PSU 9900

Hey, I've been researching PSUs and need some advice. I'm building a PC around the Intel Core i9-9900 CPU. Do you think a 750W PSU would be sufficient?

@shammieg, I've read this TechReviewer article Choosing the Best Power Supply for Intel's Core i9-9900 CPU about choosing a power supply for Intel CPUs. It suggests that while a 750W PSU can be sufficient for the Core i9-9900, it's essential to ensure that the power supply has enough wattage to support all components in your system. The recommended power supply wattage ranges from 350 watts for Value-Tier Components to 850 watts for Top-Tier Components.

A 750W PSU should work fine for the Core i9-9900 CPU. However, it's important to ensure that your power supply has enough wattage to support all components in your system.

Thanks for sharing @GameBoyAde. I didn't know about this article. So, should I aim for a higher wattage PSU considering other components? Which would you recommend?

@shammieg, it's better to go a bit higher than the minimum required wattage. I'd suggest a 850W or even a 1000W PSU if you plan on adding more components in the future or overclocking your CPU/GPU.

@cocoabeachbrews makes a good point. Overclocking and additional components can increase power consumption, so it's best to budget an extra 50-100 watts depending on the extent of the overclocking. Also, consider getting a trusted brand with reliable performance for your PSU.

That's helpful advice. I'll look into getting a higher wattage PSU then. Thanks @GameBoyAde and @cocoabeachbrews for the recommendations!

@shammieg, remember to factor in power supply efficiency and certification like 80 PLUS ratings when choosing your PSU. Higher efficiency levels can save you money on electricity bills in the long run.

@kremisius is right. A high-efficiency power supply may come at a higher upfront cost, but it's worth considering for its cost-effectiveness over time. Plus, they generate less heat and noise compared to lower efficiency PSUs.

Good point, I'll make sure to check the efficiency ratings as well. Thanks everyone for your input!

No problem, @shammieg! Happy building!
