Five Z87 Motherboards For Your Mini-ITX Build, Reviewed

Z87 rules the PC enthusiast market by exposing the Haswell architecture's full feature set. We're particularly interested in mini-ITX-based platforms able to integrate Z87 in a compact form factor. Five boards contend for supremacy of compact computing.

Z87I-Deluxe Firmware

Asus' firmware has several overclocking modes, and the Z87I-Deluxe follows that theme. Selecting XMP overclocking mode before making other adjustments enables both XMP-memory and manual CPU overclocks simultaneously.

The Z87I-Deluxe properly selects the highest-functioning DDR3-2933 memory ratio for our Haswell-based processor, increasing BCLK to 102.3 MHz to enable its DDR3-3000 rating. We had to back it down to 100 MHz to find our CPU’s 4.6 GHz maximum frequency.

Heat is the reason our CPU tops out at 4.6 GHz, as core voltage levels greater than 1.25 V result in thermal throttling. We reached that limit at this motherboard's 1.245 V setting.

DRAM is even more aggressively over-volted; our voltmeter showed a 1.65 V output at the board’s 1.635 V setting.

Primary, secondary, and tertiary timings are adjustable. The top three settings switched from “Auto” to our memory’s XMP ratings when XMP mode was enabled.

Because the Haswell architecture's core voltage is internally regulated, we left load-line calibration settings at motherboard defaults.

    Here is another MSI ITX board

    Why would one pay extra for ASUS's power delivery if it didn't yield any additional OC/DRAM stability? In the end, ASRock features & cheaper price should be a better option here.

    Yes, they've sent one for another article. If the site did multiple items per manufacturer the article would take weeks to finish. That wouldn't be a problem if all Tom's Hardware did was motherboards :p

    ASRock's cheaper features also made it a competitor with the cheaper boards for the value award. Since it competed well for both awards, it had to get a different award.

    While some may not like the layout, the Gigabyte and MSI layout should work well in some cases like the SG05 from SilverStone. The top mounted power and sata ports help keep wires out of the air flow path.

    More room between the PCI-E and CPU LGA is nice on the Asus as are all the features.

    I am still running an older H55n usb3 24/7 and it has been quite stable and cool and low on power consumption. Shame that this new gigabyte board has higher power and temperature levels.

    Since most of them has built in Wi-Fi. Will it be better to include a Wi-Fi test column?

    We formerly had a controller reviewer, and I'd like to see someone take on this task again. A separate article on the controllers (with everything else identical) wouldn't tell you anything about the antennas included with different products, but antennas are cheaply replaceable.

    Is the Asus Z87 Pro the same as the Deluxe? Seems to be region specific but I can't find the difference. Help? I've just bought the Pro for myself as it is only slightly more than the MSI or Gigabyte options.

    I think that the Pro version comes with wifi-N instead of wifi-AC.

    Let's just roll some dice and toss out some awards, eh? Couldn't help but laugh through the conclusion.

    Overall it's good to see the roundup. Would have liked to see post times. With SSD storage, motherboard post times are now becoming the longer wait in a system boot up.

    Also interested in thoughts on reasons for Z87 mobos for a standard non-overclocking build. For a non-overclocked gaming ITX PC, say with an I3 or low-end I5, are there any compelling reasons to pay the Z87 premium over, say an H81, which can run $100 cheaper?

    Nice review and boards, conclusion is all good buy's depending on what features you want except the EVGA.
