Tiny GeForce RTX 3060 12GB Appears Online With No External Power Connector
A highly unusual version of Nvidia’s GeForce RTX 3060 has surfaced online, and it may be one of the smallest RTX 3060 graphics cards seen so far. Shown in a Chinese video, the compact GPU uses a single-slot design, a blower-style cooler, and a low-profile layout that makes it look closer in size to a smartphone than a typical desktop graphics card.
The most surprising detail is not just its size, but its power setup. Unlike a standard GeForce RTX 3060, this tiny model does not include any external power connector. That means it appears to draw all of its power directly from the PCIe slot, which normally supplies up to 75W. For comparison, a regular RTX 3060 is typically rated around 170W, although it can be power-limited to lower levels. Running an RTX 3060-class GPU within PCIe slot power limits is a major compromise.
The card includes only two display outputs: one HDMI port and one DisplayPort. Its minimal design suggests it was built for very specific use cases, such as ultra-compact PCs, custom small-form-factor systems, or machines that lack the space and power cabling needed for a standard graphics card.
According to the video, the card may have been modified using a shunt mod, a technique that changes how the graphics card reports or senses power consumption. By altering the power-sensing circuit near the PCIe interface, the card can potentially be forced to operate under a much lower power target. This could explain why monitoring software reports unusual figures, including board and chip power readings that may not reflect the card’s actual power use.
Performance, however, takes a major hit. While a normal RTX 3060 can boost much higher, this compact version reportedly struggles to maintain core clocks above 900 MHz. That is far below the expected boost clock of around 1777 MHz for a standard RTX 3060.
The performance results make the trade-off even clearer. In 3DMark Time Spy, the tiny RTX 3060 scored around 4821 points. A typical GeForce RTX 3060 can often score around 9000 points or higher in the same benchmark. That means this ultra-small version delivers roughly half the performance of a regular RTX 3060, and its score can even fall behind older mainstream graphics cards such as the GeForce GTX 1060 and Radeon RX 580.
Cooling is another major limitation. The compact blower-style cooler reportedly allowed the hotspot temperature to rise above 90 degrees Celsius. With such a small heatsink and restricted airflow, the GPU appears to throttle heavily under load. The combination of limited power delivery and weak cooling prevents the card from performing anywhere close to a normal RTX 3060.
Still, the design is interesting. While it is not a good choice for gamers looking for full RTX 3060 performance, it could appeal to builders working with extremely tight space constraints. Some small-form-factor PCs do not have room for a dual-slot graphics card, and some prebuilt office systems lack external GPU power cables. For those scenarios, a single-slot RTX 3060 12GB that runs entirely from the PCIe slot could be useful, even if its performance is heavily reduced.
This tiny RTX 3060 is best viewed as a niche experiment rather than a true replacement for a standard model. It shows how far GPU makers and modders can push compact graphics card designs, but it also highlights the unavoidable limits of power and cooling. A GeForce RTX 3060 without an external power connector is possible, but the cost is lower clock speeds, high temperatures, and a large drop in gaming and benchmark performance.
