The PC Power Supply Calculator is a valuable tool designed to help users determine the appropriate power supply unit (PSU) needed for their computer build. By inputting the power consumption values of various components such as the motherboard, CPU, GPU, RAM, storage devices, and other components, along with the efficiency of the PSU, users can quickly calculate the total power requirement for their system.
Formula of PC Power Supply Calculator
The formula used by the PC Power Supply Calculator is as follows:
Power = (MotherboardPower + CPU_Power + GPU_Power + RAM_Power + Storage_Power + Other_Power) * Efficiency / 100
Where:
- MotherboardPower: Power consumption of the motherboard (in watts).
- CPU_Power: Power consumption of the CPU (in watts).
- GPU_Power: Power consumption of the GPU (in watts).
- RAM_Power: Power consumption of the RAM (in watts).
- Storage_Power: Power consumption of the storage devices (in watts).
- Other_Power: Power consumption of other components (in watts).
- Efficiency: Efficiency of the power supply unit (PSU) expressed as a percentage.
This formula takes into account the power requirements of each component and adjusts for the efficiency of the PSU to provide an accurate estimation of the total power needed.

This table provides a quick reference for users to understand the terms used in the formula and their respective descriptions.
Example of PC Power Supply Calculator
Let’s consider an example to demonstrate how the PC Power Supply Calculator works:
Suppose we have the following power consumption values:
- Motherboard Power: 50W
- CPU Power: 100W
- GPU Power: 150W
- RAM Power: 20W
- Storage Power: 30W
- Other Components Power: 50W
- Efficiency: 90%
Using the formula mentioned earlier, we can calculate the total power requirement:
Power = (50 + 100 + 150 + 20 + 30 + 50) * 90 / 100 = (400) * 0.90 = 360 Watts
So, in this example, a power supply unit capable of delivering at least 360 Watts would be required for the computer build.
Most Common FAQs
A: Choosing the right power supply unit ensures stable and reliable performance of your computer system. An insufficient PSU can lead to system instability, crashes, and potentially damage to components.
A: The power consumption values are typically provided in the specifications of the components by the manufacturer. Alternatively, you can use online resources or tools to estimate power consumption based on the component’s model.
A: If you’re unsure about the efficiency rating of your power supply unit, you can refer to the documentation provided by the manufacturer or look for the 80 Plus certification label, which indicates the PSU’s efficiency rating.
A: Yes, the PC Power Supply Calculator is versatile and can be used for various types of computer builds, including gaming PCs, workstations, and general-purpose desktops.
A: In addition to power requirements, factors such as modular vs. non-modular design, certification, brand reputation, and warranty should also be taken into account when choosing a PSU.
