With NVIDIA clamping restrictions on graphics card makers' ability to make custom design PCBs for its flagship GeForce GTX TITAN GPU, the likes of GIGABYTE are opting for the next best thing - creating accessories that enthusiasts can mod their GTX TITAN graphics cards with, at the cost of product warranties. A little earlier this month, the company unveiled its WindForce 450W VGA cooler, which is capable of handling GTX TITAN. At a more recent event, it showed of G-Power, a supplementary voltage regulation module, which is similar in principle to EVGA EPower and ASUS Matrix PWM.

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.
