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.

    Does the eSata port support Port Multiplier??? This should always be addressed when dealing with an eSata port. Reply

    the Asmedia controler used for the Esata ports does support Port Multipliers and FIS based switching which is required to work with most of the SI based backplanes. Reply

    I am very interested in both the Premium and Maximus V Extreme for my next build. I just can't decide which would be the better choice. The extreme overclocking features of the V are useless to me, but I do like that the mSATA is optional.

    Hopefully a review of the Maximus V Extreme is in the works and it will be compared to the Premium.

    The best review for the Premium I've read so far.
