remain the weak link, and what should Malaysian builders do about PSU and airflow planning if 600W-plus cards become normal for local inference rigs?
