The CPU temp is getting a bit high, which could be something like an improperly mounted cooler, or using one that just isn't efficient enough. I don't know how many drives you have in there, but if you have over 2, that 300W might be a concern.
What cooler are you using?
What else do ya have in the system?
Check in BIOS and check your manual to see how to adjust the Vcore, as you should be able to do it manually. Also, be aware of jumper settings, as Asus tends to use both.
