[willdav]

hi,i own a coolermaster hafx full tower utilizing 8 fans, amd 955 processor and msi 6870. i had previously owned an Ultra 750W psu before it just suddenly died.
i need help in choosing a good psu that will stand through time and deliver the power performance that any pc gamer is looking for

For a system using a single Radeon HD 6870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

A combined +12 Volt continuous current rating of 30 Amps or greater should be enough to handle a system using factory or manually overclocked Radeon HD 6870 running Furmark GPU stress testing.
