a c 1106 ) Power supply

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.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

The Rosewill Performance Series 550W (RP550-2), with its +12 Volt continuous current rating of 35 Amps and with one 6-pin PCI Express supplementary power connectors, is electrically sufficient to power your system configuration with a single Radeon HD 6870. You will need to use a 4-pin Molex peripheral to 6-pin PCIe adapter cable for the graphics card's second 6-pin PCI Express supplementary power connector.

The Rosewill RP550-2 is not that good of a power supply so it's ability to deliver the power specified on its label while staying within the ATX12V specifications is suspect.

I have to agree completely with ko888 on this. I would simply not trust a Rosewill supply though. I wouldn't trust it to the extent I would buy a new one regardless. Use this list to help you:

You will find Rosewill down in tier 5, I wouldn't bother with anything other than tier 1,2, or 3.

Thank you for the information and the link, really appreciate it. I will change the PSU to some thing from Tier 1. Just to be on safe side and go with 700 Watt, leaving my self open for future upgrade in CF.
