Thanks for chipping in... I do have the SAGA II already, it has only a single 6pin pci-e. My plan was to have an nVidia card initially, and then later on if I can afford to upgrade this GTS 450 would be a dedicated Physx. Of course I'd get a more powerful psu by then also.if you have the hardware already then try it.
if the psu has a dedicated pci-e 6-pin plug then I would try it.
but if having to buy hardware then I wouldn't buy it, no.
I'd spend the extra dollar or two and get a worthy power supply.
nowadays look for a psu that has 2 6-pin pci-e plugs for future-proofing,
just in case you upgrade to the GTX 460 or greater and they require 2 6-pin plugs.
I do not recommend adding a bunch of adapters to a power supply in order to power a gfx card.
IMO..
worse case scenario(s):
1.) unit will not boot
2.) during load times (gaming or heavy video) the screen will go blank and or display will go out.
3.) random BSOD's
4.) if the psu blows then so what, it won't fry the system with the failsafes the psu has installed.
I have ran a GTS 250 and GTS 450 on a weak 430-watt Thermaltake that had the 1 6-pin plug.
what is the nVidia card you want or have initially to run first, I had a 8600GTXXX and then a GT 240.
I also have a phys-x set-up with a GTS 240 (OEM) and a GTX 560Ti, it runs on a 700-watt Rosewill SLI psu.
no, the psu comes with 1 6-pin plug, no adapters needed.
