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.

While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our test bed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers.  These boards are all under the same conditions, and thus the differences between them should be easy to spot.

Power Consumption - 2x 7970 at Long Idle

In our power consumption test, handling under 500W is standard for a Z87 motherboard, although the result was a little high compared to other boards.  OCCT and Long Idle numbers in general were relatively low.

Windows 7 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 7 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 Gryphon falls just short of our goal 12 seconds Windows 7 + dual GPU POST time.

    5thaccount, did it ever occur to you the reason you saw so many Asus returns is because they are the largest motherboard manufacturer in the world, and chances are if a noobie builder is buying a board, it's going to be...Asus?
  • Eagle007 - Tuesday, February 11, 2014 - link

    I am currently in litigation with ASus over a $350 motherboard they said was defective but have not returned to me. They have spent at least $5000 not to fight the suit and not return the board. They tortured me with emails, unanswered, and chat instructions for days before issuing a RMA. Do not buy a product from them with a five year warranty as it guarantees that you will be abused by them for 5 years rather than protected from failures.

    lol thats so dumb is ridicoulos. Asus makes excellent board, they have always done at least in the past 10 years since ive been building my own rig. Always use them Id rather get a lower specced Asus board than a higher specced msi or gigabyte. This is not just me speaking from experience, you can read forums upon forums of people expressing similar opinions. You're either trolling or got extremely unlucky. I just sold an x38 asus p5e board for over 100 bucks on ebay if that says anything.

    Odd. I've had nothing but Asus motherboards since the days of Ahtlon XP processors and none have ever missed a beat.

    I had a bad experience with an ASUS motherboard a few builds ago - which was actually something like 6 years now. The board was overvolting the RAM, so initially it would appear stable, and then degrade after a few months and start locking up with increasing frequency. I replaced the power supply, and the RAM twice before I figured out what was actually going on.

    Searching for information about the issue revealed that it was actually a relatively common problem, and that the voltages displayed in the BIOS couldn't be trusted. A workaround was to manually set the RAM voltage lower, to a number that appeared to be out-of-spec. I wasn't sure how much of an offset needed to be set though, and eventually the board destroyed that set of RAM sticks too. At that point I got rid of the board.

    Since then, I have been wary about purchasing another ASUS motherboard. It was probably just that model that was problematic, but having other options, it's still hard to choose to go back to a manufacturer that shipped boards with an issue as significant as that. Especially when they typically want a premium for their boards, too.

    hi i planned to buy PC..which brand motherboard is best..in service and relablity
  • FractinJex - Monday, February 3, 2014 - link

    Both obv. not to bright....I stated until I upgrade in 4-5 years did I state the board would only last that long....no

    Also this board as a 5 year warranty unlike 90% of other boards that have 3 year warranty. This is currently one of the best mATX boards available...

    No kidding, I think I have used 10-15 year old MOBOs. Rarely do they ever die.
  • drainplugofideas - Monday, February 3, 2014 - link

    Oh cool! I made nearly the same build. Cooler master n2000, i5-4670k, gtx 770, corsair MX 650.
  • Sabresiberian - Monday, February 3, 2014 - link

    I have one, too, quite happy with it. My only "complaint" is that the armor kit comes separately for a rather expensive price too, so that made what I paid pretty high all total. Still there are other premium small form factor mainboards in that price range (board+armor kit) - and with a 3 year warranty in stead of 5.

    The lower priced sound solution is a plus for me because I don't use mainboard sound, so the less it adds to the cost of the board the better for me. :)
