What Is the TDP of the Core i3-10300?
The Core i3-10300 has a TDP of 65 watts.
This TDP means that the 10300 CPU will consume a maximum of 65 watts of power (PL1) at its max base frequency of 3.70 GHz.
The Core i3-10300 can reach 90 watts (PL2) when reaching the 4.40 GHz max turbo frequency.
The TDP of the Core i3-10300 processor can also be defined as PL1, which is the effective long-term expected steady-state power consumption of a processor. PL2 is a processor's short-term maximum power draw when the CPU runs at its maximum short-term speed (max turbo frequency).
Intel CPU specifications indicate this power dissipation number as "Processor Base Power."
TDP of the Core i3-10300 vs. Other CPUs
The following chart, which we created, compares the TDP ratings of the Intel Core i3-10300 with that of other popular CPUs on the market. This data helps determine CPU energy efficiency. It's important to note that TDP isn't a direct measure of a CPU's average power consumption. However, it remains a valuable metric for comparing similar processors.
What Is TDP?
Thermal Design Power (TDP) is a unit expressed in watts, indicating the maximum heat a cooling system, such as a heatsink or fan, must dissipate. It serves as a crucial parameter for ensuring a system operates within safe temperature limits. The base TDP represents the power consumption of a CPU during typical operations at its base frequency, while the turbo boost TDP (PL2) signifies the peak power consumption when the CPU operates at its highest turbo frequencies. Under lighter workloads, the CPU's power consumption typically drops below the base TDP, enhancing efficiency. Designing a system around the turbo boost TDP ensures it can manage the highest theoretical workload without exceeding its specifications, thus maintaining performance and reliability.
The importance of TDP in CPU performance lies in its role in determining the appropriate cooler required for the CPU to function correctly. If the cooler is undersized or inadequate, the CPU will throttle its performance to prevent damage from overheating.
Factors that affect the TDP of CPUs like the Intel Core i3-10300 include the CPU's frequency, the number of cores, and the voltage required to run the CPU. Turbo boosting, overclocking, or underclocking can all affect the effective TDP of the CPU.
Importance of TDP for System Builders
For system builders, understanding the TDP of a CPU, such as the Intel Core i3-10300, is crucial when selecting the appropriate CPU cooler. A CPU with a high TDP demands a more robust cooling solution, such as a liquid cooling system, to prevent overheating. On the other hand, a CPU with a lower TDP may be effectively cooled by a simpler air cooler. Read more about CPU coolers
below, along with our recommended coolers.
In addition to selecting the right CPU cooler, system builders must also choose a suitable power supply (PSU). A PSU with sufficient wattage is essential to accommodate the CPU's maximum power consumption, which is determined by its TDP, ensuring stable operation. Learn more about power supplies and our top recommendations below.
From my experience as a system builder, I can attest to the significance of proper airflow and case design. Ensuring adequate airflow and directing it efficiently through a well-designed case are vital for maintaining optimal CPU temperatures. While airflow is necessary to dissipate the heat generated by the CPU, a well-designed case ensures that this airflow is effectively utilized where it is needed most.

Choosing a Power Supply for the 10300 CPU Based on TDP
When building a system with a CPU such as the Intel Core i3-10300, it's crucial to select a suitable power supply to ensure that the CPU operates correctly and stably. The power supply must provide sufficient power to the system components, including the CPU, without running out of power or causing system instability.
The TDP of the Core i3-10300 is an excellent way to determine the power supply's wattage requirement. The TDP indicates the CPU's power to draw under a heavy load at its max base speed. Too low of a wattage rating in a power supply can result in power throttling, which can cause the CPU to slow down, impacting performance. It's also important to note that the TDP only represents the CPU's power consumption, and other components, such as the graphics card, RAM, and storage devices, also require power.
The Core i3-10300 has a base TDP of 65 watts. When the Core i3-10300 is turbo boosting it can use up to 90 watts, which means that the power supply should be rated to deliver at least 90 watts to the CPU alone.
When selecting a power supply, it's important to consider factors such as efficiency, reliability, and noise levels. A high-quality power supply with a high-efficiency rating will provide stable power, save energy, and reduce heat generation. From my experience with various power supplies, I can confirm that a high 80 PLUS efficiency rating significantly lowers energy consumption, heat output, and power costs, depending on usage patterns. Selecting a reliable PSU from a reputable manufacturer ensures smooth, long-term system operation without hardware issues.

Choosing a Cooler for the 10300 CPU Based on TDP
When it comes to choosing the best CPU cooler for the Intel Core i3-10300 CPU, it is essential to consider the TDP of the processor. TDP refers to the maximum heat a CPU generates under typical operating conditions. CPUs with a higher TDP tend to be more powerful and require a more robust CPU cooler to prevent overheating, thermal throttling, reduced system performance, and even permanent damage to the CPU.
Regarding cooling the Core i3-10300, there are two main types to choose from: air cooling and liquid cooling. Air cooling is the most common method and utilizes a combination of a heatsink and fan to dissipate heat from the CPU. Air coolers are available in various sizes and sleek designs, with larger models generally providing enhanced cooling performance. However, they can be noisy and bulky, which can be a concern for some users.
On the other hand, liquid cooling circulates a liquid coolant through a network of pipes and a radiator to extract heat from the CPU. While liquid coolers tend to be more expensive than air coolers, they deliver superior cooling performance and are typically quieter. Additionally, liquid coolers are available in both all-in-one (AIO) and custom loop configurations, making AIO systems more convenient for installation.
When selecting a CPU cooler for the Core i3-10300 CPU, choosing one with a high enough TDP rating to handle the processor's thermal output is essential. Ideally, the cooler should have a TDP rating equal to or greater than the CPU's turbo boost TDP (PL2). Additionally, it should be compatible with the motherboard's socket type and fit within the case dimensions.
For reference, the Core i3-10300 has a TDP of 65 watts and when turbo boosting it has a TDP of up to 90 watts.

Choosing a PC Case for the 10300 CPU Based on TDP
When selecting a computer case for a Intel Core i3-10300 CPU, it's important to consider the CPU's thermal design power (TDP), which indicates the amount of heat the CPU can generate under load. The higher the TDP of the CPU, the more heat it will produce, and the more crucial proper airflow becomes.
A computer case with effective airflow is essential for dissipating heat from the CPU and other components, such as the graphics card and power supply. This airflow can be achieved through various methods, including the number and placement of case fans, the size and location of vents or mesh panels, and the use of liquid coolers.
In addition to airflow, the case's design plays a crucial role in cooling performance. In my experience, upgrading to a case with better fan placement, larger vents, and effective cable management significantly improved my system's thermal performance. A well-designed case ensures that airflow is directed to where it is needed most, such as over the CPU and other critical components. Additionally, the case should provide enough space to accommodate large heatsinks or liquid cooling radiators if required, and include cable management options to reduce clutter and enhance airflow.
