<p>At NVIDIA GTC 2025, we got to tour Pegatron's booth, where we saw the Pegatron NVIDIA GB300 NVL72 rack and other GPU systems. The GB300 NVL72 racks are liquid cooled with a busbar for power in the rear. The sleds have four Blackwell modules along with two NVIDIA Grace CPUs and are liquid cooled.</p><p>The article also mentions that Pegatron is integrating Delta power supply shelves into their racks and that the NVIDIA GB300 NVL72 is neat, with several other GPU systems on display.</p>
