Have you ever been confused about how much wattage your power supply should have when building a DIY PC? This is where a PSU wattage calculator comes in handy. It accurately estimates your components' power consumption and recommends an appropriate power supply to prevent underpowering or wasting electricity.In addition to the previously recommended OuterVision calculator, brands like Be Quiet, FSP, and Seasonic also offer PSU wattage calculators in both Chinese and English.| How to Use a PSU Wattage Calculator |Using the FSP Wattage Calculator as an example, let's calculate power consumption based on the following configuration:CPU: Intel Core i7-13700KCPU Cooler: 1 water block, 3 fansRAM: 16GB DDR4 x 2GPU: Nvidia GeForce RTX 4070 TiStorage: M.2 SSD x 2Fans: 4 additional case fans| Step-by-Step Guide |Step 1: Select Your CPU ModelChoose the brand (e.g., Intel or AMD).Select the socket type of your processor.Pick the exact CPU model and indicate if overclocking is enabled.Step 2: Select Your GPU ModelChoose the GPU brand and model.Specify the number of GPUs installed.Indicate whether overclocking is enabled.Step 3: Choose RAM, Storage, and Cooling SystemRAM: Enter the number of memory sticks and type.Storage: Specify the number of installed storage drives. (M.2 SSDs are often excluded from this calculation.)Cooling: Enter the number of fans and the size of any liquid cooling system.Step 4: Calculate and Review the ResultsAfter inputting all the details, click the Calculate button. Based on this setup, the FSP Wattage Calculator estimates the system's power consumption at 650W and recommends a 750W power supply.| Why Do Different Wattage Calculators Provide Different Results? |When testing the same configuration on different PSU wattage calculators, the recommended wattage may vary:FSP Wattage Calculator: Recommends 750W+ PSUBe Quiet Wattage Calculator: Recommends 1000W PSUMSI Wattage Calculator: Recommends 850W+ PSUOuterVision Wattage Calculator: Recommends 750W+ PSUThis discrepancy is normal because different calculators use slightly different formulas for estimation.How to Choose the Right Wattage?Based on these results, it’s recommended to choose a PSU between 850W and 1000W:If you're on a budget, a minimum of 850W should suffice.If you plan to upgrade your system in the future, opting for a 1000W PSU might be a better investment.

What to look for in a 400W–650W power supply When choosing your base-wattage power supply, explore the following specs: Continuous power rating: All the power supplies on this page will be 650 watts or less. Size and form factor: All PSUs on this page are ATX, but compare that against the possibility of getting a smaller SFX unit. Modularity and connectivity: Consider the ports you need and whether you want a fully modular or semi-modular power supply. Efficiency scores: You can filter amongst 80 Plus and Cybenetics ratings. Can power supplies up to 650 watts handle modern gaming and high-end GPUs? If you’re looking to take the conservative approach when buying a power supply unit for your PC, then the first question should be “is it going to be enough for your build?” The answer really comes down to what the components are inside your PC build. To determine if a lower-wattage PSU is enough, add up all the power draws of your components for your build. If that number is lower than the continuous power rating of the PSU then it’ll likely run. But also be sure to build in at least 25% headroom to keep your PSU running efficiently. Not sure which PSU is right for your setup?
