Hi! Alright im in a bit of a pickle. I have just bought myself a Dimension E510 which comes with a 305w PSU and have received a 7800GTX as a gift. The box for the card says it requires a 400W PSU minimum (non SLI) 500W (SLI). So i was wondering if anyone else been through this problem? Will it run? If not anyone know a good PSU i can get to replace the standard dell PSU? or would u suggest i just get another card tht would work with my standard PSU (bye bye graphics ) ?
