Would be interested in some powered usb3 raiser cables for gpu's if you have any. Also with the DPS2000BB + breakout boards is their boards or support for 8 pin as well as the normal 6pin?
Don't have any riser cables unfortunately. I see no reason why you couldn't create yourself a set of 8 pin PCI-E cables, however these are already 36" 16AWG cables ready to go and all prepared. There would be little advantage to swapping them over.
