Super Flower VGA 12+4 pin OCP Dongle 防显卡熔化新配件
Here's another gizmo to prevent your graphics card from melting - wouldn't it be nice if 12+4-pin connectors weren't a cause for concern at all?
电源制造商 Super Flower 推出 VGA 12+4 pin OCP Dongle，通过监测 12V-2x6 连接器电流防止 RTX 5090 等显卡因过载熔化。该配件在单引脚电流超 9.5 A 时亮橙灯间歇蜂鸣，超 12 A 亮红灯连续蜂鸣，持续 195 秒触发 VGA Black Screen Protection。目前该 dongle 仅在台湾随电源供应器捆绑销售。
Power supply manufacturer Super Flower has launched a new accessory that sits between a graphics card and its power cable to ensure neither ends up a hot, expensive mess as too many Nvidia cards seem to be.
It's called the VGA 12+4 pin OCP Dongle. It's a big lump of plastic and ARGB LEDs that measures for high current across the power pins that make up the 12V-2x6 (or 12VHPWR) connector. This connector is capable of delivering up to 600 watts—enough for an RTX 5090—but it's overcurrent (a current that exceeds the cable/connectors ratings) that could cause a catastrophic failure.
There are really six 'hot' +12V pins on the connector. That means each of those pins needs to carry around 8.33333 amps or thereabouts. That power load doesn't stay perfectly balanced between the pins, due to resistance and imperfections, which means some pins get less amps, while some get more amps. It's when they get a lot more amps that things start to get melty.
Super Flower's OCP Dongle keeps a close watch on those amps, and will indicate when any pin exceeds 9.5 A.
If any one pins is between 9.5 - 12 A, the dongle will light up orange and emit an intermittent buzzing sound.
If any one pin exceeds 12 A, the dongle will light up red and emit a continuous buzzing sound. If this continues for 195 seconds, VGA Black Screen Protection is triggered, which tries to buy you some time to check your connections.
It's a pretty neat solution and one that's not entirely new to me, as I've got something very similar in my own PC: Cooler Master's GPU Shield Adapter Cable. It operates on more or less the same principle, with lights and buzzers to let you know if it's all going to hell in a handbasket.
That might be a more reliable choice right now, as Uniko's Hardware, who spotted this Super Flower dongle, suggests it is only available in Taiwan right now, included in a bundle with a power supply. There are power supplies that offer similar features, too, such as those with MSI's 'GPU Safeguard+'.
Though why I have to deal with this gnawing worry about my expensive graphics card is another thing entirely. Surely it doesn't have to be this way?
