Comparison to Other Reviews
Where applicable, the results in this review are directly compared to the following chipsets and boards which we have reviewed previously.
Power Consumption
Power consumption was tested on the system as a whole with a wall meter connected to the power supply, while in a dual GPU configuration. This method 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.
CPU Temperatures
With most users’ running boards on purely default BIOS settings, we are running at default settings for the CPU temperature tests. This is, in our outward view, an indication of how well (or how adventurous) the vendor has their BIOS configured on automatic settings. With a certain number of vendors not making CPU voltage, turbo voltage or LLC options configurable to the end user, which would directly affect power consumption and CPU temperatures at various usage levels, we find the test appropriate for the majority of cases. This does conflict somewhat with some vendors' methodology of providing a list of 'suggested' settings for reviewers to use. But unless those settings being implemented automatically for the end user, all these settings do for us it attempt to skew the results, and thus provide an unbalanced 'out of the box' result list to the readers who will rely on those default settings to make a judgment.
As with the ASUS P9X79 Pro I've reviewed, using something very CPU stressful, even on the Intel Liquid Cooler, makes the CPU temperatures shoot up even outside of a case.

I always thought Intel made their boards as a "reference" like Nvidia makes "Reference" cards; great if you want a basic but reliable board that doesn't have 9001 features you can mess with and set something on fire with at least.As for All Intel Branding... if only Intel made RAM...

Wow, the price of motherboards has really gone up. My top of the line Intel mobo from 2004 (D875PBZ) and my brother's top of the line Intel mobo from 2008 (DX48BT2) were only about $150; now they're double!BTW, I'm kind of surprised you didn't mention the audio here. But I guess nobody cares about onboard audio anymore since they're all basically the same Realtek codec?
Anyway, thanks for the review AnandTech, you always have the best reviews on the net!

Guys, I just had a look at Intel's Product Brief on this motherboard here: http://www.intel.com/content/dam/doc/product-brief...It says UV Reactive SATA Cables ARE included! Also, strangely, it lists under "Hardware Management Features" that it has "Processor Fan Speed Control" and "System Chassis Fan Speed Control!" AND it lists PCI Express 3.0 for all three ports! So if these specs are indeed correct, this review needs to be updated. Perhaps the reviewer got a crappy pre-release model/prototype?

Don't mean to be rude, but I expect a little more out of AT than:"However, to an enthusiast, it is strange to say that they sell well "
"While ASUS, Gigabyte, MSI and the test have teams of designers for graphical interfaces"
"I can much use for this in case errors arrive"
"A lot of motherboard manufacturers in X79 should be placing the first and second PCIe slots at least an extra PCIe width apart"
"There is a big gap in the I/O"
...and that was only on the first page.
Are other commenters just holding their tongues to be nice, or...?

-I love how small those chips are getting. Each year they appear more and more like if they were printed on the PCB.-They should put the first PCI slot nearest to the processor, because is the only one place which can be used to plug video cards without being blocked.
That would need extra space on the case for the last video card, if it takes 2 slots, but most cases have that extra space, so I think that blocking a potential PCI slot is worse that blocking a potential third card.
You do not want to put a triple video card system on a small case, because of airflow and cooling constrains. But if you spend all that money, is more probably that you also will invest on other cards, like decent sound.
-As ever, Intel motherboards are crappy and expensive.

While I agree, dual LAN without teaming seems a bit silly at this point in history and missing other bells and whistles (new BIOS type) at it's price point is a bit disappointing. However, unless I read this review cross-eyed (trust me, I have sleep problems, it's possible), this Intel board performs better than most of the 3rd party manufacturers who have much bigger groups working on developing their bread and butter products. Slot placement has seemingly always been a gripe by consumers from every board maker at various releases and certainly not an exclusive to an Intel board. I am not defending it, I am just saying, I have seen (maybe not here) board become recommended even though slot placement was a con many times.Maybe I am missing something here, but when a board is rock solid reliable, overclocks decently (if that is a feature a customer wants), and out-performs and/or is on par with 3rd party board performance at or near the same price point, isn't that a win?
I have never owned an Intel board in my life. If I read around the 'Net and see similiar performance comparisons, this could be my first.

While I agree with some points, 2 things i'd like to point out:- looking at the /relatively/ slim and non-bloated software controls - they are already a reason for some award ('common sense' one perhaps ?). Relatively to the bloat other companies can stuff ... one often avoids using them because they are essentially a few checkboxs / sliders weighting heavy tens or hundreds (CCC, *cough*) megabytes; leaving aside well guessed reasons
- subjectively, I've always considered a front panel with knobs as a proper method to control fans, not a software

I always use this motherboards. In last times I was hoping to try a Asus. But Intel MB are very stable. The warranties are excellent. Fail is a rarity in this motherboards. I agree is rare to see a review. In the weekend, I see the 2 new enthusiast boards & I correct my decision to try Asus. What I like of this brand is they always are in emergent markets as Mexico. For so many years. You can try his technology. Asus in the other side only bring the cheap models. Maybe a disttributor in a rare ocasion brings a premium model. The price is high but is worth it. My desktops rigs endure almost 2 or 3 years with me. Then I resell the rig and my clients fight for it. They keep the anothar 2-3 years. The value of a self made desktop is very high. First his performance is better than any standard desktop, so you only need to change it when is leap forward in technology. The resell value is high too. In self-made you can always change a part to improve performance. This is the reason why I don´t like iMacs, so closed mind devices. I you feel the power, you are a hard to eclipse person. I always tell my boss that bringing my self-made equipment becasue his Enterprise Hp desktops are a shame. The idea is if you follow company guidelines you are going to be very behind of reality & speed. Have a nice week!bellends - Saturday, January 4, 2014 - link
This mobo DOES support teaming. WTF dudeRodofhot - Tuesday, September 2, 2014 - link
They prob dont even know what teaming is they are just repeating some early reviews they read.There r two kinds of people ones who like Intel everything and they seem to remember the pros of an intel board and thoes who want a cheap alternative to an intel mb and they seem to recall any cons of an intel board even though those cons may be a farse. I've read this mb doesn't support PCI 3.0 and also that it does support it in this articles' comments. Notice the guy who states PCI 3.0 is supported includes a link. Like me he must be the type who remembers the pros I guess as a fan of intel I must go uncover the truth. My guess is maybe a relase bios left ver 3.0 unsupported as with the teaming.
