Are These Parts Compatible for My First Mini-ITX Gaming PC Build?

Asked by MellowBirch47
I'm putting together my first mini-ITX gaming PC and plan to reuse the Ryzen 5 7600, 32GB of DDR5-6000 memory, and one 1TB NVMe SSD from my current computer. The new build uses an ASRock B850I Lightning WiFi motherboard, a Thermalright AXP90-X47 low-profile cooler, a second 1TB Crucial P3 Plus SSD, an RTX 4070 SUPER, a Fractal Design Terra case, and an 850W Corsair SFX power supply. I'm also planning to run two 1440p 200Hz monitors. Are there any compatibility or performance concerns that PC Part Picker might miss, particularly with cooling, dimensions, storage, or power? What other tools or websites are useful for checking a build? All prices are in Australian dollars.

The Terraโ€™s limited CPU-cooler clearance can hold back sustained CPU performance and leaves you with fewer upgrade options later. A slightly taller case such as the Thermaltake TR100 offers room for a 240mm liquid cooler, costs less, and has a similar footprint, although the Terra is a reasonable choice if you prefer its design.

The Crucial P3 Plus has been discontinued and isnโ€™t a particularly strong choice for a new build. Consider a currently available alternative such as the Patriot P300, P320, P400 Lite, or Fanxiang S880, and check reviews and warranty support before purchasing.

The AXP90-X47 looks suitable for the Terra, but the listed price seems high for Australia. It may be worth checking local listings more carefully, since an Australian seller may have the same cooler for considerably less than the imported option.

MellowBirch47: Thanks, Iโ€™ll compare the local listings before buying the cooler.
