No, it won't fit. You have about 2cm clearance between the PSU and the barrier. The modular connections don't line up with the hole through it, and stick out too far before they can be flexed. To use that PSU, you'll have to remove the barrier and one of the hard drive cages. For modular or oversized PSUs, you're better off getting the PC-V1200.
I personally have a Seasonic 600W with my PC-V1000+
I can post photos soon if you want.
i have a modular PSU, NeoHE its modular-ness doesnt make it longer.
