psu not cutting it?

[mikeo]

so i just rebuilt my system with the following new parts...
q6600
p5k-e wifi/ap
8gb ddr2-800

in addition to:
5 hd's (1 ide 4sata), and a nec burner
6800gt
fan controller w/ 4x fans and 4x ccfls
1 leadtek tvxp2000
1 ati hdtv wonder
and a floppy drive


I was powering it on an OCZ-520 12U 520 watt psu, and it runs ok on the default settings, but when i started to oc and prime each of the cores i watched as the 12v dropped from 11.8 to 11.6 to eventually 11.2... i stopped it right away and decided that i need a new psu.

What would you recommend if i plan on adding an 8800gtx or whatever the next big nvidia card is around next christmas? also plan on adding 1 or 2 more hds at some point... want to run the q6600 g0 at 3.8 (and with the current temps and my huge ass heatsink i think it should be able to handle it)...
thanks,
mike

would this psu handle it?

and do rosewill psu's still suck? (specifically this one)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182072

my current voltages for the default q6600 settings are
1.23 vcore (was set to auto in bios but seems to drop to 1.23 when i prime all 4 cores at once) its at 1.25 if i only prime 1 core.
3,28v 3.3+
5.09v +5
11.65v +12 (jumps up to 11.82 if idle)

I guess the vcore drop was from vdroop, maybe my powersuppily is ok after all... the 12v still drops but I changed the options in the bios and now the vcore only drops from 1.32 to 1.31 when all cores are primed. should i still be getting a new psu if the +12 is dropping to 11.6?

Your actual psu should be to power your proc and a gtx withou any trouble. 11v or 12v i dont think so its really affect something. And the the vcore don't set it to auto ( if you are overclocking) step one by one to the lowest stable one on prime. And you have a lots of Hard drive , i don't know what size are they, but if you could change 2 for 1 bigger, it will save you energy or just make a external storage station with an other power source. Because this psu could Sli gtx with your proc Oc easy. But with the hard drive you have. Well if you waiting like december for a video card nvidia say that their new series will consume less power than the 8800 gtx and perform bettter. This will be the end of the high wattage psu.
