PSU for my build

OK, so I have:

IntelP45 motherboard
E8500 Wolfdale 3.16GHz
ATI Radeon HD 4870 1GB
7200rpm 320GB SATA HDD
2 x 1GB DDR2 800SDRAM
Probably soundcard + headphones, or headphones with integrated soundcard
Wiredkeyboard
This monitor
Wired mouse
DVD/CD combo drive
floppy drive

Also, I will probably crossfire 4870s in the near future
How much wattage will I need?

Also, money is a factor. The build without PSU is about $950, needs to be under $1100 total. Can I pull off the wattage necessary forthecrossfire for that price?

yes Corsairs are great, get the 750TX or the 850TX. I have the 850TX and crossfire 4890/4870 1 gigand its been flawless.
