I'm building my first gaming PC and don't know much about choosing parts. My budget is about $2,100 USD, and I mainly want to play games. Could you point out any incompatible parts, unnecessary expenses, or better alternatives?
Current parts:
- CPU: AMD Ryzen 7 5800X3D
- CPU cooler: Thermalright Royal Pretor 130 Ultra
- Motherboard: Asus TUF Gaming B550-Plus WiFi II ATX AM4
- Memory: Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3200 CL16
- Storage: Silicon Power UD90 1 TB PCIe 4.0 NVMe SSD
- Graphics card: Gigabyte Windforce OC GeForce RTX 4070 12 GB
- Case: Fractal Design North ATX
- Power supply: be quiet! Dark Power 13 1000 W
- Operating system: Windows 11 Home
I originally considered a Ryzen 7 9800X3D, but I understand that it requires an AM5 motherboard and DDR5 memory, unlike the AM4 motherboard and DDR4 RAM in this list.

The listed B550 board is a solid option and provides the features needed for the AM4 build, including multiple NVMe slots. Just remember that the 9800X3D and DDR4 combination cannot be used with it; choose either the 5800X3D with this board and memory, or move the whole platform to AM5 with DDR5.
With a budget around $2,100, it makes sense to consider the newer AM5 platform rather than investing in AM4. A Ryzen 7 9800X3D paired with a B650 motherboard and 32 GB of DDR5 could be a strong gaming setup with a better upgrade path. The RTX 4070 is still capable, but looking at newer or used graphics cards may let you get more gaming performance for the money.
The 1,000-watt power supply is more than this system needs. An excellent 750–850 W unit should be plenty for a Ryzen 7 5800X3D and RTX 4070, including normal power spikes. Keeping the larger unit is not inherently harmful, but it may be an unnecessary place to spend part of the budget.
The Ryzen 7 9800X3D is not compatible with this build because it uses the AM5 socket and requires DDR5 memory. A B650 motherboard or another AM5 board would be appropriate for that CPU. The Ryzen 7 5800X3D does work with the B550 motherboard and DDR4 RAM, although you should confirm that the motherboard BIOS supports it. A compatibility checker such as PCPartPicker can help catch socket, memory, and clearance issues.
I chose the parts by looking at recommendations because I’m new to PC building. I was considering the 5800X3D after realizing the original CPU didn’t match the motherboard. I’ll use a compatibility checker before buying.
Thanks for pointing that out. I wasn’t familiar with power spikes or how much headroom the system actually needs, so I’ll compare quality 750–850 W options instead.
