A single 5970 can draw ~300 watts when running Furmark.
Your config. says that you have a 1200 watt PCP&C, shouldn't have anything to worry about.

A single HD 5970 can consume almost 360w of power when stressed to the limit as the following OCCT test shows:




However, when playing a Crysis Warhead, power consumption is at a more manageable 241w for a single HD 5970. Of course if it is overclocked, then the HD 5970 would consume more power.

For simplicity sake, let's just say that two HD 5970 will consume 482w total. But actual consumption should be less since SLI and XFire technology is not 100% performance efficient. Meaning adding another card will not automatically double your performance.

Based on the above info, I will agree with ct615 that you should get a 750w+ PSU. I prefer Seasonic since they are basically the premier PSU manufacturer. But you can also choose from PC Power & Cooling, Corsair, Antec or XFX all of whom have their PSU built for them by Seasonic.

so a 1,000 watt silverstone DA 1000 would be enough to run 2-XFX 5970 4Gb??
