Asus ROG Poseidon Platinum GTX 1080 Ti – liquid or air cooling

In essence Asus has taken a ROG Strix GTX1080Ti O11G Gaming and bolted on their DirectCU H2O cooler, and in the process they have created the ultimate GTX 1080Ti graphics card. It looks big and imposing with that hefty 2.5-slot cooler, but in addition you get a really tidy backplate, RGB and the Asus Fan Connect II feature.

You might not be in love with the spread of RGB lighting but the fact is that this graphics card looks amazing as the infinity mirrors give the illusion of an illuminated tunnel that passes right through the graphics card.

The overclocked GTX 1080Ti graphics core delivers epic gaming performance, exactly as you would expect, however that fabulous cooler allows the GPU to do its work with very low temperatures and the minimum of noise.

Connecting the Poseidon to a custom loop cooling system is quick and easy but while it reduces temperatures by the best part of 20 degrees it doesn’t deliver any extra performance. Our GPU clearly had a hard limit just north of 2GHz and that was the end of that particular story.

Yes the Poseidon is expensive but blimey, it is impressive.
