PSU wattage for this particular build

Right now I'm considering a power supply for the following build

1TB Samsung Spinpoint F3 7200rpm
MSI nVidia GeForce GTX560 Ti Twin Frozr II 1GB
G Skill Sniper 8GB 1600mhz DDR3
ASRock Z68 Extreme3 Gen3 1155 Motherboard
i5 2500k processor

would a 600 watt be decent enough for overclocking the GPU and CPU?
Or would it be more around 700-750?

  1. 600 watts is plenty of power for overclocking that setup.
  2. It's not the wattage of the power supply that determines whether a power supply unit is capable of properly powering a system.

    For a modern system you need to look at the power supply unit's maximum combined +12 Volt continuous current rating and it should also have very good to excellent electrical noise, ripple and transient voltage suppression (i.e. high DC Output quality).

    For a system using a single GeForce GTX 560 Ti graphics card NVIDIA recommends a minimum of a 500 Watt or greater power supply with a +12 Volt continuous current rating of 30 Amps or greater and with at least two 6-pin PCI Express supplementary power connectors.

    Select from reputable brands like Antec, Corsair, Seasonic and XFX.
