Power Consumption

Power consumption was tested on the system as a whole with a wall meter connected to the OCZ 1250W power supply, while in a dual 7970 GPU configuration.  This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency > 50W, and 90%+ efficiency at 250W, which is suitable for both idle and multi-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.

Power Consumption - Two 7970 (Idle)

Power Consumption - Two 7970 (Video)

Power Consumption - Two 7970 (OCCT)

Power Consumption - Two 7970 (Metro2033)

A trend I have noticed over the course of Ivy Bridge testing is that the more power phases there are on a board, the more of the phases are ‘loaded’ during moderate CPU usage, such as playing video.  As these phases are at low loading individually, they are relatively inefficient than compared to high loading – this leads to a lot of power draw.  As the ASRock Fatal1ty Z77 Professional has a 16+8 phase power delivery, we see this explicitly with 150W system power draw at load – 48W more than the ASRock Z77 Extreme4.  There could also be other reasons for this difference, such as different signals to the GPUs regarding power required and how they power gate certain features.

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.  As requested in my initial Z77 review, we will also be showcasing normal and ‘stripped’ POST times, whereby controllers are turned off in an attempt to get the minimum POST time.

POST (Power-On Self-Test) Time

Overall, ASRock are posting some rather reasonable POST times, coming in at almost half the time of the slowest boards.  It seems that the controllers on board have little effect on the POST time itself, as the stripped time comes in almost exactly the same as the default time.

Overclocks

Here at AnandTech we want to provide quick and easy ways to determine if a board is good for you (with in-depth analysis of course).  So here is a quick round up of our overclocking results.  Overclocks are tested for stability with PovRay and OCCT - while these may not be the most strenuous of stability tests, it does offer a quick check for memory errors under high load (and also balances testing time with getting the next board on for review!).

    Hell yes to IDE port. It was very frustrating to find on my new motherboard no IDE but "great" SATA 6 was there. Marvell, 2 SATA 6 ports on single PCI-E 2.0 line. Who sane would use that instead of integrated Intel RST plain SATA 3? IDE controller would be way, way more useful.

    The same story with PCI slots on new boards: we get 0 PCI and 7 PCI-E. But hey, if you plug something in slot X then Y won't work, or if this 1x slot is used then that 4x would become 1x. How about providing fully supplied (or at least more supplied) PCI-E ports and filling space left with PCI?

    Yeah I like the IDE port, even if I'm going to rarely use it. They might as well shrink the header and give us a breakout cable to save space.

    I guess with USB 3.0, they could just give us an IDE to USB cable and solve the problem.

    This is why I kept buying Asrock boards, the slot layout and choice was excellent,
    eg. the P55 Deluxe is really good (I have several). Loved the 3-slot spacing for
    SLI/CF, has floppy/IDE (I use SAS RAID cards which usually need a floppy for
    BIOS/fw updates, and I was carrying over an IDE DVDRW), good price. Infact I
    didn't think Asrock's P67 boards were as good as the P55 Deluxe.

    The exception is my P67 board, an ASUS Maximus IV Extreme, because I got it for
    a very low price refurb, otherwise I would likely have bought a Z68 Extreme4.

    ...ATi logo on the board adjacent to the top PCI port.

    We actually see that on a lot of boards still. Perhaps it's time for a design update :)

    "There are six fan headers on the board – the CPU socket has two fan headers above the top heatsink, one 4-pin and one three-pin, and two above the first PCIe x1 slot (both are three pin). Other fan headers on board are at the bottom, where we find two three-pin chassis headers."

    One of the chassis headers is a 4-pin. I own this board, you can also see it in some of the pictures.

    They should remove the Gamer tag and brand this as what it is, a Home Server Motherboard. 10 SATA ports, IDE, Floppy, lots of fan headers, PIC slots. Not what most Gamers are looking for but it still might sell to the home server crowd.

    Gamers are hardcore competitive. There is no way I'm going to copy the setup of someone I want to beat. I'm going to do my research and build a better system to try and squeeze out those extra framerates to give me the edge.

    I build a lot of systems and I have never bought a "Wendel" component and I probably never will unless it clearly beats the competition, something I have never seen from a Wendel component.

    The fact that ASRock Fatal1ty Z77 Professional has built-in IDE and floppy connectors is one of the primary reasons why I will purchase this motherboard rather than the others in the same price range. Sure, I may never need to use these connectors again after the next system migration, but if/when I ever do in the future, I won't have to spend any additional money on expansion cards, nor will I need to allocate any PCI (Express) slot or USB port for them.

    On the other hand, I would have liked to see dual-link DVI, DisplayPort, and D-sub, or at least dual-link DVI and DisplayPort, instead of DisplayPort and HDMI, video output connectors on this motherboard. I have invested a lot of money in professional-grade monitors, and I am not going to swap them out simply because they are equipped with DVI connectors. Passive DisplayPort-to-DVI and HDMI-to-DVI adapters can only output single-link DVI signals.

    i have better aim that fatal1ty

    i have a frag of him somewhere, and every game i've played with him, my lg and rail accs are always better, 1.5x.

    I still want his stuff, he is p cool, and a great dueler.

    Wat u r describing is a lozer
