ASUS Dual GeForce RTX 5070 OC Edition 12GB GDDR7: Compact Two-Fan Blackwell for 1440p
The DUAL-RTX5070-O12G puts NVIDIA's RTX 5070 in ASUS's compact two-fan Dual cooler. It boosts to 2572 MHz in OC mode (2542 MHz default), with 6,144 CUDA cores, 988 AI TOPS and 12 GB of GDDR7 at 28 Gbps on a 192-bit bus. At 249 mm long and 2.53 slots it carries NVIDIA's SFF-Ready mark, so it fits small-form-factor cases. Two Axial-tech fans on dual ball bearings, a phase-change thermal pad and a vented backplate keep it cool, and a dual BIOS switch picks Performance or Quiet mode. Power comes from a single 16-pin connector, with a 1-to-2 adapter in the box; ASUS recommends a 750 W power supply.
🎮 1440p Gaming with DLSS 4
Fifth-gen Tensor cores run DLSS 4 with Multi Frame Generation in supported games, fourth-gen RT cores handle full ray tracing, and Reflex 2 with Frame Warp cuts latency in competitive shooters.
🧰 Creators & Local AI in a Small Build
The ninth-gen NVIDIA Encoder (NVENC) speeds exports in DaVinci Resolve and Premiere Pro, Studio drivers keep creative apps stable, and ASUS bundles MuseTree for local AI image generation on the card's 988 AI TOPS.
Cooling, Build & Connectivity
Four views of the card, each matched to what ASUS built into it.
Two Axial-tech Fans
Each fan has a smaller hub for longer blades and a barrier ring that raises downward air pressure into the heatsink. Both spin on dual ball bearings, which ASUS rates at up to twice the life of sleeve bearings, and stop completely below 50 °C at low load.
Fin Stack, Thermal Pad & 16-pin
The top edge shows the heatsink fin array the fans push air through. Under it, a phase-change thermal pad melts to fill the gap between the GPU and the cooler, and MaxContact enlarges the heat-spreader contact by 5%. The single 16-pin power connector sits on this edge.
Vented Backplate & P/Q Switch
The backplate stiffens the PCB against flex, and its open end lets air from the second fan pass straight through the fins and out of the card. The MODE switch beside it selects the Performance BIOS for lower temperatures or the Quiet BIOS for a gentler fan curve at the same power target.
304 Stainless-Steel I/O Bracket
Three DisplayPort 2.1b outputs and one HDMI 2.1b drive up to four displays, up to 7680 × 4320, with HDCP 2.3. ASUS makes the bracket from 304 stainless steel, which is harder and more corrosion resistant than a plain steel plate.
📊 AI Performance Index (AI TOPS)
AI TOPS measure the Tensor-core throughput behind DLSS and local AI features. Figures from NVIDIA's official specification pages.

Power Supplies
ASUS recommends a 750 W power supply. A native 16-pin (12V-2x6) cable avoids the bundled adapter.
Processors
Pair with a current six- or eight-core CPU so the GPU is not held back in high-refresh 1440p gaming.
Monitors
A 1440p high-refresh monitor is where DLSS 4 and ray tracing on this card pay off most.
PC Cases
At 249 mm and 2.53 slots it is SFF Ready, so compact Mini-ITX and Micro-ATX cases are an option.
