You say you have a 750w PSU. If I'm honest, I don't know what it is. If it's a cheap one, then I would say "No"
I have a Corsair TX650w (Seasonic internals are current best) With the AMD FX9590 with Cool 'n' Quiet enabled. I am also running the EVGA GTX 780Ti ACX SC version. And this is rated for 250w by reference.
You must have the AMD 990FX chipset and latest BIOS (not beta)
Cooling must be average water cooled loop, the AIO (All In One) are OK, but custom is better.
I'm running the Corsair H100, and the H100i has been benched to be around 5c better.
I would set the alarm to 70c. The on-board temperature readings are never great. Mine gets to 60c tops and I understand this model is MUCH hotter than the FX8350 with the 125w thermal envelope.
Mine runs around 1.475v (could be maximum) and goes down as far as 0.89v
If you're concerned, set the multiplier to 20 and see what happens. This will max the processor to around 4GHz. Your cooling solution should keep this cool. If it doesn't you may need to part with some money for something a little better in cooling.
The All-in-One solutions have one drawback. The fluid WILL evaporate after 5 years, so will need to be replaced, or a way of fixing it so you can fill it up. There are mod sites which do this.
Custom loops need to be swapped with their fluids anyway.
If your PSU is made by:
Seasonic, then your PSU is fine.
If it's made by anything else such as Cooler Master, Thermaltake, I would look at replacing it as these are not as good as Seasonic based versions.
