Default How much power?

I plan on buying either Corsair or PC Power&Cooling PSU due to their 5yr warranties, reputations in this forum, and reviews. The question is what power output should I get. I currently have a 300w stock psu from prebuilt computer, and it has to be running > 90% load given the components that came with it. 4gb 800mhz ram, phenom x4 9150e, 500gb HD. I tried installing another HD but computer wouldn't turn on, I got nothing. My assumption was the PSU, and when I asked a tech about it, they were surprised that it ran with my current components.

I plan on buying a BIOSTAR TFORCE TA790GX 128M AM3/AM2+/AM2 AMD 790GX HDMI ATX AMD Motherboard
a phenom II x4 of some type, higher speed ram with intent of underclocking, maybe a low to mid-range graphics card, a 2nd HD, and Overclocking is in my future.

What do you think would be sufficient power given those future components?

I was considering CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7

Help is appreciated

Depends entirely on the graphics card but 650 is easily enough for whatever you get.
EDIT: With loads of headroom as well even for a second card.

Thats good to know being as I don't really plan on doing the whole crossfire thing, so i could probably drop it down to a 500-550w without worry correct?

Depending on the graphics card you get. If it's a strong 500w, you'd be fine.

Put it like this: the build in my sig works fine with a GTS250 and it uses a 425W enermax PSU.
