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 for the Z77X-UD5H was low at idle compared to the majority of the motherboards we have tested with, but draws the most power under OCCT and Metro 2033 (though not by much).

    Please note that even if you have purchased a '6Gbit/s' SSD, it will never run at that speed. If you look at our SATA and USB testing, none of the peak speeds we see in our benchmarking ever reach the peak advertised by the port due to the limitations of the hardware. They more often than not do not even reach the peaks of the hardware due to latency or real-world situations. Most rated speeds are for compressible continuous data with a high queue-depth - not ever a realistic scenario.

    Testing every 3rd party controller adds testing time. Going from 2-3 boards a month do maybe one and a bit. Especially if they're all connected differently on the board (which we don't always know without specific chipset diagrams for the specific product, which are not always available). After all, peak tests are limited in their understanding anyway - take the new USB boost technologies from ASUS and ASRock. ASUS' implementation affects mainly short size block transfers by several order of magnitudes (as found out in our testing), rather than peak by any significant amount.

    I am quite astounded by your insistence that if you have many ports that they must all run at their peak speed in conjunction with each other at the same time. It just doesn't work that way. Have a gander at the chipset diagrams in our first Z77 reviews to understand this. Bandwidth is delivered to what needs it at the right time - the usage model for hammering all the ports at once is almost non-existent.

    Ideally we'd love to test everything at the peak, but we do not have an unlimited amount of cash to go and buy equipment. We're independent freelance reviewers making do with what kit we can get together or are offered.

    I've become so spoiled by how incredibly seamlessly, fast, and consistent Thunderbolt works. Add to that the fact that I can probably get most of the specs in an external Thunderbolt enclosure/dock solution fairly soon...albeit for a tad more money.

    Wow, so Gigabyte finally took my complaints to heart and started releasing boards with something other than that ALC887 miserable excuse for an audio codec. Bravo good sirs, better late than never. Now get it done on more of your boards!

    I have this motherboard with an Ivy Bridge i5 3570K, currently at a stock speed, with a Plextor 128 GB SATA III SSD as the OS drive. Even with the post logo screen enabled, I get to desktop log-in in about 7 seconds. Excluding the "artificially" added time to type my password, full desktop is an average of 2.5 seconds from there. Not bad considering the programs I have that load versus Anantech testing.
    I have had my board since its early retail release and this has not changed much; even after replacing the original i5 2500K and Samsung SATA II 128 GB SSD for the above mentioned components.

    In addition to the boot time being misleading commentary and the response to the USB vs PS/2 keyboard, my present computer build with this Gigabyte board is one of the best/favorite rigs in my 14 years of building and tweaking computers.
    The other few are ASUS P8P67-PRO, Gigabyte MA790GP-UD4H (X2 with two cores unlocked to quad and STILL running stable), EPoX EP-9NPA+ Ultra, ASUS P5A with AMD K6-350 (severe electrical spike took it out after years of OCing - jumped the surge protector)!

    Is the reaction time DPC Latency error fixed on the Gigabyte Z77X-UD5H-WB-WiFi version or are they just the same motherboard with just a wifi difference?

    Ian Cutress wrote, "...a total of 10 USB 3.0 ports available (if you have enough USB 3.0 panels)."

    Does anyone know of any cases that will would allow you to use the 3 onboard USB 3.0 headers?

    Also, is it correct that the Gigabyte doesn't include drivers for these VIA controllers?

    Hay. I am wondering if the Gigabyte GA-Z77X-UD5H Motherboard will fit in the Dell E510 Case? Or which Case can i get? I would like to build a nice gaming pc that whill not break me. I dont have much money. My eMail is: etruett9@gmail.com..... :-))

    Hi, It's weird how in any of the reviews there was a word for the problems (bugs) this M/B has. I ordered it a week ago and even if I upgraded my BIOS to the latest version, it still suffers from problems.. I had for example to disable the Marvell sata controller and connect my drive to the intel chipset one for the system to shutdown properly... Other folks have had freezes etc. Google the model + problems and you'll see. I am thinking of changing it with an Intel m/b or something more stable..
