I'm building my first PC and would appreciate a compatibility check before buying anything. I've researched the parts and used an AI assistant to help choose components that are available locally in Morocco. My budget is roughly €2,500, and the system will mainly be used for 1440p gaming and recording. Performance and long-term durability are my priorities.
The proposed build is:
CPU: AMD Ryzen 7 7800X3D (tray)
CPU cooler: DeepCool AK620 Digital
Motherboard: MSI B850 Gaming Plus WiFi6E
Memory: 2x16GB Samsung DDR5-5600
Graphics card: ASRock Radeon RX 9070 XT Challenger 16GB
Storage: Samsung 990 EVO Plus 1TB NVMe
Power supply: Corsair RM750e (2025) 750W Gold
Case: NZXT H5 Flow (2024)
Case fans: 2x Arctic P14 Pro 140mm as front intake
Availability is a major limitation here. Many common parts, including reasonably priced B650 boards, boxed 7800X3D processors, memory kits, and SSDs, are either unavailable or heavily marked up. I'm considering an ASUS TUF 850W Gold power supply instead of the 750W model. Are there any compatibility problems or weak points I should address?

The build is broadly compatible, but there are a few things worth checking. If a boxed 7800X3D is unavailable, the tray version may be the practical choice, though you should confirm exactly what warranty the retailer provides. For memory, DDR5-6000 would usually be a better target for this platform if you can find it at a sensible price; the brand matters less than the speed, timings, and having a matched 2x16GB kit.
Also check the exact specifications of the MSI B850 Gaming Plus WiFi6E. That version may not include the same PCIe 5.0 graphics-slot support as the standard WiFi model, so don’t assume the two boards differ only in wireless features. If a B650 board is unavailable or costs more locally, the B850 board can still be perfectly usable, but verify its expansion-slot layout and pricing.
The Samsung SSD should work, although other reputable 1TB NVMe drives may offer similar real-world performance for less. The AK620 is sufficient for the 7800X3D, and the case with two front intake fans should provide decent airflow. Just make sure the motherboard supports the processor with its installed BIOS version and confirm the graphics card fits comfortably in the case.
Local pricing changes the recommendations quite a bit. If the tray CPU, B850 board, Samsung memory, and SSD are the only realistically available options, I wouldn’t reject the build over those parts. I’d mainly verify the retailer warranty, use a matched memory kit if possible, and spend extra attention on getting a high-quality power supply.
