Intel Z790, Z990 Flagship Chipsets Consume 14W at Peak; Nova Lake Motherboards Shrink PCH by 22%

Intel's upcoming Z790 and Z990 flagship consumer chipsets will run up to 14W peak power consumption, driven by increased PCIe 5.0 lane density and feature integration. Tom's Hardware reports Nova Lake motherboards will feature a PCH 22% smaller than Z890 predecessors, improving board-level efficiency.

Smaller PCH footprint alongside moderate TDP signals Intel's focus on power-density optimization as chip complexity grows. The moves support enthusiast and workstation segments where thermal headroom and board area are premium.
