Single-Slot RTX 3060 Spotted: No Power Connector, Half the Performance

A bizarre single-slot variant of the NVIDIA GeForce RTX 3060 has surfaced online, offering a compact form factor at the cost of severe performance penalties. This unusual hardware configuration matters to builders of ultra-small PCs who need a GPU that fits in tight cases but must accept significantly slower gaming speeds. The card draws all its power from the motherboard slot, eliminating the need for external cables but triggering aggressive thermal and power throttling.

Compact card draws power from motherboard slot only

The device features a blower-style cooler and a low-profile PCB designed to occupy only one expansion slot. It provides two display outputs, consisting of one HDMI port and one DisplayPort, which limits multi-monitor setups. This physical design prioritizes spatial efficiency over thermal capacity, forcing the silicon to run at much lower frequencies than the standard model.

Specifications

• Form Factor: Single-slot, low-profile
• Power Delivery: PCIe slot only (no external power connector)
• Power Limit: Approx. 75W (modified via shunt mod)
• Core Clock: Sustained ~900 MHz (Boost ~1777 MHz)
• 3DMark Time Spy Score: 4821

Performance testing reveals the card delivers only 4821 points in 3DMark Time Spy, a score that falls below older GPUs like the GTX 1060 and RX 580. The processor struggles to sustain clocks above 900 MHz, despite a theoretical boost clock of 1777 MHz. This throttling occurs because the card uses a shunt modification to bypass standard power sensing, artificially limiting its power budget to around 75W.

While GPU-Z tools may report high power draw figures, the actual consumption remains restricted by the hardware modification. The card targets users with extreme space constraints who can sacrifice performance for physical compatibility. Buyers seeking standard RTX 3060 performance should avoid this variant, as it operates at roughly half the speed of the regular model.
