How I determine what key im in? Im using E5 D5 and C5 powerchords for my chorus in that order. Then I start over and go back to E5. It seems like no one really knows for sure, im getting mixed answers. so is there an actual stone cold way of knowing what key this is in? Thanks

You have had a series of answers that are all as right as they can be given you provide no direction as to the use of the chords, melody, etc. within a song context. You have 3 ambiguous chord forms, none of them complete chords but rather just the 1-5-1 of a chord. Right now they could be in the key of C major / A minor. But, as they are ambiguous, they could also be in the key of G major / E minor. Or the key of F major / D minor, but that would be less likely. So those are your choices. The actual key depends on your melody, but as Mike said in the first response you got, it's probably E minor, which is the natural minor in the key of G based on how your say you are using them. You identify the key based on the three keys which contain C natural, D natural and E natural in them.

That does actually exclude F major if we're talking chords, because it requires a Bb. That would be an E diminished power chord (which are fun and crunchy). Delicious tritones...

Yep - you're right there. That's what I get for theorizing at 2AM.... :D

Going with what Sriracha says, if you just use those three chords,and take the root notes and their 5th (which forms a power chord), you have C, D, E, G, A, and B. The only note missing from there is an F of some kind. Using those notes, you are left with two keys really, C major/A minor, or G major/ E minor. My indication is that the chorus you've written is in E minor, reason being that you're going back to that chord from the other two. It would be somewhat odd to have this song written in C but use this type of progression (not saying it's wrong at all to do so though). Are there any other parts of the song with different chords that you could provide? Or is it just the chorus?

I'd ask what scale sounds best soloing over the top of your progression - like has been said, I reckon Em
