Power Consumption

Power consumption was tested on the system as a whole with a wall meter connected to the Rosewill SilentNight 500W Platinum power supply, while using a single 7970 GPU.  This power supply is Platinum rated, and as I am in the UK on a 230-240 V supply, leads to ~90% efficiency > 100W, and 94%+ efficiency at 250W, which is suitable for both idle and GPU loading.  This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency.  These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.

For a mITX board, 500W is potentially a little overkill, even with the efficiency values listed.  As each of the motherboards tested are in the same environment, the qualitative differences between them are more  important than the quantitative values themselves.  Thus the board that is using the least power in our setup should also use the least power if a 120W pico PSU is used.

Power Consumption - One 7970 @ 500W Platinum

Out of the boards tested today, the ASUS uses the least power during loading, whereas the ASRock draws a little more than others while using a discrete GPU.

POST Time

Different motherboards have different POST sequences before an operating system is initialized.  A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized).  As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows starts loading. (We discount Windows loading as it is highly variable given Windows specific features.)  These results are subject to human error, so please allow +/- 1 second in these results.

POST (Power-On Self-Test) Time

All motherboards hit under the 12 second mark which is great to see.

    Interesting article, but I have to ask why would someone spend more for a Z77 chipset when using 'just' an i3? Surely a much cheaper H61 chipset could do the job admirably, and at much lower cost.

    Z77 makes sense if you're overclocking, which is excluded from this test...
  • IanCutress - Monday, December 31, 2012 - link

    H61 has no chipset USB 3.0, no chipset SATA 6 Gbps, and you are limited to PCIe 2.0. H61 is also technically limited to one single sided DIMM per channel, and no SATA RAID. There's also SRT to consider, that would be advantageous with the ASRock and the mSATA on the rear.

    It might make an interesting comparison to see what net advantage is gained with the added features of the Z77 chipset compared with the H61. If budgets are limited the ~100 dollar cost difference between the Z77 and H61 mainboards makes a big difference; that money saved could be put into something which makes more of a performance difference (SSD rather than HDD for example).

    Anandtech is one of the best tech sites around, you guys do a great job. I do sometimes see though an emphasis on more expensive products when in terms of real-world performance you could get almost the same thing at a much cheaper price. Might be worth mentioning somewhere.

    Not least because with yet another new socket coming with Haswell all these 1155 boards will be seen as out of date soon anyway.
  • IanCutress - Monday, December 31, 2012 - link

    Once we get into the swing with Haswell, we will hopefully covering the whole spectrum. Though it is worth noting that motherboard manufacturers, want to put their best foot forward, and would prefer their halo/channel boards get covered before their OEM / low end offerings. Hence this is why you rarely see many mainstream reviews that are not from forums dedicated to the market segment and users testing their own equipment. We are hoping to rectify the balance in due course. If there are any specific products you might want us to test or examine, drop me an email and I'll see what I can put in my schedule (as full as it is[!]) :)

    This is a major issue, not limited to motherboards: whenever I'm looking for something middle of the road or outright cheap, I can't find reviews.

    These Z77 MBs are a nice example: even though I'm recommending/building PCs regularly, most of them mini-ITX, I never came across a use case for Z77. Nobody apart from teens that still have something to prove overclocks anymore. People who want to do multi-GPU get a big case, and a big board. Are we supposed the extrapolate that the makers of good Z77 boards also make good H77 and H61 boards ?

    I understand you've got to make do with what you're given by the OEMs. And that reviews was very good, as usual. Pity it is irrelevant ?
  • Tech-Curious - Monday, December 31, 2012 - link

    That's an interesting observation. I have to say, I never noticed a significant lack of coverage for low-to-mid-range components (either in general or on Anandtech in particular), until this Fall, when I was in the market for a lower end motherboard.

    I guess I just always gravitated to higher end mobos before. Or maybe the coverage for such products was more comprehensive years ago. My memory's foggy, so it's hard to say.

    In any case, motherboards appear to be the exception. If anything, I think the internet has generally grown more bullish on low-to-mid-range CPUs and GPUs in recent years (probably, in part, as a result of the stagnating console situation, which results in stagnating system requirements for games).

    But all of that rambling aside, yeah. It'd be nice to see more diverse motherboard analysis. When I bought a b75 a couple of months ago, I literally couldn't find a review for that chipset. It wasn't a big deal; it's not like b75's features are any great mystery, after all -- but it is a little nettlesome to trip over sixty bajillion z77 reviews when there's nary peep about any other chipset.

    In other news, Ian's review is a good one -- and given that I've been a faithful user of Asus motherboards for the last 15 years, it's nice to see them take home the prize. :)
  • Etern205 - Saturday, January 5, 2013 - link

    My guess would be, why review a cheap board when majority of the readers here won't even bother buying it?
    And as for Asus boards, I've heard, they do something called based-line features. This means all boards from the bottom of the range to the top (Intel B75-Z77) will have the same base-line features, other features are just added like BT, WiFi, extra lan, etc.
  • Tech-Curious - Wednesday, January 9, 2013 - link

    Yes, I think the issue is that (at least with respect to Intel chipsets) low-end motherboards don't support overclocking. So they're both less interesting to review (fewer measurable differences in performance among different models), and they're less appealing to the presumed audience of sites like Anandtech.

    Still, the B75 is a perfectly good chipset. If you aren't heavily invested in overclocking, z77's advantages are likely wasted on you. Personally, I'm well beyond my overclocking days; I just don't have the time or the patience to go through the almost endless tuning process anymore. (Even if you find a stable OC at the outset, it can become unstable later, and/or a given application might expose instability that stress testing didn't, weeks or even months down the road).
  • jonjonjonj - Friday, January 4, 2013 - link

    just cause you don't overclock doesn't mean other people don't. why wouldn't you? because you want to get the fastest cpu that you can afford means you have something to prove? some people are just idiots.
  • Zap - Monday, December 31, 2012 - link

    But there isn't a $100 difference between H61 and Z77. There is a cheaper Gigabyte Z77 ITX board that's only around $60 more than the cheapest H61 ITX board, and it was even on sale recently for another $13 off making it less than $50 difference.

    Alternately one can go the H77 ITX route and get all the Z77 goodies except for overclocking, for around $30 less than the cheapest Z77 ITX. I think $30 more than H61 is reasonable for those extra features, plus guaranteed out-of-the-box BIOS support for Ivy Bridge.

    I do agree with your (mike_b) first post regarding the choice of CPU used. Ian Cutress, didn't you have a spare K CPU laying around? There are so many people building overclocked ITX rigs these days. I did in a Silverstone SG05 with low profile air cooler to hit 4.2GHz. Plenty of others use the Bitfenix Prodigy and liquid cooling to hit clocks normally reserved for ATX rigs. Another review site (Tweaktown) tested overclocking on Z77 ITX boards and the ASRock hit near 4.8GHz. THAT'S what I want to see.

    Of course this AnandTech roundup has some very useful information too, such as DPC latency tests and POST times. Keep up the good work there! But please, know your audience. Next time if the board is supposed to be overclockable, test that feature.

    Maybe there can be a companion article about overclocking and heatsink clearance? Would be a shame to not overclock this nice collection of Z77 ITX boards.
