GIGABYTE Shows Off G-Power Accessory for GeForce GTX TITAN

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.

i feel sorry for the poor guys that have to solder those gigantic wires to some small, finicky contact points! :laugh:

looks a mess tbh and that poor titan getting all beat up like that, and I wouldn't like to lose a warranty on an expensive card!

If they solder it from the side shown in the second picture...
"how I apply cooler?"
(other than LN2, that is)

Eh, extreme modder and competitor application only it seems.

Yea, that looks like 4 gauge wire.. lol :laugh:

Yup, that's how I wanted my rig to look!

But seriously, I like innovation and all, but this.... Seems like a waste of time for those guys.

It's only meant for people who OC with LN2.

Oh, don't ruin my moment of poking fun :(

i.e. Thanks, captain obvious.

The idea here is that when you burn up your GPU card that you'll buy another one and thus increase sales. ;)

EVGA untouchables
10 phases made up of
PWM: VT1185M PWM
MOSFETs: VT1185SF(45A) or VT1195(40A)
Inductor(current limit): Coiltronics FP4-150 inductors good for 42A per phase

and 10x42 =420A total

GIGABYTE G-Power
6 phases made to Ultra Durable 5 Standard:
PWM: IR3563A
MOSFETs: IR3550 at 60A per phase
Inductors(current limit): 60A custom made inductors

so 6x60=360A total


However GIGABYTE can always make an 8 phase model that can do 480A, otherwise this 6 phase is enough. The numbers listed are in amperes not watts, so this isn't power, just current.

It isn't a cheap rip off, the IR3550 provide the highest power density and are extremely expensive, however it prob will be cheaper as it is almost half the number of phases of the EVGA one, and it also doesn't have any extra VRM for the memory. Still its a pretty good contender. The GIGABYTE one also seems as if it takes in a 24-pin connector too, this would allow you to just hook up a PSU to the G-Power and not worry about loading its other rails perhaps(that is a just a guess, but maybe they have a system where using the 24-pin helps load the PSU so you can isolate that PSU from the rest of your system. .

BTW if you look close that the new OC board.

definately day late and dollar short, if gigabyte wanted to do this they should have done it right and done 12 phase FTW!!!
