The PCV-RS720G destop PC came with a proprietary 295W power Supply by Delta Electronics. Delta Electronics say they dont have a 400W power supply for my PCV-RS720G. Sony say the 295W Power Supply is the only one they have available for the PCV-RS720G. Some TechSpot Members have mentioned upgrading their PCV-RS720G to a 400W Power Supply. Anyone know where I can get a 400W power supply that fits in the Sony PCV-RS720G or one that can be made to fit?
