For a system using a single AMD reference design Radeon HD 7870 Boost Edition graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 33 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The OCZ CoreXStream 500W (OCZ-CXS500W) power supply unit, with its maximum combined +12 Volt continuous current rating of 37 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single Radeon HD 7870 Boost Edition graphics card.

It's only a budget/entry level PSU so you shouldn't subject it to overstress by overclocking the CPU and/or GPU for any length of time.

ok and thank you i dont plan on oc'ing till i have enough money to buy a high end corsair psu anyway but i did also wonder whether the fact that is was dual rail would make the setup any more difficult because i read somewhere that you have to divide power between the rails manually

You don't have any control over how the power is divided between the two +12V rails.

The CPU receives all of its power from one of the +12V rails and the rest of the system gets its +12V power from the other +12V rail. That's just how the connectors are wired for that OCZ-CXS500W.
