Source of powers in Mass effect series

This question out of curiosity, we have been seeing powers such as Overload, warp, lift, adrenaline rush and so on. I knew that these powers depend upon our character class but what exactly give the characters these powers.

Is it the advanced cybernetics or the whole magic lies in the Omni tool. Where few seems to generate from characters hand and some from Omni tool. In fact powers such as concussive shot comes right off the weapon.

So where exactly does the character get these powers?
