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 single MSI GTX 770 Lightning 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.
The UD5H beats the older Z87 Sniper for power consumption, and out of the Z97 boards we've tested so far it comes out better than most.
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.
With Windows 8 having more market share, the impetus to improve POST times for Windows 7 systems might not be at the top of a manufacturers list. However the Z97X-UD5H puts in a good show under 11 seconds by default, and almost 9 seconds when stripped.

A: By that argument every chipset ever made should still support ISA.B: The Flex IO diagram on this very page specifically states "Total of 14 USB2 ports". I'm reading that as being a constant entirely independent of the number of USB 3.0 ports, but if you have any literature to contradict that, I'd be appreciative if you could link it.

Not sure I follow your logic. USB is probably the most used feature of a modern chipset (I suppose SATA probably gives it a run for its money though). Take a look at any USB 3.0 connector and you'll find 5 contacts which correspond to the SuperSpeed transmit and receive signaling pairs and ground, and then 4 more that carry the USB 2.0 signal and Vbus. This is how USB 3.0 achieves SuperSpeed while maintaining backwards compatibility, and the signals all need to come from somewhere.Intel hasn't posted datasheets for the 9 series chipsets yet, but there really isn't a heck of a lot of difference between them and the 8 series (in fact they're all currently listed in ARK under the "Products (Formerly Lynx Point)" heading). In the 8 series datasheet [ http://www.intel.com/content/dam/www/public/us/en/... ], however, Intel states: "xHCI USB controller provides support for up to 14 USB ports, of which six can be configured as SuperSpeed USB 3.0 ports." Intel also includes this additional note: "Some USB 3.0 motherboard down devices do not require support for USB 2.0 speed and it is possible to route only the SuperSpeed signals, as allowed by the USB 3.0 specification. In this special case, USB 2.0 and USB 3.0 signals will not need to be paired together, thereby allowing support for more than 14 USB connections."
Interestingly, although the PCH package only provides connections for 14 USB 2.0 signals, those signals can come from either the newer xHCI or the two legacy EHCI controllers which are still present on the chip.

Am I correctly understanding that as saying that by routing the signals separately you could create a USB3 only port that's not back compatible with USB 1/2?repoman27 - Thursday, May 15, 2014 - link
You're not allowed to do that according to the USB 3.0 Specification, but let's say you had an on board card reader that had a SuperSpeed USB interface, then you wouldn't necessarily be required to route a USB 2.0 signal to it as well and could use that signal for something else instead.repoman27 - Thursday, May 15, 2014 - link
If all the high speed signaling ports were Flex I/O ports, everyone who purchased a PC or motherboard based on that platform would be paying for an insanely large PCIe 2.0 switch with 18 downstream lanes/ports, an 18-port xHCI, and an 18-port SATA 6Gb/s controller plus 18 separate muxes to steer the desired signals to each port. I'm sure Intel would be happy to sell all that to the OEMs instead of just letting them use discrete controllers, but I seriously doubt it would end up lowering the BOM cost any. Flex I/O is just a way to keep the PCH package size down by steering features to a reduced number of balls. I'd rather be able to actually utilize all of the controllers I'm paying for.Not all of the chipsets offer 14 USB ports, and not all of the available USB ports are necessarily routed to external connectors or headers on the logic board. Some of them are used to connect devices on the motherboard itself or other embedded features. Also, since this many ports have been available since the 5 Series, Intel can't exactly regress the feature set while AMD is still offering 14 USB ports.

With the current "Flex IO" design, Intel implemented 20 high speed controllers (8 PCIe, 6 SATA, and 6 USB 3.0), but only provided pinouts for 18 of them, meaning that two controllers sit unused. To provide full I/O flexibility, Intel would have to implement 54 controllers (18 of each type), 36 of which would be unused. It sounds like a waste of silicon to me.gloinsir - Wednesday, May 14, 2014 - link
The Rear IO abuses a Renesas USB 3.0 hub to one USB 3.0 port into four, bringing the total number of USB 3.0 ports the motherboard can handle to eight.Oh the poor Renasus abuse.

I guess I don't really see the need for wifi built into my desktop motherboard. I'd rather have the dual NICs. But I guess I can see the advantage when it comes to building a computer for mom or grandma.Ian Cutress - Wednesday, May 14, 2014 - link
If you have a family, more often than not there is a central WiFi router in the house connecting to everyone. If the house/flat isn't all layed out in RJ-45, then if everyone has a computer it has to get the WiFi signal for connections. For example, I have my NAS connected via ethernet to the router, but the three systems in my office are all connected via WiFi, as well as the HTPC in the front room.plopke - Wednesday, May 14, 2014 - link
I am still confused about what PCI-Express and M.2 supposed to be in the end for like a regular consumer? One time i read M.2 stuff and pice express will use the same protocl then other times i read articles like this that they wont work together , etcAny change anyone has some googlde docs spreadsheet that show a table like
connecter type motherboard | protocol | protocol max speed | connecter type SSD | speed SSD | max theorictal performance | compatible
