NVIDIA seems to have lifted restrictions over manufacturers coming up with their own designs for the GeForce GTX 285 accelerator, barely a month into its market introduction. Zotac, backed by the engineering prowess of PCPartner seems to have already designed their custom-PCB according to a finding by Expreview. The new PCB employs a decent bit of component rearrangement.

Perhaps the most significant part of that rearrangement comes from moving the vMem circuit that powers the card's 16 memory chips to its anterior end, in between the NVIO2 processor and the SLI connectors. The PCB uses a new MOSFET arrangement that groups them in a DPAK group. The vGPU circuit consists of 6 phases, and the vMem circuit 2. Zotac makes use of an aluminum support-brace around the G200b graphics processor, which serves as a safety measure for the GPU, minimizing the impact of PCB bending on the fragile ball-grid, especially with 55nm GeForce GTX 260 and GTX 285 lacking a back-plate that counters PCB bending. The orange-coloured DVI connectors make it distinctively Zotac. The SKU based on the new PCB may feature reference clock speeds of 648/2484/1476 MHz (core/memory/shader). Its cooler design remains unknown.
