I couldn't be arsed digging up the thread on here where Ben said it, so I'll c'n'p from globalpsybreaks. Do you doubt that Ben knows what he's talking about?
Psybreaks covers a very wide range and means different things to different people. Four main types:
1)Made by psytrance producers and basically sounds like psytrance with a breakbeat, typically in the 140s bpm. Mood Deluxe is the classic example, or Scorb "Ipso Fvcto"
2)Chunky electrobreaks/electrohouse which borrows production ideas and squizzy noises from psytrance: Far Too Loud, most Broken Robot releases, Kiwa, Hedflux, some Robosapiens.
3)Progressive psybreaks: Nuskoolbreaks/techfunk/progressive-breaks origins, epic evolving builds and breakdowns inducing hypnotic trance states. Effortless trippiness. This went on quietly for years before anyone thought to call it psybreaks. Chi Recordings is quite a goldmine for it, Sinister Recordings were the masters (now deceased), other Robosapiens, Plastic Shell, Amb, Skein, Omar Santana, also although I wouldn't call BETA or BSD psybreaks exactly, they often have the right sensibilities to fit in this category.
4)Glitchy electrobreaks/dark electro: from Espion and Marc Adamo at the more accessible end, via Butter Party and Kilowatts, to Lawgiverz, Jnr Hacksaw, Tipper, Skeetaz, SOTEG, Mr Rogers... Addictech is the place to shop for glitch and what I like to call "psywonk", tho it often descends into a game of Dodge The Dubstep....
