Remember: A high-quality 750W PSU will outperform a garbage 1200W PSU every single time. Calculate carefully, buy from a reputable brand, and your PC will have stable, clean power for a decade. The heartbeat of your machine depends on it.
Then, add 100W to that result for future upgrades and capacitor aging.
In the world of PC building, we obsess over the CPU core count, the GPU teraflops, and the RGB color spectrum. Yet, the component that literally powers this entire ecosystem is often the most misunderstood and overlooked: the Power Supply Unit (PSU). Buying a PSU isn't like buying a hard drive; you cannot simply grab the cheapest unit with the highest advertised wattage. An oversized unit wastes electricity; an undersized unit leads to crashes, data corruption, and even component-destroying fires.
(CPU Max Draw + GPU Max Draw + 100W for system) × 1.5 = Ideal PSU Wattage
