I noticed this too. They may have different effects, but the ship component with the greater effects really should have a different name. Much like Deflectors and Enhanced Deflectors.

Speaking of which, I don't know how many people have tried that component... It is really, really powerful. I was playing as Korath. I could easily fit 3 Psyonic missiles plus the basic amplifier on a medium ship with small defenses and a good engine. Giving me 21 attack in my space (which includes on recently spore shipped colonies). I put those suckers in fleets and I flying around with 70 attack fleets. Unstoppable. I didn't even bother getting the next tech up. Didn't need it to wipe the galaxy. Time to raise the difficulty.

I haven't tried the other races, but I hope they have something sufficiently powerful to counter that because ouch.

Ah, I didn't notice the effect difference. Cool! I LOVE these special components. They are very powerful, as you mention, and they add flavor. So far I've played as Terran, Acrean, and Drengin with the new enhancements, and it looks like each race has some sort of similiar item. Some provide powerful defense, others provide power attack so I think it'll all balance out in the end.
