ROG Poseidon-GTX780-P-3GD5
ASUS ROG Poseidon GTX 780 Delivers 12% Faster Game Performance than Reference Designs
  • DirectCU H2O: 45°F (7°C) cooler on air. 75°F (24°C) cooler with water.
  • DIGI+ VRM with 10-phase Super Alloy Power: Deliver 30% cleaner power noise and 2.5X greater durability.
  • Japan-made black metallic capacitors: 20% Better temperature endurance and 5X longer lifetime usage.
  • ROG LED light: Pulsate in glorious red when the card is active.
  • GPU Tweak: Modify clock speeds, voltage and more via an intuitive interface.
  • GPU Tweak Streaming: Lets you share on-screen action in real time – so others can watch live as games are played.

The ROG team engineered the Poseidon with revolutionary DirectCU H2O to give you the best of air and liquid cooling and the flexibility to choose if/when you want to move to liquid cooling. Venturing into liquid cooling with the Poseidon reduces GPU temperatures by up to 24 degrees for ultra-stable overclocking!


Up To 140% Lower Temperatures & Up to 3X Noise Reduction

DirectCU H2O offers complete flexibility for air or liquid cooling with a hybrid thermal solution that combines the vapor chamber and water channel with standard G¼-inch threaded fittings to easily accommodate existing liquid cooling setups. With liquid, DirectCU H2O achieves up to 140% lower temperatures while reducing noise by up to 3X.


25% Longer Graphics Card Lifespan

Unique fan design extends longevity by up to 25% by preventing dust & particle buildup on the heatsink, while efficiently dissipating heat for optimal performance.


20% Wider Range of Operating Temperatures

Poseidon GTX 780 features a 10-phase Super Alloy Power along with acclaimed DIGI+VRM (voltage -regulation module). DIGI+ VRM is a digital voltage regulation that provides ample room for overclocking and performance tuning while reducing power noise by 30%. Along with Super Alloy Power specially formulated concreted chokes and harden MOSFETs to withstand greater stress and heat, Poseidon GTX 780 also uses Japanese-made black metallic solid-state capacitors for 20% better temperature endurance and a five-time longer lifespan.


As the perfect fusion of form and function, the Poseidon GTX 780 leaves no stone unturned, incorporating a Republic of Gamers logo that pulses in red when the card is active, letting you know it's ready for action.



Tuning Panel: Intuitively adjust GPU clock speed, voltage, memory clock, and fan speed.

User Profiles: Store up to 4 custom profiles or access preset Power Saving (S) and Gaming (G) modes.

Live Update: Automatically check for and update graphics card BIOS on your Poseidon GTX 780.
