Particle system for intro creation

Currently using other compositing VFX tools such as HitFilm Pro I'm searching for faster and easier to use particle system, with as goal to produce animated intro and effects such as this one

Being such particle systems (and also other options such as AE Particular plugin or C4D X-Particles) CPU based it's hard without high end hardware to produce something with 10 thousand or more particles and achieve such subtle effects.
Interested to know if will be possible to achieve this with Unity own GPU accelerated particle or some third party pack, and also export with alpha channel so to composite later the effect wth other assets.
