I was just trying to get a recomendation on what size power supply I needed for my system.

AMD Phenom XII 940 3.0 GHz /w. factory heat sink
GIGABYTE GA-MA790GP-UD4H AM3/AM2+/AM2 AMD 790GX HDMI ATX
SAPPHIRE 100259-1GL Radeon HD 4870 1GB
2 Sticks of DDR2 1066 2GB RAM
Western Digital Caviar Black 1Tb HD
LG Blu-Ray/HD dvd player
2 case fans

I paid $40 for a 475 watt and I just got my computer put together and was playing Crysis when the power supply just gave up the ghost. I'm planning to order a 700 or 800 watt PSU; just want to get some feedback on it.

Thanks!
Jake

Double what you had.

The more capable it is, the longer it will last and the quieter it will be while it is running.
