XFX 550W enough for i7-2700k+GTX 760 overclock?

[dmoment]

Hey, I joined here for some guidance. I put my build on outervision psu calc with a moderate overclock and it gave me load wattage of 500w and minium recommended psu wattage of 550w.

Here you can see the input I used and results here: https://outervision.com/b/XDWLgl
(Selected 16 hours per day Computer Utilization option because of the age of the PSU, but for example with 8 hours it would already lower the wattage recommendation by 15w.)

I would like to have atleast something around 4.5-4.7ghz OC on 2700k and for gtx 760 maybe something like this:
Stock | Overclocked
Core Clock 980MHz | 1130MHz
Boost Clock 1033MHz | 1183MHz
Max Boost Clock 1149MHz | 1306MHz
Memory Clock 6GHz | 6.5GHz
Max Voltage 1.2 | 1.212v
(from https://www.anandtech.com/show/7103/nvidia-geforce-gtx-760-review/17 )

This is my exact PSU: http://www.xfxforce.com/en-us/products/pro-series/pro-series-550w-psu-p1-550s-xxb9

It's been used on moderate gaming for 4 years now if that should matter.

My question to you is, do you think it should be enough for this overclock and what are the worst case scenario risks if any, and if it doesn't seem like a good idea, could I still safely go for a even more moderate overclock?

Appreciate all the help in advance

That psu will be fine. I would be surprised if that setup draws 500w under any realistic load you will likely be using the system for.
