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 - Idle

Power Consumption - Metro 2033

Power Consumption - OCCT

Power consumption on the Premium is markedly higher than any other Z77 motherboard we have tested.  This is attributed presumably to the extra controllers on board - the PLX 8747 and the Thunderbolt controller perhaps being the culprits if they are unable to power gate themselves down, as well as the mSATA SSD.  The ASUS P8Z77-V Premium also features an enhanced power phase system to maintain stability, which may be another factor.

Note: In our future PLX 8747 review, we find that these power results are a common sight on PLX 8747 motherboards.

    And so are the handful of people that would spend $450 on a motherboard. Reply

    I spent $300 on my Asus P6T (socket 1366) in December 08. I still use it today, only upgrading it with a USB 3.0 PCIe card and from a GTX285 to a GTX570, keeping it 'current'.

    The i7-950 and 12GB of triple-channel DDR3 keep it competitive with the upper 90% of computers made today, so I feel it was a completely worthy investment.

    Who else can honestly say they've had a computer for four years and have upgraded virtually nothing aside from the video card and still have performance competitive with the fastest computers sold today?

    Um, pretty much everyone that bought any kind of quad core?

    Mobo has always had almost zero effect on performance to begin with, CPUs have been faster than most people need them be in the last decade or so, GPU is the only thing that matters.

    This mobo is not expencive because it has any pluses in performance, but because of the extra frills and features it has... which are only worth it if you actually use them. I don't think I will need most of them currently, and can add them on to any computer if I decide to use them later on. So this mobo is not worth it for me.

    This is pretty silly, since A LOT rides on which CPU you're using and how overclocked it is. GPUs are DEFINITELY NOT the only thing that matters and this has been proven through hundreds of reviews and comparisons all over the net. Reply

    Never crazy. My last build was 4 years ago. 790i SLI Ultra. I've kept him alive with GPU upgrades from 9800Gx2 in 2008 to GTX 580 3gb x2 in 2011, Memory upgrades from 4gb to 8gb. This extends life yes, but you get to the point of no return and then have to build again. I am at that place now. Mobo is very important. It is the ground floor on which everything else must stand. I have had a bad Mobo in past and can tell you that it does not matter what GPU you have if your mobo is poo. I want a feature rich, stable, OC able board with plenty of room for expansion. Price is what you pay for this. Well worth it. Why is it that no one moans (much) at $600.00 GPu but they do at $450.00 MB???? It is what it is. Where I see bad pricing is SSDs $500-600 big ones for a 512gb.... Reply

    I don't understand the inclusion of the 32GB mSATA SSD with this motherboard, even more so at the $450 price point.

    As the article says, anyone paying that kind of cash can easily afford a bigger and faster SSD and the 32GB is barely enough for a Win 7 install. The only way I really see it being beneficial is if it came pre-configured to work as cache (using intel rapid storage tech or similar) but there would be no way for them to know which drive to speed up as there is no point in caching a fast SSD if one was installed as the OS drive.

    I really like that is has a mSATA port to allow a user to install a small form SSD, but including a 32GB drive these days is simply too small for a standalone drive and the configuration to get intel RST or similar working is not for the novice user (or so I've heard).

    I agree the mSATA seems a frivolous extra although I would give two reasons; 1. Not big enough, 128Gb mSATA would be nice though 2. only SATA 3G, the latest mSATA cards are SATA 6G but sadly not got a board to support this yet.

    If this is a true premium board mSATA should be SATA 6G then it would be truely quick

    the current mSATA spec only supports 3G as it is required to be linked to the 3G PCH port per Intel specification. Additionally see the feedback above regarding the 32GB mSATA module. Lastly a larger capacity mSATA would have considerably increased the cost which was already high especially considering all the logic some covered and some not covered in the review.

    Also would not in our analysis overall usage of mSATA is very low for users in the desktop space due to higher cost compared to standard 2.5inch SSDs. This is also why we integrated the solution to ensure a fully usable out of box solution for SSD caching.

    The 32GB SSD may be aimed at the Intel Smart Response SSD Caching Technology for a larger mechanical HDD.

    One may also use it for a Linux partition I guess?

    If I am to buy this, I may sell the mSATA. I wonder how much that will fetch.

    Yeah, I added a REVODRIVE 3 X2 (240GB SSD) to my Z77 build. It cost about as much as this motherboard but it doesn't need a puny 32GB cache to slow it down. My media is already on a NAS so 240GB is all I need for OS, software development and games.

    However next year I will definitely buy the premium LGA 2011 version, hopefully it comes with a 64GB SSD so I can add a backup drive under it.
