TPU reports Gigabyte has developed the G-Power accessory for the GeForce GTX Titan, an add-on card that provides supplementary voltage regulation. The card is soldered onto the reference GeForce GTX Titan PCB, it stabilizes power and prevents voltage droop from breaking extreme overclocks.
The device is a small PCB with high-capacity power leads on one-end, which need to be soldered on to the reference GeForce GTX TITAN PCB, and a combination of 24-pin ATX and 8-pin EPS connectors on the other. Between them is a 6+1 phase VRM, with components that appear similar to the ones used on GIGABYTE Ultra Durable 5 motherboards, consisting of 60A ferrite core chokes, International Rectifier PowIRstage IR3550 driver-MOSFETs, and International Rectifier IR3563A controller. The G-Power module stabilizes power on the GTX TITAN PCB, preventing voltage droop from breaking the overclock. There's no word on how GIGABYTE plans to sell these.
