Before you do/buy anything, you may want to check out this PSU calculator
to get a general idea of how much power you'll need for a specific system. It seems pretty accurate to me.
Thank you for teaching me that the differences in the amount of power all 3 of the cpu's I mentioned will draw is insignificant, and that the biggest draw on the power will most likely be the video card. I kinda thought so, but I wasn't quite sure.
So if that's true, then does that mean the video card draws more than like 125w? According to the PSU calculator (which I have used before as well), the e2180 oc'd to 3.0GHz at an estimated 1.4v will draw 122w. Is that normal?
Oh, and with the PSU calculator, I used the following settings to err on the high side (I'm including the obvious things too):
High End - Desktop
CPU Utilization (TDP): 85%
OC'd CPU at 3072MHz, 1.4v
2 Sticks of DDR2 RAM
two IDE 7200's (my 40's)
1 SATA (the new 250GB)
1 DVD burner
1 DVD reader
Sound Blaster - All Models
PCI NIC (just in case I decide to skip the onboard Gigabit)
3 External USB Devices (kb, mouse, flat-bed scanner)
1 Fan Controller
3 fans: 2 Regular, 1 LED
System Load: 90%
Capacitor Aging: 30%
So, if this thing is accurate, I can see that, even erring on the high side, I have plenty of headroom with the 550vx.
Cool! I like headroom!
