Following on from the second of two Prime branded boards at launch, the Z370-P has a completely different emphasis altogether. The priority has been shifted towards a broader focus on pure value, and the Z370-P comes in at the lowest price of all the ASUS Z370 motherboards. In comparison to the Z370-A Prime board, the Z370-P is considerably stripped down from all the bells and whistles, with this board sitting firmly on its laurels of a base Z370 motherboard but with ASUS optimizations.

This entry-level offering features a full sized ATX frame with four DIMM slots supporting up to DDR4-3866 with a maximum capacity of 64GB in total across all four DIMMs. This board is the only across the entire ASUS launched range not to feature Intel’s I219-V Gigabit network controller, instead opting for a more value orientated Realtek controller. Along with the TUF Gaming pairing, the Z370-P makes use of the more cost-effective Realtek ALC887 audio codec, and in this case, there is no EMI shielding. Dotted around the PCB, there is a dedicated header for AIO CPU cooling in addition to three 4-pin PWM compatible fan headers.

For the storage, the board uses a pair of M.2 PCIe x4 slots, with one either side of the full-length PCIe slots. This comes along with four SATA ports sticking out of the board on the bottom right. For PCIe slots, the top slot is a full-length PCIe 3.0 x16 slot whereas the second full-length slot is pulling its lanes directly from the chipset (PCIe x4). This means that only two-way Crossfire is possible using the latency added chipset based PCIe slot. The Prime Z370-P also has four PCI x1 slots in total.

The rear IO has four USB 3.1 (5 Gbps) Type-A ports and two USB 2.0 ports, and the board also has additional headers for four USB 3.1 (5 Gbps) ports and four USB 2.0 ports. The video comes via HDMI and a DVI-D port, which leaves the 2.1 audio jacks, a combination PS/2 port, and a network port. 

While the Z370-P is not the most exciting board in the range, it covers the basics and users will be considering it as one of the cheapest entries into Coffee Lake and the Z370 chipset. While it has lower specifications than the Prime Z370-A, we expect it to be picked up by budget system builders using singular graphics configurations.

    It seems that the PCB which holds the silicon has changed between the 7th and the 8th gen. So they most likely needed to validate the CPU. The fact that they did not move the notch means they just did not want to (could not) introduce a new socket. Either because there were so many of the old ones, or there was no time, or they did not want to push the cost to MB manufacturers to revalidate the new sockets. Reply

    For a split second i thought finally some x370 goodness... but no.
    Shame, shame, shame!

    Amazingly well done. Excellent write-up. Reply

    Stupid question, I got the AsRock simple ITX board and it won't turbo my CPU at all (8400) like no turbo PERIOD. It never ever goes over 2763mhz?

    Anyone got any ideas on this? Am I just stupid and this is normal behaviour or what?

    FYI: GIGABYTE Z370N-WiFi is also HDMI 2.0 capable Reply

    Thanks for that info. HDMI 2.0 is a rarity and I've held off Coffee Lake as I research boards with it.
    So far:
    - GIGABYTE Z370N-WiFi
    - Asrock Fatal1ty Z370 Gaming-ITX/ac (not explicitly stated but the last z270 version had it and it's implied by "- Supports HDMI with max. resolution up to 4K x 2K (4096x2160) @ 60Hz")
    - EVGA Z370 Classified K

    so I think the article's table should be updated to reflect this.

    with the EVGA Z370 Classified K being the only full size or 4 dimm slot mobo with HDMI 2.0

    HDMI 2.0 is important not only for the 60hz support but one of the requirements for Playready 3.0 DRM used by 4k media e.g. Netflix, Amazon, is that ALL displays ports on the system needs to support hdmi 2.0 with hdcp 2.2. So if you want to enable the CPU's GPU with a discrete card or use an AMD card, then onboard HDMI 2.0 is a must to playback 4k content.

    I agree, that HDMI 2.0 is important.

    But everyone must take care: The Asrock Z370M ITX/ac (non Gaming) supports only HDMI 1.4. Asrocks specification state “Supports HDMI with max. resolution up to 4K x 2K (4096x2160) @ 30Hz“. The Gaming variant supports HDMI 2.0.

    @Ian: I think it's worth to be mentioned in the description of th boards as well as in the selection table at the last page.

    If nothing else, Asus makes some damn good looking boards. Reply

    My big question still on the z370 is whats the 390 going to bring? Will the 370 not support a octocore chip? Reply
