Intel Core i9-9900K power: TDP, peak draw & cooling
The Intel Core i9-9900K has a base power (TDP) of 95 W. Intel does not publish a peak figure for this processor, so the ~119 W below is our own estimate rather than a vendor ceiling. Size cooling and power delivery for it, but treat it as an estimate.
Recommendations are planning estimates, not electrical or purchasing advice. The hardware figures behind them are vendor-published; your exact board-partner model and build can still differ.
The 95 W TDP is Intel's own published figure. The 119 W peak is not — Intel publishes no peak power for this processor, so we calculate one. It is a best-effort estimate, not a verified value.
Estimated peak draw
~119 W
Our estimate — Intel publishes no peak figure for this processor.
TDP
95 W
Vendor base/rated power — typical sustained draw, not the ceiling.
CPU power connector
1× EPS 12V 8-pin
Fed from the motherboard's EPS 12V connector, not directly from a PSU cable to the CPU.
Cooling class
Guideline
A good dual-tower air cooler or a 240 mm AIO handles it comfortably.
Base power vs peak
TDP describes typical sustained operation; Estimated peak draw is the ceiling the chip can pull under a heavy all-core workload. Cooling and VRM headroom should be planned around the peak, while everyday power use sits closer to the base figure.
Where the peak figure comes from
Intel published a single TDP of 95 W for this processor and no Maximum Turbo Power — that figure was not introduced until 12th gen, and this part's ARK page has a TDP row only. The ceiling shown applies Intel's default PL2 relationship to the TDP: 95 W x 1.25 = 119 W. Real boards routinely raise or remove that limit, so treat it as a floor for sizing rather than a hard ceiling.
Worth knowing
Base power (PBP) verified via Intel ARK; Intel does not publish a Maximum Turbo Power for this generation on ARK, so the peak (PL2) value is not officially re-verified.

How to check this figure
Intel ARK still lists this processor — the page is live, marked Discontinued, launched Q4'18. Its power row is headed "TDP", not "Processor Base Power": Intel renamed the field and added Maximum Turbo Power with 12th gen, so there is no MTP row here to read. If you want to confirm the field really is absent rather than missed, open any Core Ultra part (the 285K, say) and compare — that page shows both Processor Base Power and Maximum Turbo Power.

Frequently asked questions
How much power does the Intel Core i9-9900K use?
Its TDP is 95 W, which the manufacturer publishes. It does not publish a peak figure for this processor, so the ~119 W shown here is ours, not theirs — Intel published a single TDP of 95 W for this processor and no Maximum Turbo Power — that figure was not introduced until 12th gen, and this part's ARK page has a TDP row only. The ceiling shown applies Intel's default PL2 relationship to the TDP: 95 W x 1.25 = 119 W. Real boards routinely raise or remove that limit, so treat it as a floor for sizing rather than a hard ceiling. Size cooling and power delivery for the estimate, but treat it as an estimate.
What cooler does the Intel Core i9-9900K need?
A good dual-tower air cooler or a 240 mm AIO handles it comfortably. This is a general guideline derived from the ~119 W peak, not a specific product recommendation — a chip's real thermals also depend on the board, case airflow, and how hard you push it.
How much does the Intel Core i9-9900K add to a PSU estimate?
For power-supply sizing we count the CPU at our estimated 119 W peak — a conservative figure so the supply is not undersized. Add your graphics card and the rest of the system in the PSU calculator for a full recommendation.
