I'm putting together my first PC and would appreciate some feedback before buying the parts. The build includes a Ryzen 7 7800X3D, Thermalright Phantom Spirit 120 SE, Asus ROG STRIX B850-A motherboard, 32 GB of DDR5-6000 CL30 memory, a 1 TB Samsung 990 Pro NVMe SSD, an Asus RX 9070 XT, an NZXT H5 Flow case, a 750W MSI MAG A750GL Gold modular power supply, Windows 11 Home, and five additional Arctic P12 Pro fans. I mainly play Zenless Zone Zero and Wuthering Waves, along with watching videos and browsing the internet. I'd like to play at fairly high settings with smooth performance, but I'm not sure what resolution or refresh rate I'll be using yet. The build is already slightly over budget, so I'm wondering whether it's unnecessarily powerful and which components could be downgraded without hurting gaming performance too much.

The 750W supply should run this hardware, but an 850W unit would give you more breathing room for future upgrades. It can also run more quietly because the PSU fan usually doesn’t ramp up as much when the system is using a smaller percentage of its capacity. Look for a well-reviewed 850W Gold model with the proper modern GPU power connector, and compare noise and efficiency tests rather than choosing solely by wattage.
The parts are not inherently mismatched, but the build is definitely on the powerful side for your stated games. You could first look for savings on the motherboard, SSD, extra fans, and Windows rather than immediately downgrading the CPU or GPU. A less expensive B650 or B850 board, a good 1TB PCIe 4.0 SSD that isn’t a flagship model, and fewer case fans may provide similar real-world results. The included case fans and the Phantom Spirit cooler should already be enough for a well-ventilated setup.
I’d prefer to keep enough performance for smooth high settings, so saving money on the motherboard, storage, or cooling sounds better than reducing the graphics card too much.
The CPU and RX 9070 XT are probably more performance than you need for these games, especially if you’re playing at 1080p or using a lower-refresh display. Before cutting parts, decide whether your target is 1080p, 1440p, or 4K and what refresh rate you want. For smooth high settings at 1440p, the build is reasonable, but at 1080p you could likely save money with a less powerful graphics card and possibly a cheaper CPU.
I’m not sure what resolution I’ll use yet. My current computer started freezing and eventually stopped booting from an SSD problem, and it also struggled to run Wuthering Waves smoothly. I mainly want the new system to handle it reliably at fairly high settings.
You may not need to buy a full retail Windows license as part of the initial build. You can install Windows and activate it later, or compare legitimate lower-cost licensing options. That could free up some of the budget without changing the hardware.

That makes sense. I’ll compare some 850W options and see whether I can find one that fits the budget.
