Spec'ing out my system I made a mistake. Like many people who haven't built systems in a while I simply added up the wattage of the devices and went shopping not really paying attention to things like 12v rail capacity. I did the math here: http://www.extreme.outervision.com/index.jsp and determined I needed 485w so I thought I was covered with a 500w PSU. I wanted quiet so I got a Nexus Breeze case (read: lots of extra fans and a controller purchased for cooling) with 500w Nexus PSU. Haven't assembled it yet but i'll be running this:
AMD 4400+
Asus A8N32-SLI
2x1GB OCZ Platinum Edition DDR500
2xWD 74gig 10k Raptors Sata II RAID 0
3xSamsung Spinpoint 250gig Sata II RAID 5
and drum roll please...
2x eVGA 7800GTX 256mb's in SLI
I already know I am going to experience shutdowns on load as I just saw a review by 3Dgameman explaining the concept of rails and the fact the Nexus 500w is underpowered in that department.
So.... rather than drop $500 on another supply or take the 15% hit for restocking the case+psu I was wondering if I could just buy a cheap power supply, stick it outside the case, and split the SLI load between the 2 PSU's. I can also power the three Spinpoints with the external PSU leaving the 2 WD HD, Mobo, CPU, 4 fans, floppy, DVD+RW, and *1* Video card for the Nexus. Does this sound like it could work???
