Intel's upcoming Nova Lake series is expected to feature aggressive power specifications, with the flagship 52-core desktop variant targeting a PL2 (Power Limit 2) of 474W during boost periods. Previous leaks suggest a PL4 emergency power ceiling above 700W. The leak, confirmed by reliable hardware sources, reveals Intel's ambition to deliver massive core counts—up to 52 cores with 16 performance and 32 efficiency cores—on a new LGA1954 socket.
High-end motherboards will need to accommodate the power draw. Enthusiast-class Z990 boards are expected to feature three EPS 8-pin CPU power connectors instead of the traditional two, allowing full power delivery for extreme overclocking scenarios. The third connector would be optional for standard rated performance, but signifies the shift in platform requirements. Nova Lake-S will carry the Core Ultra 400S branding and represents Intel's largest desktop CPU overhaul in years.
For system builders and OEMs: these power figures demand robust PSU design and careful thermal planning. A 474W CPU alone requires a 1200W+ system PSU. The announcement also signals Intel's strategy post-Nvidia dominance—maxing out core counts and efficiency to compete in a market where AMD has held clock-per-watt advantages. Expect detailed power management profiles and efficiency/performance tradeoff discussions when detailed specs land.
