650w PSU enough?

[Gru]

I currently have a 650w seasonic prime ultra 80+ gold on my system.
I have overclock profiles ready to apply to both my cpu and gpu, but I'm not sure if my psu could safely handle the power requirements with both the profiles applied.

CPU: I7 9700k (@5ghz 1.35 vcore)
GPU: RTX 2080 Super gaming x trio (MSI)

Any input is appreciated thanks!

Your PSU is more then powerful enough. It will not pull much more then 350w-400w.

Cool, i knew that it would be enough for stock settings, but i was not too sure about the overclocking part, i was with the ideia that it would be too close to the limit.

a quality 600w psu is enough for any single cpu/gpu build

Make sure you have all the power inputs on your motherboard plugged into your power supply.

I think we're all assuming you don't have a bunch of hard drives and water pumps and radiators with big fans being powered off the same supply--and if that is true, then likely your 650W psu is enough!

If it is not, you can likely find out before long. You can sort of force your discovery of this by running something like the 3d mark firestrike and other benchmarks with the highest settings the demo lets you do and let it run for a while. I had my primary desktop crash repeatedly via such stress testing; I didn't have enough power. Better to find out that way than while actually gaming; it wasn't a problem at the time to get a new PSU (I was reusing an old one, and it could be the old one was not up to the task).

If you have a killowatt voltage meter (they go between like $25 to $40), that can plug into the wall and you plug your PSU cable into it, and the killowatt will give a real time display of what your pc (or anything--you plug into it --they are great tools in that regard) is drawing as far as amps, wattage, voltage, etc.

You can then get an idea of what your present, and anything in the future, power use looks like from a wall outlet perspective.

Those Corsair AXi PSUs can do it via software, but for those of us without one, the killowatt type of voltage monitor can provide a similar benefit while also being useful for anything else you can plug into it.
