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 7970s (Idle)

Power Consumption - Two 7970s (Video)

Power Consumption - Two 7970s (Metro2033)

Power Consumption - Two 7970s (OCCT)

Due to the size of the board and the lack of phase loading in any serious manner, the Gigabyte Z77MX-D3H does rather well in power usage especially at idle.  During video, the board is somewhat thwarted with it's bigger brother needing less power.

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

The controllers on board the Z77MX-D3H do not add much for POST times, and overall the Gigabyte is rather slow compared to its competitors.  The ASRock Z77 Extreme4 for example is in a similar price bracket but takes around half the time to POST.

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!).

    I like gigabyte, nice review.

    However, those temperatures for the IB overclock remind me of prescott for some reason.

    Works great. Running it with an Ivy Bridge i5-3450 with 8GB RAM and an older 8800gt GPU. Reply

    Aren't those asrock computation results interesting. The board requires the least volts for your stress tests, yet it appears this is because the board isn't allowing the CPU to stretch its legs. Reply

    Looks like an even better board than the GB, and it looks like there might be more clearance for the front panel headers even with a 2nd GPU installed. Reply

    Can you confirm that F10 supports ecc ram?

    Thanks/liam

    are u guys planning to review: Gigabyte Z77X-UD5H?

    Would love to see how much better it's compared to mobo u've just reviewed and how it stands against ASUS and MSI offerings

    1 x 8-pin 12V connector (In spec table) or 1 x 4-pin 12V connector (In photo)
    and does it really matter / have any effect on power delivery for CPU or SLI/Xfire anyway?
