Gigabyte will apparently stick with Nvidia's plan not to launch custom GTX Titan graphics card but in order to make overclockers happy, it will apparently launch its G-Power, a 6-phase power supply PWM circuit board that should improve overclocking capabilities.
The Gigabyte G-Power is actually a 6-phase power supply PWM circuit board that needs to be soldered directly to the GTX Titan which makes it limited to just a few enthusiasts willing to poke and solder on one expensive graphics card. The G-Power apparently needs a 24-pin ATX and 8-pin connector in order to work and should provide additional power to the GTX Titan making it suitable for some serious overclocking with LN2 cooling, of course.
Gigabyte has a couple of overclockers in its lab that are currently playing around with the G-Power and we are sure that we'll see some results pretty soon.
