Power Supply: Reliable and Efficient
A quality PSU is crucial for system stability and longevity. Don't skimp on this component.
PSU Selection Guide:
- Wattage: 650W for budget, 750W for mid-range, 850W+ for high-end
- Efficiency: 80+ Gold minimum, 80+ Platinum preferred
- Modularity: Semi or fully modular for cleaner builds
- Brand: Seasonic, Corsair, EVGA, be quiet!
Cooling: Keep Your Components Happy
Proper cooling ensures optimal performance and component longevity. Choose between air and liquid cooling based on your needs and budget.
CPU Cooling Options:
Air Cooling
Noctua NH-D15, be quiet! Dark Rock Pro 4, Cooler Master Hyper 212
Pros: Reliable, quiet, no maintenance | Cons: Large size, limited overclocking
Liquid Cooling (AIO)
Corsair H100i, NZXT Kraken X63, Arctic Liquid Freezer II
