Uses official Intel and AMD power specifications (PBP/MTP/TDP/PPT) for precise calculations rather than third-party estimates.
Tailor your power estimate based on Light, Typical, or Heavy workloads with manufacturer-specific power scaling patterns.
Account for CPU and GPU overclocking with intelligent power scaling based on real-world power consumption patterns.
See exactly how each component contributes to your system's total power consumption with our intuitive visualization.
Our custom PC builds use the same precision engineering approach as this calculator. Every component is meticulously chosen to ensure optimal performance, efficiency, and aesthetics.
Modern CPUs and GPUs can temporarily exceed their rated TDP by up to 50% during boost operations - one reason to select a high-quality PSU with adequate headroom.
