Air or Liquid – Your Choice to Chill

Designed to provide superb performance on air or liquid, the ROG Poseidon graphics card incorporates DirectCU H2O to give you the flexibility and freedom of choice.

Liquid cooling has been a choice for many PC enthusiast as a efficient means of heat removal and increased overclocking potential of carefully selected hardware. However, custom water cooling solutions can be difficult and costly, as original cooling solutions have to be removed and fitted with waterblocks. The ROG team engineered the Poseidon with revolutionary DirectCU H2O to give you the best of air and liquid cooling- providing total flexibility whether you are looking to liquid cool now or later. Venturing into liquid cooling with the Poseidon reduces GPU temperatures by up to 24°C and enjoy ultra-stable overclocking!

Ultimate Performance

DirectCU H2O Hybrid Cooling

Complete flexibility for either air or liquid cooling

DirectCU H2O is a hybrid thermal solution that combines the vapor chamber and water channel with standard G1/4- inch threaded fittings to easily accommodate existing liquid cooling equipment. With liquid, DirectCU H2O achieves up to 140% lower temperatures while reducing noise- up to 3X quieter.

Dust-Proof Fans

25% longer graphics card lifespan

Unique fan design extends longevity by 25% by increased dust and particle resistance while efficiently dissipates heat for optimal performance.

DIGI+ VRM with Black Metallic Capacitors

30% less power noise and 5X greater durability

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 5 times longer lifespan.

ROG LED Light

Pulsates in glorious red when the card is active

Poseidon GTX 780 exceeds your expectations while looking amazing. ROG LED pulsates in ROG red when the card is in use.
