Not sure how much power I need

[SeegsElite]

Hi guys,

I'm building my first computer and I'm looking to buy a PSU, although I'm unsure how much power I'm going to need, my specs so far are,

Intel Core 2 Duo E6750 processor
I have a 8800gts OC 640mb, but I might have a 8800gtx when it comes time to build
GIGABYTE GA-965P-DS3 Mobo
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800
and i will have 2 500 gb hdd's in raid 0

Do you guys think a 520W will suffice??

Any feedback or suggestions would be great. I'm trying to stay around or under 100 bux for a PSU.

Depends on how much you want to future proof your machine, how many optical drives are you running. Also, how many case fans and size?

520 is good for what you got so far, but if you want to add hard drives in the future, you may wanna take it up a bit more. Any USB devices?

Really with the high quality parts you are putting in there, you should be spending more than 100 bucks for a PSU, you should buy a really high quality one for sure.
