I'm putting together my first PC and wanted to get some feedback on the parts I've chosen. Here's what I've got planned:
- **CPU**: AMD Ryzen 9 9900X 4.4 GHz 12-Core Processor
- **Cooler**: Thermalright Peerless Assassin 120 SE 66.17 CFM CPU Cooler
- **Motherboard**: MSI MAG B850 TOMAHAWK MAX WIFI ATX AM5
- **Memory**: G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL36
- **Storage**: Samsung 990 Pro 2 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
- **Graphics Card**: Sapphire NITRO+ Radeon RX 9070 XT 16 GB Video Card
- **Case**: Lian Li LANCOOL 217 ATX Mid Tower
- **PSU**: Corsair RM850x SHIFT 850 W 80+ Gold Certified Fully Modular Side Interface ATX
I'm mainly looking to ensure all these components are compatible. Would really appreciate any thoughts or suggestions!

What’s your main use for the PC? The Ryzen 9 9900X isn’t typically the best choice for gaming—there could be better options out there.
Your build is mostly compatible! If you're focused on gaming, consider the 7800X3D instead of the 9900X—it might give you better performance. Also, while the B850 Tomahawk and 990 PRO are solid, they may be a bit excessive for gaming. Just a heads up, the RMx Shift has its cables coming out of the side, so double-check that with your case layout.
Thanks for the info! What other motherboards would you suggest? Coming from Xbox, I’m always conscious of storage and can probably cut down on that too.

I’m mostly gaming, so I thought the price was decent. Any better alternatives you’d suggest?
