ASRock recently introduced their new flagship motherboard. The X299 Taichi XE, LGA 2066 socket for the Core i9 Extreme processors. The motherboard is actually very similar to the X299 Taichi, but a major difference is from a redesigned CPU VRM.
X299 Taichi XE comes with a VRM that offers higher current management and draws power from two 8-pin EPS connectors instead of one, just like in the old X299 Taichi. The EPS connectors are different from the standard power supply connectors used for desktops in homes and offices.
X299 Taichi XE has the EPS connectors, these are a non-ATX standard adopte d by Server System Infrastructure (SSI), that provides stable environment for critical server-based systems and applications. The CPU VRM heatsink is heavier, and offloads some of its heat onto a secondary heatsink using a heat pipe.
Now when it comes to overclocking. Voltage is the foundation, the life blood, on which the hardware operates. Therefore consistent, solid voltage flow is necessary. Including the fact that Robust hardware is crucial to manage and regulate all the power, to the parts, as per need basis.
X299 Taichi XE has kept special consideration to those industrial grade hardware components, such as the CPU VRM and the heat sink. The rear I/O shroud no longer spans the entire length of the board, and shrouds only the I/O, and an aluminum fin-stack heatsink.
Everything else in the X299 Taichi XE remains the same as X299 Taichi, including four PCI-E 3.0 x16 slots, 3 x 32Gb/s M.2 slots, 10 SATA 6 Gb/s, networking that includes Intel-made 802.11ac, Bluetooth 4.2, and gigabit Ethernet controllers; and the onboard audio solution.
The strategy to add a heavier VRM + heatsink is similar to that of the ASUS ROG Strix X299-E versus the X299-XE, where the later has a beefy VRM + heatsink. ASRock may charge a premium on the revised model although prices haven’t been confirmed yet.
