Strix Z270F Problem

[Riflestrife]

So I decided to upgrade my system from a Z68 board and a 2600k to a Strix Z270F with a 7700k and 32gig 2800mhz. Since I switched over to the new board I have been experiencing nothing but issues in which the board will refuse to boot if I have anything except my corsair K70 (2 cables) plugged into it and even then it sometimes posts, sometimes freezes, sometimes boots. It was running fine until I installed the corsair link drivers (I had both the power supply and H115i plugged into 2 o the USB 2 headers on the board). since then I have had these issues. The bios freezes if I have my Logitech mouse plugged into the board. I have an additional USB 3 Card plugged into the board which is helping because I can plug all these devices into that but thinking I'm going to have to just send the board back to amazon. does anyone have any different ideas? Additional details below:

 

Motherboard: ASUS ROG Strix Z270F

CPU: Intel 7700K

Graphics Card: Gigabyte GTX 1080 G1

RAM: 32 gb DDR4 2800 MHZ Corsair vengeance

Drives:

1x Corsair Neutron SSD 256GB Boot

1x Corsair Force 3 SSD 64 GB as cache

2x 3TB WD Black in RAID 0

2x 1TB WD Black in RAID 0

1x 500GB WD Blue

1x LG BluRay drive

 

Add in Cards:

1x USB 3 Add in

1x 4 Port Sata add in for BluRay and 500 GB drive

Power Supply:

Corsair AX 860i

 

I have tried the system both with the add in cards listed above plugged in and remove with no difference. Bios update made no difference either. Question is, is the board a lost cause and should I return it?

Well I emailed amazon customer service to figure out the process for an exchange. they already have a replacement shipping to me. Amazons customer service is awesome. Decision made for me I guess.
