## Questions & Answers

**Q: How do you get WiFi to this motherboard**
A: Buy a WiFi PCIe Card! You can buy a wifi 6 card for between twenty and forty bucks and they take minutes to fit. If you don't need an ultra-fast and capable wifi connection you can also buy a wifi dongle that plugs into a spare USB port (preferably a USB 3.0 port) however I'd strongly recommend a PCIe plug-in card.

**Q: Will this support Ryzen 7 3700x out of the box?**
A: Yes it does finished my build with it yesterday

**Q: Can it support mvme ssd?**
A: It has support for two NVMe devices although only the first supports PCIe 4. The second supports PCIe 3. I use both slots with each having a capacity of 1tb. Either slot can support both PCIe 3 and 4 devices but you only get the fastest performance matching a PCIe 4 drive to the first slot. The X570 motherboard offers 2 slots and both are PCIe 4 capable.

**Q: Does this mobo fit a musetex phantom atx mid tower case?**
A: That depends on whether the Phantom ATX mid tower case can
accommodate a motherboard with the dimensions 12 in. x 9.6 in.
(30.5 cm x 24.4 cm).
