I picked up a DDR5 gaming build at a good price and, after selling the extra parts, I'm left with a 2x16GB G.Skill Trident Z kit rated at 6400 MT/s and CL32. I'd like to build around it, but I'm trying to avoid the power consumption of the original Core i9-13900K setup. A 360mm cooler and a small-form-factor power supply are possible, but a more efficient Ryzen system may offer better value.
I'm considering a Ryzen 7 7800X3D, although my CPU and motherboard budget is about $350 maximum. I only upgraded my current system a couple of weeks ago, so I may still be able to return some of its parts. My current system includes a Ryzen 5 5500X3D, an ASUS Prime B550M WiFi board, 32GB of DDR4-3200 CL16, a Titan Xp, an 850W ATX power supply, and a Lian Li case. I may also be able to reuse hardware from an NZXT H1.
The PC is mainly for gaming and web browsing, and I'm located in Southern California. What CPU and motherboard combination makes the most sense for the DDR5 kit and my budget?

First, decide whether you actually want to move to DDR5. Since you already have the kit and can still return some of the newer DDR4 parts, switching platforms makes sense if the return costs are low. For a roughly $350 CPU-and-board budget, a Ryzen 5 7600 or 7600X paired with an inexpensive B650 motherboard is the realistic route. A 7800X3D is excellent for gaming, but it will usually consume most or all of that budget by itself.
Returning the DDR4 purchases and using the DDR5 kit is probably the best value, assuming the return process doesn’t cost you much. You don’t need an expensive board for a 7600-class processor—look for a reasonably priced B650 model with the features you actually need, such as Wi-Fi and enough M.2 slots. Keep the existing 850W power supply unless its quality or condition is questionable; changing to a small-form-factor PSU is unnecessary unless you are also changing cases.
I’m in the United States, specifically Southern California, so I can shop from the usual local and online retailers.
A Ryzen 5 7600 with a basic B650 board would be a much better fit than trying to force a 7800X3D into a $350 limit. It is efficient, includes a usable stock cooler, and gives you an upgrade path on AM5. The 7600X is fine too, but only choose it if the price difference is small or you already have a cooler. Your DDR5-6400 kit may need to run at 6000 MT/s for the best stability, since many Ryzen systems prefer DDR5-6000 with EXPO.
I mainly game and browse, and I’m in the US. I didn’t mean that I refuse to upgrade again—I just wanted to mention that the current system is only a couple of weeks old.
