Galaxy Designs GeForce GTX 460 with High-Grade Components

Galaxy, known for coming up with some of the widest varieties of non-reference design graphics cards, is now working on a new GeForce GTX 460 PCB that makes use of a high-grade digital PWM power supply. Still in its design-phase, the PCB is white in color, though there's a chance of the final product differing in color. The PCB draws power from a 6 pin, and 6+2 pin power connectors. It makes use of a 6+2 phase PWM circuit controlled by a Volterra VT1185M, with VT1157SF PWM ICs. It also makes use of high-C capacitors, as well as NEC-made Prodalizers to condition power. This PWM circuit can supply up to 240A, with conversion efficiency of over 85%.

What it means for overclockers of course, is that they can tinker with voltages to their hearts' content, if their cooling permits it, without any capacitor mods. It is also extremely efficient, so idle power draw will be lesser than NVIDIA's reference design. This particular PCB in the pictures holds just six memory chips, indicating it's a 768 MB variant, but there's room for 8 chips, and a 1 GB variant built on this PCB design. We will hear more about this PCB in the weeks to come.
