Intel Nova Lake-S Could Draw 474W: Is a High-End PC Still Practical to Run at Home

Rising power draw on flagship CPUs and GPUs has become a recurring theme with each new hardware generation, and a new leak suggests Intel's next flagship desktop chip could push that trend even further.

According to a leak from LC Tech Leaks, backed by a known Intel leaker, Intel's top-end Nova Lake-S desktop chip could feature 52 cores, reportedly arranged as 16 performance cores and 32 efficiency cores, and pull up to 474W of PL2 power.

The 474W figure refers to PL2, the short-term boost limit a CPU can reach while turboing, rather than idle or light-use power draw. According to the leak, this figure applies to the flagship dual-tile model running at stock settings, with overclocking likely to push the draw even higher.

For reference, Intel's flagship desktop chips have generally sat around 250W since 10th-generation Comet Lake, making a jump to 474W a significant increase over recent generations.

Motherboard Photos Suggest Extra Power Connectors

The leak also points to high-end LGA1954 motherboards, likely from the Z990 series, potentially featuring three EPS 8-pin CPU power connectors instead of the more typical one or two. One EPS 8-pin connector can handle about 235W, so two of them can handle 470W. The socket itself can handle another 75W, so the leaked 474W number would be met without the need for a third connector at stock settings.

It seems like a third connector would only be useful for overclocking, and it wouldn't change how well the system works when it's not overclocked. It is also worth noting that the motherboard photo circulating with this leak showed two EPS connectors and a PCIe 8-pin connector, rather than three dedicated CPU power connectors.

That approach would make practical sense, since a PCIe connector can still deliver substantial 12-volt power, and modular power supplies are more likely to already include spare PCIe connectors compared to additional EPS connectors, even though many modular power supplies share the same output pins between EPS and PCIe cables.

Nova Lake will require a new socket with no upgrade path.

Nova Lake is rumored to require the new LGA1954 socket paired with 900-series chipsets, meaning there will be no upgrade path from the current LGA1851 socket. Intel has not officially confirmed any details from this leak, including the core count, power figures, socket requirements, or motherboard power delivery design.

If this leak is true, it fits with a larger trend of flagship CPUs and GPUs using more power with each generation. This makes me wonder if high-end PCs can still be used in a normal room without special cooling or airflow.

Systems that use this much power can make the room warmer after a while, especially if there isn't enough movement, air conditioning, or an open window nearby. This is something that should be thought about just as much for comfort as raw performance numbers.
