Power supply concern on gpu overclock

[miscuitbiscuit]

Hello everyone,

I'm looking into overclocking my gtx 560ti to 1000mhz and around a 2290mhz memory clock.
I'm just a bit concerned about the power usage.
do you think my 500 watts will cut it?

my rig

PSU: Anatec 500watts earthwatts
Mobo: p5k
Cpu: q9550 clocked to 3.6ghz
Gpu: gtx560ti

According to what I entered you might be able to squeeze by. You weren't very specific so using what I assumed you'd have you'd be using 467W with the overclock.
