Does anyone have any tips on how to keep your wrist straight while power chords? I can play power chord songs just fine (such as Nirvana's About a Girl and Blur's Song 2), but my wrist is bent little too much and I can feel the strain on my wrist.
Power Chord and Bent Wrist?

This is usually solved by maintaining good posture.
Make sure you have a strap set at a comfortable & efficient length, not too long or short. Tilt the guitar neck up and away from your torso enough that you can comfortably reach around the neck so your wrist is not bent and your fingers have all the access they need to the fretboard.
This tutorial covers good posture.
