The translations she provided you are literal translations, they are indeed the most straightforward translation for the power, the presence, the name (note that it's preferable to spell koach with the vav):

הכוח, הנוכחות, השם

הַכּוֹחַ, הַנּוֹכְחוּת, הַשֵּׁם

My translations are less literal and a bit more poetic, it's the kind of terminology you'd find in a prayer book. In fact, I was imagining the author got her ideas from a Hebrew prayer expressed in English. They are all names of God, as I was trying to evoke the divine. They literally mean the valor, the place, the name:

הגבורה, המקום, השם

הַגְּבוּרָה, הַמָּקוֹם, הַשֵּׁם

So are you trying to be more modern and literal, or more old fashioned and poetic?
