ASUS Maximus VII A2 error - maybe a different view.

I bought a "custom" system built by Tiger Direct from all in stock parts. ASUS Maximus VII MOBO,
32 Gig RAM,
250 Gig SSD (where the OS resides),
1 terabyte HD for data, 2 "bridged" liquid cooled, graphics cards,
850 W Power Supply,,

A very nice, very fast system. Although the system is under warranty Tiger Direct wants me to determine what piece of hardware is bad and work with the vendor although all parts were purchased from them and they assembled and warranted it. The local TG store, like all but 2 others in the US are closed.

My maybe different view - While I read the Forums below I see that my system's A2 problem which changes to a 64 when the SSD and HD are disconnected, seems to potentially be caused by either:
a bad MOBO
a bad hard drive
bad cables
bad power supply.

BUT it appears all Forums or nearly all forums have one thing in common, the ASUS Maximus VII MOBO. My question, I'm a novice at hardware but my IT and Analysis goes back to "Punch Cards" - is it normal to have a common factor such as the ASUS Maximus VII MOBO with all of these A2 errors?

I understand I qualified my query to finding ASUS Maximus VII MOBO and “A2” but there seems to be a lot of instances of this error. I also understand that ASUS produces high end IT products and are in demand, but the common thread of this error code and this common MOBO sticks out.

I do not have power supplies, SATA cables, spare hard drives, etc. to swap in and out to logically eliminate the cause of the A2 and 64 one piece of hardware at a time so my MOBO is on the way back to ASUS.

ASUS says they normally immediately send a replacement but they do not have any. Is the fact that ASUS is currently out of replacement ASUS Maximus VII MOBO also a telling statistic?

What CPU and cooler, what model # of the DRAM, what brand/model of PSU, what what cooled GPUs, should have extra SATA cables, the Hero comes with a few of them, you paid for them they should have shipped/given you everything you paid for (unless they used open box components that had missing parts)

Thank-you for replying.
Ultra Hybrid 850W ATX Power Supply
Intel I7-4790 CPU 4.00 GHZ, 8
LG 16X SATA Internal Blue Ray
Vengeance Pro Series 32GB (4X8GB) 2133MhZ C11
Samsung 250 GB SSD
Corsair Hydro Series STM H75 Liquid CPU Cooler
(2) XFX Radeon Double D R9-270X-2GB DD5
I TB HD

The SATA cable has unused connectors but the results are the same if the other connections are used - if any extra cables were in the original box they were not provided when build was delivered.
Thanks again,

I was referring to SATA data cables to try. Do you have a different PSU you could try, the Ultra appears to have the 12 Volt power spread across 4 rails (not a fan of those ;) ) Might try raising the VCCSA voltage about + 0.07 and the CPUVTT about + 0.05 and see if it helps

I do not have any extra desktop PC parts otherwise I would have started swapping them to help determine the cause. I could buy a replacement of each "part" mentioned in this ASUS Hero VII error code forum but should a person need to stockpile current parts? My question is not what to do to try and fix it, I'm familiar with the approach of swapping one part, connection, etc. at a time. My question was regarding is this an inordinate number of people with errors that only appear to have the MOBO in common? Yes, I know this is a forum for this but this just seems like a lot of problems, with near countless solutions/approaches offered, for a problem with one common factor - the MOBO.

Most of the 'problems' are easily solved, and it seldom turns out to be the mobo. I was just trying to see why this computer didn't come with all the parts, the mobo itself comes with more SATA cables than used, yet they keep them? and a rather suspect PSU for an SLI rig

Thanks. At this point, and after seeing it, two techs seemed set on the MOBO being the problem. Other potential solutions ventured all assume that a person has stocks of PSUs, hard drives, etc. In my experience MOBOs can be the problem. After a few years use the MOBO on my HP laptop went out. The replacement was also bad... Finally the next one worked. So two bad MOBOs in a row. Has now worked fine for 2 years. Not sure on the SATA cables. I did not sit and watch Tiger Direct build it to see if there were any extra parts and, if so, what they did with them. ASUS seemed convinced enough from the code and what had been tried that it was the MOBO as they authorized the return and they should have it this week.

Thanks Tradesman1. Contacted ASUS today. They received the MOBO, found a problem, have fixed it, and are now doing a 24 hour test. I hope this was the problem, and I hope the MOBO was the only problem. Hopefully in a few weeks I can update this site with something definitive.

Tradesman1, Motherboard was repaired and returned it has now been reinstalled and the computer and monitors all work fine... There were not any info. from ASUS repair other than they did not have a new one MOBO on hand and so they would diagnose and repair this one. All other hardware and wiring remained the same. Ahh, well, a leaning experience that ended up being fixed between semesters at college. Thanks again.
