In designing the Poseidon GTX 780 graphics card, ASUS packed in many of premium components you would normally find as add-ons. Additionally, the card features motherboard quality power components, featuring a 10 phase digital power regulation system using ASUS DIGI+ VRM technology coupled with Japanese black metallic capacitors. The Poseidon GTX 780 has the following features integrated into its design: DisplayPort output port, HDMI output port, dual DVI ports (DVI-D and DVI-I type ports), aluminum backplate, integrated G 1/4" threaded liquid ports, dual 90mm cooling fans, 6-pin and 8-pin PCIe-style power connectors, and integrated power connector LEDs and ROG logo LED.

In addition to the high-end power components and unique styling we've come to expect with an ROG-branded video card, ASUS integrated a liquid channel, dubbed DirectCU H2O, into the copper cooling plate for the board's GPU and memory. The liquid cooing channel is U-shaped for maximum heat absorption into the liquid medium with the provided inlet and outlet ports capable of interfacing with any standard G 1/4"-sized barb. ASUS couples this cooling system with their DIGI+ VRM digital voltage regulation system, touting increased power efficiency and durability over previous systems. Use of more efficient MOSFETs, power chokes, and capacitors helps to reduce the operating temperature of the card as well.

Not the best clocker, those liquid results can be done at stock voltage on my EVGA SC.

anyone knows of what material is the waterchannel made of? Copper or AL ?!

Just received mine in the mail. Overclocked to 1200 with 1187 for voltage. Thing is a beast, with my 2500k at 5.01GHz I scored 9300 on Fire Strike 3DMark. I believe the waterchannel is made of AL btw
