i just got a Biostar IDEQ 210v with AMD XP 2700. i plan on putting in 512 megs RAM and an ATI9600XT. is the 200 watt PSU enough for this? is it even possible to put in, say a geforce 6600GT with gig of RAM and run it on a 200 watt PSU? the wattage seems kind of low. im not too familiar with SFF and how they work.
