Hello, I have a Precision 380 workstation with a factory 375watt power supply.  I'm looking for some recommendations on brand/model of power supplies that would work in my computer without case modifications.  I'm hoping for something between the 500 - 700watt range.  Add-ons that I currently have are: GeForce 9600GT, two DVD/CD burners, eSATA PCIe card w/ external 1TB drive attached, mirrored internal 80GB SATA hard drives & 4GB RAM. 

Thanks, Brian
