This is a good question, and a common problem resulting from the fact that SATA power cables were designed with much larger 3.5" and 5.25" drives in mind, where tight packing would not be an issue. The 2.5" drive format was designed for laptops using slide-in bays with built-in power connectors. Case designers have gotten creative finding tight spaces in which to tuck SSDs, without a lot of regard to how cabling would actually work.
I think your setup will be fine, but a work-around would be to use the last connector on the chain, which will require fewer contortions. If that one is attached to another device (I believe you have it attached to the fan controller in your Fractal case), you can use another cable just for the SSD.
