Zotac Beefs-Up GeForce GTX 200 with 15 Phase VRM Design
Armed with a creative engineering department, Zotac is in the news for innovating a new graphics card PCB design every now and then. For NVIDIA's GeForce GTX 200 series alone, the firm developed several performance and value oriented PCB designs. It decided to up the ante with a new single-GPU PCB design that is compatible with all GTX 200 series GPUs from NVIDIA, and is out with a GeForce GTX 260-based model out for the Chinese market. The new PCB focuses on strong power circuitry that allow high stability for overclocking. The 12-layered PCB is jam-packed with high-grade power circuitry, which ensures the GeForce GTX 260 GPU runs at 800 MHz out of the box, with even more overclocking headroom to spare.
To begin with, the vGPU portion consists of a lavish 12-phase digital PWM circuit with Renesas LFPAK MOSFETs, BL high-capacity PWM chokes, and Panasonic SP-CAP, flatbed capacitors and a dedicated VRM controller. The vMem portion has a 3-phase power circuit that uses the same kinds of components as the vGPU, and has its own VRM controller. The PCB draws auxiliary power from PCI-E 8 + 6 pin connectors. It holds place for two more memory chips indicating that the same PCB could be used for a GeForce GTX 285 based SKU in the future. On the outputs front, a DVI-D, HDMI, and D-Sub make for the card's connectivity. The new Zotac GeForce GTX 260 model will be cooled by an Arctic Cooling Accelero Xtreme GTX cooler. It is made exclusive for the Chinese market, with a price of RMB 1399 (US $205). Technical data from its electical-testing can be viewed here.
