Intel's upcoming "Nova Lake-S" processor will consume up to 474 W in PL2 mode, according to leaked specifications confirmed by Intel insider Jaykihn. This 52-core overclocking variant represents the highest power envelope Intel has shipped for consumer desktop chips, surpassing typical high-end desktop designs. The extreme power draw reflects Intel's push toward higher core counts for enthusiast users.

The Z990 platform reference motherboard now supports three 8-pin CPU power connectors, a departure from the usual dual-connector setup found on enthusiast boards. ASUS, MSI, GIGABYTE, and ASRock will receive these reference designs for their upcoming motherboards. While all Z990 boards support 44-core and 52-core processors at 175 W, the triple-connector configuration targets overclocking-focused models requiring additional headroom.

Intel employs a tiled approach with dual compute dies connected to an SoC tile, similar to AMD's strategy. Single-tile configurations max out at 28 cores, while dual-tile SKUs reach 52 cores. Both compute tiles maintain equal access to memory and PCIe lanes, enabling Intel to scale core counts dramatically within the consumer platform.

This power-hungry design signals Intel's response to AMD's high-core-count Ryzen processors, though it demands significantly more robust cooling and power delivery. Enthusiasts building premium systems will need to plan for substantially higher PSU requirements and thermal solutions.
