I just want to make sure my PSU isn't going to brown-out on me. I'm running a Core 2 Duo 3.0GHZ (65W) as well as 4 sticks of DDR2 and a SATA hard drive. There's nothing special beyond that, just the basics, using onboard video and audio. I might add a wireless NIC, but I'm not so keen on that if I can find a way to run an ethernet cable cleanly. How much power should I expect to provide. I used one of the psu calculators online and it only said 160W. Does that seem reasonable? Thanks for all of your patience with my incessent simple questions!
