Gigabyte Z170-Gaming GT SATA Drive Mystery

First, I attempted to post this last night - thought I had - do not see it anywhere I have looked, so if this is a rerun it is not intentional.
Rebuilding an Intel DZ77RE-75K based system using the Gigabyte G170X-Gaming GT board. Processor selected Intel I7-6700K with GSkill DDDR4-3000 16Gb memory stick. System disk is a Samsung Pro 250 - with Windows 7 x64 installed from the Intel based system. When I shut down this system I had the OS drive - two other SSDs in a Raid 0 configuration and two HDDs used for storage, etc. There were two DVD rewriters installed and operational. I replaced a semi-modular Thermaltake 850 PSU with a Corsair RM750i full modular PSU.
After a couple of hiccups I got the build to boot to Windows 7 and thought I would be able to complete the next day. What I did not learn until the next morning when none of my installed programs were able to find the code - was that the Samsung was the only SSD or HDD the system saw. In addition neither of the DVDs were even powered - no lights, nada. Thinking I perhaps erred when I did not replace the Thermaltake drive power cables I replaced the one powering the the two DVDs. Happily one of the DVDs had power; in spite of being on the same cable the other DVD still had no power. Wondering if I might solve HDD missing by replaceing the power cables - I did that. NADA! No difference.
I was able to use the operational DVD drive to install the Gigabyte utilities that were provided. I disavowed all the Google suggestions and deferred the utilities offered. After that install I rebooted - nothing different. The only two SATA drives I saw were the DVD and the Samsung SSD.
This is not my first attempt at building or upgrading a machine. Probably have at least 10 completed and operational - this one has me stumped. I admit I know next to nothing of the UEFI option and what the implication(s) might be. Near as I can tell that should not make any difference on the drive visibility.
I believe that I am missing something trivial at this point. The machine boots into W7 - and appears all is well - just can not find the unseed drives. BTW, the drives are not visible in BIOS either.
Any ideas on what I am missing?

Sorry, i didn't quite understood the hdd problem. If the independent hdd are not showing either you have a faulty a motherboard or a classic case of Gigabyte troubleshooting.

I would suggest following this : http://www.tomshardware.co.uk/forum/275856-30-gigabyte-guide

Gigabyte boards could be tricky at times. Also you could check to see if the bios is up to date. Maybe that would solve your problems. But since the board (assuming) is new i would also start an rma procedure.

If the raid ssd was created in the previous system that should be the root of your problems. I believe you would have to 'rebuild' the raid for the system to identify it. Maybe you could use something like a disk manager to recover the data in the raid. Also i know that raid can be way too finicky with even the most minor change.

That might be a factor for the two Raid0 SSDs. Why then do the other two HDD that are not Raid configured not appear? Or for that matter - the missing DVD?
It is a trivial task for me to remove the power cables on the two SSDs and see what happens.
Thanks!
Later:
Not sure how this works at the moment. Let see what happens.
I removed the power cable for the two Raid configured SSDs - load optimize - restart - no difference..

Is it possible that the new out of the box 750i is faulty? Don't see how - some of the power is getting to the drives. Motherboard, CPU, water cpu cooling, fans, and LEDs all light as set up. My thinking is that if part works, all should be - How would I check each individual port on the PSU to verify it is performing correctly? Is that even possible/desirable??

Morning CBender,
I have a hard time accepting that a new board is errant - although it certainly would not be the first and won't be the last.
I do want to attempt to verify the PSU before I surrender on the board though. Thinking through it last night - it occurred to me that I could swap power cords on the PSU. Thinking that if I placed the cord from the working SSD into one of the apparently not working ports and it worked there - then I would be reasonably certain that the problem is not in the PSU. Also placing one of the nonworking cables into an identified as working port should eliminate the possibility of a failed PSU.
So intend to try that next - if it appears to be the PSU I can (shudder) replace the Corsair with the Thermaltake I removed - - -
Will update as I finish!
