Welcome to the Corsair Power Supplies collection. With 45 PSUs in stock, priced from $10 to $98.88, we have a solution for any system, from budget builds to high-end rigs. Reliability and clean power are critical for stability and longevity.
Use our PSU wattage calculator to determine your needs, and read our guides on modular cable management, efficiency ratings, and compatibility with RTX 4080 and other components.
Power Your Build
Assess your system's total wattage draw (we provide a calculator tip). For a mid-range gaming PC, 650-750W is typical; for RTX 4080 or higher, 850W+ is recommended. Prices range from $10 for basic units to $98 for premium platinum-rated ones. Consider a fully modular PSU for clean cable management. Check compatibility with your case and cable length.
NVIDIA recommends at least 750W for an RTX 4080. To be safe and allow overclocking, choose an 850W or 1000W Corsair PSU, ideally with an ATX 3.0 connector for direct GPU power.
Enter your components (CPU, GPU, drives, etc.) in the online calculator. Add 20% headroom for peace of mind. The calculator suggests a minimum wattage, and you can then pick a Corsair unit above that.
Both are high-end. RMx is a mainstream high-efficiency PSU (Gold), while HX is Platinum-rated with better components and 10-year warranty. HX is designed for heavy overclocking and longer workloads.
