I'm going to post my entire system specs just to try to make this easier to figure out:
XFX Core Edition 650w PSU
XFX nForce 780i Motherboard
Intel QX6700 Kentsfield 2.66GHz (OCed at 3.2 GHz)
nVidia GTS 250 (x3) in three-way SLI
8 GB Kingston HyperX T1 DDR2 RAM 800 Mhz (OCed at 1066 Mhz)
Onboard Audio (RealTek ALC88S Chip)
Western Digital Velociraptor 160 GB HDD (Master)
Western Digital Gaviar Green 2TB HDD (Slave)
LG IDE DVD-RW drive
Logitech Z506 5.1 Speaker System
This is the reason why I'm confused on the power supply thing. Going by nVidia's page, and Hardware Compare, the GTS 250 is 150 watts at idle. So with htree of them, wouldn't it theoretically be 450 watts at idle? The GTX 570 is 220 at idle. Throw in one of the GTS 250s for a PhysX card, it would be 370 at idle. That still less power consumption than my three 250s put together at idle. So even under full load, shouldn't it draw less power than my current setup?
The GTX 560 448 is 210 watts idle, according to Hardware Compare. Just in case that 10 watts really makes a difference. GTX 560 448 vs GTX 570.
I'm going to assume this has a lot to do with the fact the 570 would need two power adapters plugged in, whereas the 250 only requires one?
Actually, now that I think about it some more, I suppose I could just go a single GTX 570/560 Ti 448, and just overclock it. That would help make up for the difference in the lack of a PhysX card.
