There's too many variables to take into account to give you a solid concrete answer like you seem to want. Everything inside the computer requires some amount of power from the PSU. What your PSU is actually able to provide is at this moment an unknown to me and every power supply will be just a bit different in what it will provide.
What good will it do you for me to say that sure your fine go ahead and get the card everything will work fine. I would rather say that there is a chance that when overclocking you may not get the power from your PSU to do that and that knowing that going forward will prepare you for the possibility of needing a larger power supply. Unless you don't have the possibility of saving $100 for a 750w PSU then...

The specs on the r9-280x call for a 750w psu but I have come across some that have a 650w psu and say that it works with it. Once you start overclocking you are needing more power so then it becomes harder for a 650w PSU to keep up.
You might want to price some 750w PSU's and see if you want to include a PSU change in the upgrade.

Thank you 2 for the quick answer @inzone So i would be able to run the GPU without overclocking?
@ZhyrikaN Are you sure? do you have proof? Can anyone else say something to this please? 😀

Add the CPU load to the Graphics card load and then add all the other components and you start to see that your 650w PSU might not be enough and that's why they recommend a 750w PSU.

You can get the r9-280x and it will run in your computer but once you start overclocking both the CPU and GPU you may need more power then your PSU can supply. So if you go into this upgrade knowing this then at the point your needing more power you'll know why and be prepared for it. It will all depend on your power supply and if it can keep up.

ah sorry he is right,i mistaken idle cpu with load.but still if you oc only the gpu it is okay with 650w. if you also oc cpu, it exceeds about 40-50w so you will be needing 750w.

So would i be able to OC the r9 280x while the i5-3570k is on turbo mode (3,8ghz or something like that)

the cpu will consume more power but still 650w can be enough. also turbo is different from oc. in turbo mode, 3 of your 4 cores are disabled and the other core gets speed boost. so it is for single-thread things and won't be an advantage in future gaming. and i still think 650 w is enough for both oc because 260 w for cpu is only exists at 5.0 ghz and i reaaly wonder how can you seed up that much, its not a wise move.so jt will consume about 200w oc,(disable turbo when oc, it us meaningless) and gpu with oc 360w, hdd about 15w and mobo 30w. the other parts are unimportantly low. so 650 w is enough.

There's nothing wrong with getting the card and using it in your computer it's the overclocking that is in question and the r9-280x does not need to be overclocked it will provide excellent FPS at stock. Those cards have heat issues anyway so overclocking too much will be a heat problem and not a power problem.
