It is theorized this is a byproduct of the accretion of materials near a black hole residing in the center of the quasar.
Depends on how you look at "power" I suppose, but a quasar is similar to a pulsar in that it has high enough angular velocity to produce jets of EM and synchrotron radiation through it's poles but however, a quasar is orders of magnitude larger than a pulsar since a pulsar is just a single neutron star (Maybe 20-30km in diameter) while the quasar is a entire galactic nuclei.
It could be, but the definition quasi-star depends on the radiation output, NOT the shape.
Here are some,What kinds of energy sources are there?Where dose energy come from?What is energy?
Three main things come from a burning candle: light, heat, Thermal energy x

Quasar
A quasar is a galaxy that is radiating massive amount of radioactive energy. A quasar MAY have a black hole at it's center. A black hole is just dead star that collapsed in on itself.
A type of galaxy is probably the answer you are looking for. However, a quasar is actually an active galactic nucleus.
A Supermassive black hole .
No. A Quasar is a Black hole in center of some Galaxies. I think our Galaxy has one of them.
A big black hole.
Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.
The power source of a quasar is a supermassive black hole at the center of a galaxy. As material falls into the black hole, it forms an accretion disk that releases immense amounts of energy, generating the intense radiation emitted by quasars.
Astronomers have detected a quasar in a distant galaxy.
A quasar will have the brightest galactic centre.
