I think one bitburner XX with 20 chips is something around 100W, so yes this one is more then sufficient.
Edit: here is accurate power consumption:
Air:
431 - 54, 48, 1.30V, 87W, stable
450 - 56, 48, 1.30V, 90W, HW Errors
450 - 57, 52, 1.34V, 94W, slightly increased error rate compared to what i normally call "stable" but close enough
Water:
450 - 54, 32, 1.34V, 94W, slightly less hw errors then with air
