Does it support Ryzen 5000 out of the box?

Most units ship with BIOS versions that boot Ryzen 5000, but older stock may need a BIOS update. ASUS supports USB BIOS Flashback so you can update without a CPU installed.

How many M.2 drives can I install?

Two M.2 slots, both PCIe 4.0 with heatsinks, plus eight SATA III ports. Populating both M.2 slots can share lanes with some SATA ports, so check the manual.

Is the chipset fan loud?

It is a small active fan and can become audible under heavy PCIe 4.0 load. In normal use most owners report it stays quiet, and the board has a fan control curve in BIOS.

Does it have built-in Wi-Fi and Bluetooth?

Yes. Wi-Fi 6 and Bluetooth 5.2 are built in, along with a 2.5G and a 1G Ethernet port.

What memory can it take?

Four DDR4 DIMM slots, up to 128 GB, with rated speeds up to 5100 MHz depending on the kit and CPU. High speeds depend on the memory controller of your Ryzen chip.

Is it worth it over the B550 version?

The X570-E adds PCIe 4.0 on more slots, more USB and SATA, and dual LAN. If you only need one GPU and a couple of drives, a B550 board covers most needs for less.
