Will the ASUS PRIME B550M-A WiFi II boot out of the box with an Intel Core i7-14700K?

Yes. The ASUS PRIME B550M-A WiFi II natively supports the Intel Core i7-14700K out of the box with factory firmware.

Can the VRM on ASUS PRIME B550M-A WiFi II handle Intel Core i7-14700K's peak power draw?

Under sustained multi-core heavy load (such as Blender, Cinebench, or unconstrained video rendering), the Intel Core i7-14700K draws up to 253W. The ASUS PRIME B550M-A WiFi II's VRM is rated for only 120W, which will cause MOSFET temperatures to exceed 105°C and induce thermal clock throttling of 25% to 40%.

What RAM memory type is required for Intel Core i7-14700K and ASUS PRIME B550M-A WiFi II?

The ASUS PRIME B550M-A WiFi II is built exclusively with DDR4 memory slots supporting up to 128GB. You must purchase a DDR4 RAM kit.
