That connector can deliver up to 600 watts, enough for an RTX 5090. It has six +12V pins, so an even split puts roughly 8.33 A on each.\n\nThe split is rarely even. Resistance and manufacturing imperfections push more current onto some pins and less onto others, and the pins that take the extra load are where the melting starts.\n\nThe dongle sets two thresholds. If any pin goes above 9.5 A, it lights orange and buzzes intermittently. Above 12 A, it lights red and buzzes continuously. If that persists for 195 seconds, a feature called VGA Black Screen Protection kicks in. Super Flower describes it only as a way to buy time to check connections.\n\nThe idea is not new. Cooler Master sells a GPU Shield Adapter Cable that works on much the same principle, and some power supplies, including those with MSI's GPU Safeguard+, build in similar monitoring. Uniko's Hardware, which spotted the dongle, reported that it is currently available only in Taiwan, as part of a power supply bundle.\n\nThe 9.5 A trigger sits about 14 percent above the even-split figure, and the red alert at 12 A is roughly 44 percent above it. That is a fairly tight band. Still, a dongle can only report a problem, not fix an unbalanced connector. The more telling detail is that several companies now sell warning systems for a standard power plug on a card that can cost well over $1,000.","[\"nvidia\",\"12v-2x6\",\"power-supply\",\"graphics-cards\"]","2026-10-21T09:59:41.000Z","2026-10-21T10:24:11.421Z","2026-10-21T10:24:11.619Z","published",null,[24,30],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Fix three problems: (1) the 'smoke detector rather than a sprinkler... leaves the intervention to you' line, repeated in the dek, contradicts the article's own description of VGA Black Screen Protection, which triggers after 195 seconds, so describe what that feature does and avoid overstating the lack of intervention; (2) the '$2,000-class card' price is not in the source, so remove it or support it; (3) 'three vendors selling separate monitoring gear' mischaracterizes MSI, whose GPU Safeguard+","resolved",{"id":31,"reviewer":26,"round":32,"reason":33,"status":29},"editor-r2",2,"Delete the leftover drafting note 'The source describes it only as an attempt to buy you time... so what it does to the card is not spelled out', and say plainly that Super Flower describes Black Screen Protection only as a way to buy time to check connections.
