AMD Ryzen 7 8700G power: TDP, peak draw & cooling
The AMD Ryzen 7 8700G has a base power (Default TDP) of 65 W. AMD does not publish a peak figure for this processor, so the ~88 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 65 W Default TDP is AMD's own published figure. The 88 W peak is not — AMD publishes no peak power for this processor, so we calculate one. It is a best-effort estimate, not a verified value.
Estimated peak draw
~88 W
Our estimate — AMD publishes no peak figure for this processor.
Default TDP
65 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 modest single-tower air cooler is plenty.
Base power vs peak
Default 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
AMD publishes a Default TDP of 65 W for this processor but does not publish a PPT figure for it — the AMD Processor Specifications database has no PPT field at all, and the product page lists Default TDP only. The ceiling shown here is AMD's own socket relationship applied to that TDP: 65 W x 1.35 = 88 W.
Worth knowing
APU with integrated Radeon 780M graphics. AM5 Phoenix, 65W TDP; AM5 65W class PPT is 88W.

Frequently asked questions
How much power does the AMD Ryzen 7 8700G use?
Its Default TDP is 65 W, which the manufacturer publishes. It does not publish a peak figure for this processor, so the ~88 W shown here is ours, not theirs — AMD publishes a Default TDP of 65 W for this processor but does not publish a PPT figure for it — the AMD Processor Specifications database has no PPT field at all, and the product page lists Default TDP only. The ceiling shown here is AMD's own socket relationship applied to that TDP: 65 W x 1.35 = 88 W. Size cooling and power delivery for the estimate, but treat it as an estimate.
What cooler does the AMD Ryzen 7 8700G need?
A modest single-tower air cooler is plenty. This is a general guideline derived from the ~88 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 AMD Ryzen 7 8700G add to a PSU estimate?
For power-supply sizing we count the CPU at our estimated 88 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.
