I've had this one as well, and you're correct. It's two cables with two PCIe connections per cable.
Ok, I presume given that it'll be powering a miner 24/7 it would be advised to have dedicated cables for each PCIe connection...And my seach continues
It would likely work, but there are better PSUs out there for what you're doing. Such as the ones in my signature lol
Ah, yeah that does make a difference.
I'd go with the Cougar if those two are your only options, then.
