Each board is set to stock clocks, Speed Step and energy saving features are enabled, and the CPU fan is set to maximum. I use Windows default "Performance" power option preset for everything except idle power consumption where it gets set to "Balanced."

We're looking for oddities in the bench scores. Boring benchmarks are good benchmarks for motherboards. Dramatic score leads are due to motherboards cheating with hidden clock boosts while a board lagging behind is usually a configuration conflict.

With the Z97M-Plus numbers now in the scoring charts, the last of the ITX boards have dropped off the comparison table. It's just microATX Z97 from here on out.

Synthetic Benchmarks

Image 1 of 3

The Plus shows a small bump in 3DMark 11 physics, but everything else is pretty flat. I'll chalk this up to the odd way the Plus handles Turbo Boost.

Image 1 of 4

We see another anomaly in Sandra Multimedia where the Plus scores a little lower than the rest. Everything else is completely flat. Doing a little math, all the errant scores are almost exactly 5 percent lower. This again suggests the aforementioned Turbo Boost glitch since 4.0 GHz is 5 percent lower than the 4.2 GHz turbo clock the 4790K normally reaches. I think we have our culprit.

Gaming Benchmarks

The Plus falls in line with past gaming results. This is exactly the behavior we love to see in motherboards.

Application and Productivity Benchmarks

Image 1 of 4

Variances of one second are almost always due to rounding. The Plus shows excellent consistency here.

Power and Temperature

Image 1 of 2

Asus has a history of lower power consumption in their motherboards. Finer electrical control in the BIOS allows the CPU to run on less electricity and thus at a lower temperature. A smaller VRM hea tsink means higher temperatures on the power regulation circuitry.

Overall Performance And Efficiency

Image 1 of 2

We always like doing the same amount of work on less electricity. Asus notches a solid efficiency win over the ASRock competitors.

Overclocking Performance

Image 1 of 3

The Plus overclocks the BCLK better than the ASRock boards and can reach basically the same CPU overclocks. Unfortunately, RAM overclocking is hit-and-miss. Both ASRock competitors can push RAM to faster frequencies in both two- and four-module configurations and reach higher bandwidth at the 2666 and 2800 straps. The Plus does score a significant bandwidth victory at DDR3-2400, though, demonstrating much tighter auto timings at the lower frequency.

    Micro ATX has become that middle child that gets ignored most of the time.

    "I gave some meaningless style points to the OCF last time for its sharp colors. I give the same empty points to the Plus by not treating me like a squirrel and thinking stylish anodizing will sway my head."

    So apparently anodizing isn't stylish, and doesnt treat you like a squirrel, but when presented with "sharp colors", you sprint outside looking for acorns!

    We arent looking for a style review and you admit you are a sucker for one style, but then feel insulted when the next board isnt the style you prefer. That's hypocrisy.

    But thanks for the view from Tom's Styleware Guide!

    This board has M2 10Gb/S. That isnt on the specifications and should be. You did imply it, when you said a cable wasnt needed for M2, but it should be on the spec table.

    Why wasnt it tested with an M2 drive as the boot drive?

    Seriously, I kept hitting "refresh" thinking this was some archive from mid 2015. What's the relevance of running a z97 motherboard review now? That ship has sailed.....

    The first and second SATA ports are not forward-facing even though ports three through six are. I'm not sure why Asus would do this, especially since port one and two are the most likely to be used.

    Two SATA slots are forward facing because not all cases are made in such a way that sideways ports can be used conveniently (if at all).

    Other than if you're using a SATA M.2 SSD, it doesn't matter at all which SATA ports you use, so whether the 1 and 2 slots are forward facing or 3 and 4 or 5 and 6 makes no difference. 1 and 2 aren't any more necessary to be filled first than any other SATA slots.

    Minor typo re "shroter" at the end of the first page:

    "SATA cables are on the shroter side ..."


    Blazorthon's right about the SATA ports, one can boot from any of them.

    I rather like the form factor, one of the reason we're trying to devote some space to it.

    Try rereading it with your tongue in your cheek. Notice the points are meaningless and they both got the same amount? If a manufacturer wants to gussy up a board with fancy colors and RGB lighting, I will comment on that. If a mfr keeps things strictly business, I will comment on that as well. Neither impacts my final recommendation on the product.

    I didn't say I'm a sucker for anything except good function and value. It seems today there's a trend to make every computer component as fancy looking as possible. Personally I'd rather not pay extra money for fancy anodizing and RGB lighting. Just give me a product that works for as low a price as possible. I'm telling Asus that it doesn't have to dress up a board to get an award from me.

    It was on the spec table when I turned it in. Looks like it got lost somehow. I'll get that fixed. Thanks.

    Because the Z97 test bench components need to be kept consistent from one board to another so that the results are properly comparable. Right now we use a 2.5" 840 Pro since not all boards have an M.2 slot.

    This review was finished a while ago, but we've had so many things in the publication queue, it didn't come out till now. Regardless, just because Skylake is out doesn't mean Haswell is suddenly horrible. Skylake prices are so volatile and inflated right now, global availability still isn't assured, so a cheaper Haswell build is perfectly acceptable for many people right now.

    How is a forward-facing SATA port less convenient than a perpendicularly mounted one? What mATX case is so incredibly tight around the mboard leading edge that it can't accommodate edge-facing SATA ports? This board is narrower than the mATX spec allows so it actually has more room on the leading edge than a full size mATX board.

    I understand that port number doesn't matter when they're all SATA 6Gbps and that you can set your boot drive priority in the BIOS. However, for people that like to order their drives according to SATA port, it's annoying. Call me OCD if you want.

    With CPUs getting more power efficient, and with Haswell integrating some power control onto the chip itself, massive VRMs aren't as necessary now as they used to be. I understand it feeling like a cut corner given the board's competition. But at the same time, expecting to go for maximum overclock on a mainstream priced board is unrealistic.

    "I prefer windowless cases, and flamboyant colors don't mean anything behind a steel panel. A board only needs a good feature set at a good price to earn my respect."

    Very refreshing to read that. When I read tech reviews; some things are important to me like is the layout user friendly, performance/power used, thermals, and noise; things like PCBs with a checkered flag motif or extraneous LEDs are useless to me. It is annoying to find a product that fits my needs and know that it is more expensive than it should be because they decided to add cosmetic items like LEDs.
