Intel’s next desktop chip family is starting to look less like a routine upgrade and more like a small electrical project. New reports say Nova Lake-S, the upcoming Core Ultra 400 lineup, will push as much as 474 W in PL2 on the Z990 platform, with the top-end 52-core models reserved for boards that can handle three 8-pin CPU power connectors.
That is a very different design target from today’s Arrow Lake-S parts, which top out at 24 cores. It also hints at where the real battle is headed: not just raw performance, but whether motherboard makers can keep up without turning every premium desktop into a cable-management crime scene.
Z990 boards are being built for much higher power draw
According to the latest guidance for motherboard vendors, new Z990 boards should be ready for CPUs that can draw up to 474 W in PL2. That lines up with earlier claims that Nova Lake-S would reach 150 W in PL1 and 854 W in PL4, so this does not look like a random leak so much as the next step in Intel’s usual ”more cores, more heat” storyline.
The platform itself is expected to be split into classes for 35 W, 65 W, 125 W, and 175 W processors. Only the high-end Performance models would reportedly get three EPS connectors; the rest of the 900-series boards would stick with the more familiar two-connector setup.
- Nova Lake-S top power in PL2: 474 W
- Earlier reported PL1 for top models: 150 W
- Earlier reported PL4 peak: 854 W
- Top configuration: 52 cores
Gigabyte has already shown a triple-EPS prototype
A prototype from Gigabyte shown at Computex 2026 added some weight to the rumor mill: a motherboard with three 8-pin CPU power connectors and a new LGA 1954 socket, the same socket that has been linked to Nova Lake-S. Vendor demos like that usually arrive before the official product stack is ready, which is Intel’s polite way of making everyone else build the supporting cast first.
Intel has only officially said that Nova Lake desktop chips will arrive in the second half of 2026. But several insiders now point to a possible slip into the first quarter of 2027, with the first wave limited to single-compute-tile models with up to 28 cores. The 52-core flagship would come later, likely in May or June 2027.
The 52-core flagship may be Z990-only
The biggest models are shaping up to be power-gated as much as performance-gated. Reports say the 44-core and 52-core Intel chips will be officially supported only on Z990 motherboards, and that cheaper boards may impose automatic performance limits. That’s a classic segmentation play: enthusiasts get the fast lane, everyone else gets a controlled slip road.
If the leaks hold, Nova Lake-S will be Intel’s clearest attempt yet to answer AMD’s core-count pressure with brute force instead of restraint. The open question is whether buyers want a desktop flagship that needs three EPS connectors, or whether that level of overhead will make even hardcore PC builders pause before reaching for the credit card.
