Question 1

Is the Prime Z390-P better than a B365 motherboard?

Accepted Answer

The Prime Z390-P is the better choice when you plan to use an unlocked Intel K-series processor, enable memory overclocking, or need the expansion flexibility of a full-size ATX board. Intel lists Z390 as supporting IA, BCLK, and memory overclocking, while B365 does not support the same level of CPU overclocking. A B365 board is more suitable when you are using a locked processor and want a basic, cost-focused system.

Question 2

ASUS Prime Z370-P vs Z390-P: is upgrading worth it?

Accepted Answer

Choose the Prime Z390-P for a new 8th- or 9th-generation Intel build when the price difference is small, because Z390 adds native chipset support for USB 3.1 Gen 2 and is designed for the 9th-generation Coffee Lake Refresh platform. The performance difference between two otherwise similar boards is usually limited by the CPU and GPU rather than the chipset, so an upgrade is less compelling if you already own a working Z370-P and are not changing processors or connectivity requirements.

Question 3

Is the ASUS Prime Z390-P a good choice for a multi-GPU mining or compute build?

Accepted Answer

The Prime Z390-P is a practical fit for a legacy multi-card build because it provides two PCIe x16-length slots plus four PCIe x1 slots, for six expansion slots in total, and supports Above 4G Decoding according to the listed product configuration. It is most suitable when you already have compatible 8th- or 9th-generation Intel hardware; for a new compute system, confirm operating-system, driver, power, and riser compatibility before purchase because the board uses PCIe 3.0 and an older LGA1151 platform.

Question 4

Should I buy the Z390-P or a newer Z690/B660 motherboard?

Accepted Answer

Choose the Prime Z390-P only when you are reusing an LGA1151 8th- or 9th-generation Intel CPU and DDR4 memory. Choose a newer Z690- or B660-class platform for a new build when you want support for newer Intel processors, newer PCIe standards, and a longer upgrade path. The Z390-P is a platform-match purchase rather than a forward-looking upgrade because its CPU socket and PCIe connectivity are from the 2018-era Intel desktop platform.

Question 5

ASUS Prime Z390-P vs Prime Z390-A: which one should I buy?

Accepted Answer

Choose the Prime Z390-P when you need a lower-cost ATX Z390 board for one graphics card, standard storage, and a 9th- or 8th-generation Intel CPU. Choose the Prime Z390-A when you need stronger onboard audio, more SATA connectivity, multi-GPU support, additional rear I/O, or a more feature-rich platform for tuning. Both use the LGA1151 socket and Intel Z390 chipset, so CPU compatibility and core platform performance are similar.

Question 6

Does this product include the CPU, memory, graphics cards, or storage?

Accepted Answer

No. This is a motherboard-only product. The CPU, DDR4 memory, graphics cards, storage drives, power supply, case, and operating system must be purchased or supplied separately.

Question 7

Are all six PCIe slots full-speed x16 slots?

Accepted Answer

No. The board has six physical PCIe slots, but they use different lane configurations: one PCIe x16 slot, one PCIe x16-length slot operating at up to x4, and four PCIe x1 slots. It is designed for expansion and multi-device setups, not six full-bandwidth x16 graphics cards.

Question 8

Which processors are compatible with this motherboard?

Accepted Answer

It supports Intel LGA 1151 processors from the 8th and 9th generation Core families, along with compatible Pentium and Celeron processors. The processor is not included, and some CPUs may require a compatible BIOS version.

Question 9

Who is this motherboard best suited for?

Accepted Answer

It is best suited for DIY builders who already have, or can obtain, a compatible 8th- or 9th-generation Intel processor and need an ATX motherboard with multiple PCIe slots, SATA connectivity, USB 3.1 Gen2, and multi-GPU configuration support. It is less suitable for buyers seeking a current-generation platform or a simple ready-to-use computer.

Question 10

Is this motherboard suitable for a multi-GPU cryptocurrency mining rig?

Accepted Answer

It is suitable for builders who need multiple PCIe expansion slots because it provides six PCIe slots and Above 4G Decoding support. However, six installed GPUs are not guaranteed to work automatically; results depend on BIOS settings, risers, power delivery, GPU drivers, operating system configuration, and lane or resource limitations.
