MSI is working on the Lightnings, EVGA on a Kingpin version, so ASUS must have something under wraps as well we figure. You guys probably can remember something developed under codename Poseidon a while ago. Well, that now expands and leaves the gossip arena as ASUS offers a sneak peek of a liquid cooled GeForce GTX 780 Ti  which will be part of the Republic of Gamers lineup and will feature a DIGI+ VRM, highly-durable Black Metallic Capacitors and the DirectCU H20 cooler which combines air and liquid cooling to allow for better performance and quieter operation.

DirectCU H20 packs two dust-proof fans, three heatpipes, a large heatsink and a water block. Based on the prototype card showcased by ASUS earlier this year we can assume the ROG Poseidon will have three working modes - air only, liquid only and combined (air and liquid). There's no information just yet on clock frequencies, price tag and or a release date.
