What's the Best PSU to Pair with a 9950X3D and RTX 4090?

I'm upgrading my PC and I'm stuck deciding between a 1000W and a 1200W power supply. I've heard that going with a 1000W might limit the performance of the RTX 4090. Is that true? Would I be better off with a higher wattage PSU?

Going with 1.2kW is a wise move just to be on the safe side. Better to have a bit more power than you need than to risk limiting performance.

Honestly, I'd recommend the Montech Century II 1200W if you're looking for extra safety. It’s a solid choice to ensure you have plenty of headroom for your system!

Either a 1000W or a 1200W PSU is fine as long as you choose a reputable brand. Brands like Seasonic and Corsair are known for their quality, so I’d stick with those.

You won't have any issues running the 4090 with a 1000W PSU! In fact, I have a 14900K and a 4090 on mine, and I've only hit around 900W during stress tests. Your AMD CPU uses even less power. Just make sure to get a high-quality PSU—looking for platinum or titanium rating is a good call. If you're interested, a digital PSU could give you some cool metrics too!
