Future Intel Nova Lake-S (Core Ultra 400) processors, especially the flagship 52-core models, will require serious power delivery. Only high-end Intel 900-series motherboards will be able to fully support them.
Nova Lake will introduce major changes for Intel in both core count and power consumption. The top configuration is expected to include 16 performance cores (P-cores), 32 efficiency cores (E-cores), and 4 LP-E cores, using a “dual compute tile” design that promises a significant performance boost.
However, this power comes at a cost. Reports suggest that under PL2 limits, dual compute tile chips could reach nearly 500W of power consumption.
Z990 And W980 Chipsets Will Be Essential
To run the top Nova Lake processors at full power, a very robust VRM (voltage regulation module) design will be required. While the Intel 900 chipset family is expected to include models like the B960 and Z970, only the flagship Z990 and the workstation-focused W980 chipsets are expected to fully unlock the 52-core model’s potential.
Entry-level and mid-range motherboards may still be physically compatible thanks to the new LGA 1954 socket, but they will likely limit clock speeds or power limits such as PL2 and PL4 to prevent overheating and stress on their power circuits.
Enthusiasts planning to adopt these high-end Nova Lake CPUs will need more than just an expensive motherboard. Power supplies rated above 1500W may be necessary, along with advanced liquid cooling systems to handle the extreme heat output when these processors run at full load.
Intel’s Nova Lake platform is expected to launch toward the end of 2026, marking one of the most power-hungry and ambitious desktop generations the company has released.
