It requires a mass of 90 Suns in order to go hypernova. After 250 solar masses, it will not go hypernova and at 150-200solar masses, it might not go hypernova.
150-200 solar mass stars might instead do a pair instability supernova. This happens when gamma ray production takes to much energy away from the core. The gravity starts to overpower the outward push of fusion. It starts to collapse but it still has tons of fuel left. When it reaches a certain point, every ounce of fuel left fuses at once. The explosion is comparable to a hypernova but it is violent enough to destroy any remnant. No neutron star or black hole remains. This doesn't always happen, the balance can be maintained until the fuel runs out and goes hypernova but this happens most of the time.
After 250 solar masses, something weird happens. The process is often called photodisintegration. Awesome name but it does not create an explosion of any kind. When the core starts to collapse, the energy skyrockets. Except, the energy is enough to break apart heavier elements back to hydrogen (also known as fission). This in turn drains the supernova energy from the star so nothing can stop the collapse. The collapse continues until the entire star is crushed into a massive black hole. No explosion happens, the star just blinks out of the sky.
