Do I really need this much PSU???

[zerocool84]

I'm upgrading and using some old parts with my new stuff and thinking about a Corsair 650TX and wondering if I really need a PSU with that much power. I am not really too keen on getting a multiple rail system cus I don't want to miss-configure it and mess up my system. I'm going to be overclocking but not anything extreme.

e6300 (not sure about how high OC yet and will upgrade to a e8400 in a couple months)
AC Freezer 7
ASRock P43Twins1600 or GIGABYTE GA-EP43-DS3L
2GB DDR2 (will upgrade to 4GB when getting e8400)
SATA DVD-R/CD-R
2xATA 120GB
1xSATA 500GB
1x9800GTX (will upgrade to more powerful GPU's once a year)
Antec 900 4x120mmLED and 1x200MM fan

I want this PSU to last me a couple years which is why I'm thinking of getting something that costs this much since I've had my current PSU for 3 years and want it to last at least 1 mobo upgrade.

A good quality 400W PSU would be plenty. Earthwatts 430, Corsair 450VX, Seasonic S12II 430.
