I'm currently equipped with a 750W power supply and I'm considering an upgrade to a 9800X3D and an RTX 5080. Do I need to invest in an 850W or even a 1000W PSU, or would my 750W unit be adequate for this setup?

I personally opted for an 850W PSU just to be safe. The 50 series GPUs can experience significant power spikes, sometimes nearly doubling their rated consumption. It might be worth it to go a bit bigger to avoid any potential issues down the line.
If you're looking for longevity, I’d suggest buying a 1000W PSU. It's only a bit more investment now and gives you great headroom for any future upgrades or hardware changes.
You could get away with a 750W, but it definitely might be cutting it close. If you're planning on running intensive applications or gaming at high settings, I'd strongly recommend at least an 850W PSU for peace of mind. My PC runs fine on an 850W with similar components, so I feel it's a safer bet.
Better to be safe than sorry, right? I’d rather not risk shutting down during a gaming session!
In my experience, you can run the RTX 5080 and 9800X3D on a 750W PSU with no issues, but I did have to swap mine after experiencing random shutdowns with demanding games. A slight undervolt on the GPU also helped stabilize things for me.
Yes, a 750W PSU should be sufficient for your setup, provided it's a high-quality unit. However, it's a good idea to consider getting a bigger PSU for future upgrades since a PSU is a long-term investment. Typically, your setup will draw no more than 600W, leaving you a solid buffer for any transient spikes.
That makes sense! It’s always better to have a little extra just in case.
Isn’t that what the excursion testing is for? I thought a good PSU could handle those spikes.
