Sr2002,
I successfully finished my project yesterday. I used the 3rd party cable I mentioned and managed to get the EVGA SN 650 to fit once I worked out a way to get it physically in - I had to dislodge the case rail that holds the case shut and then I could bend it out of the way enough to squeeze the PSU in place. I then used the cables that came with the PSU.
I have also now successfully installed a Gigabyte GTX 970 ITX mini which is fed by an 8-pin.
What did you do about the other power connector on the T1700 motherboard, with red, orange, yellow and black wires? That would be +12v, +5v, ground and something - similar to the selection on a SATA power connector, but it's a 2x4 pin black connector (and it's not the same as a PCI-6 or PCI-8 plug).
What the heck is that one anyway?Third party power supplies I've seen don't have one of those. Did you just leave that unpowered in your new config? Or did that require a second cable converter of a different type?
I'm speculating that might just be to provide aux power thru the motherboard to any peripherals that may happen to be wired up to be able to draw through that route (and none require it in a stock T1700, maybe?)
