Is this PSU good enough?

Hello everybody. I am new here.. I am going to be ordering my new pc parts soon and I need a bit of help deciding on a power supply

I have:
Mobo: ASUS AM3+ SABERTOOTH 990FX S/L
CPU: AMD FX-8120
GPU: 2x Sapphire Radeon HD7770
Ram: 6gb 1600mhz Corsair
Case: Zalman z11 Plus
Storage: 500gb 7200rpm HDD (might add an ssd later)

At the moment I am planning on getting the Corsair CMPSU-600CXV2UK Builder Series 600W Power Supply..

Is this power supply good enough? Or do i need to go with something like a 750W

Now I know going with a 750 would be "better" but im not really interested in better.. as long as it will run ok i will be happy

Thanks!

Plenty good. A 750 wouldn't be better really, just more overkill
At 80 watts per 7770 you have plenty of OCing room, too.

Ok great thank you! that was quick!
I am planning on getting a h60 or a noctua nh-d14 at some point so that i can overclock my cpu in the future

Power supplies are such a mystery to me.. lol

Glad I could help

You can overclock those bits to the moon and back with that unit.
Id get the Noctua, between those two.

Thermaltake has this nifty little calculator to estimate how much power you'll need based on what components you're planning on having in your PC:
