A quality 600-650 watt would do but 750watts are not much more expensive and would allow for a midrange GPU upgrade in the future. Seasonic, Corsair and Antec are the most recommended brands followed by XFX and OCZ.

For a system using two Radeon HD 6770 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 600 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 35 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

thinking about OCZ ZS Series 650W 80 Plus Bronze Power Supply, should be sufficient for small overclocking and crossfire?

The OCZ ZS Series 650W (OCZ-ZS650W), with its +12 Volt continuous current rating of 46 Amps and one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, will be more than sufficient to handle two Radeon HD 6770 graphics cards in 2-way CrossFireX mode and handle some overclocking.

For a system using a single Radeon HD 6770 graphics card AMD specifies a minimum of a 450 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 24 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

If your 430 Watt PSU has a combined +12 Volt continuous current rating of 24 Amps or greater then it should work.

Not that it will, but the worst would be the psu blows up, and takes all the components of your computer with it...
