That Corsair PSU will not be able to handle that setup. I'd say drop the expensive keyboard and upgrade to the TX-650. I've said it before and I will say it again - the people who are advocating cheaper power supplies are flat out WRONG. Having a power supply with more watts than you need doesn't hurt at all. However having a PSU with too few watts or the bare minimum will cause instability and system failure. I've seen this with my own eyes on more than one build so I am not exaggerating this.
