Am getting a new EVGA 1GB nvidia GTX 280 video card in a couple of days and have heard that they are quite power demanding will my current power supply (Thermaltake 700W) be enough? i have a core 2 duo Conroe E6600 2.4ghz, 4gig ddr2 800 ram, 2 sata 7200rpm drives, i also have 2 7200rpm IDE drives, 4 120mm fans, one 250mm fan and DVD/muli writer drive and there are at least 3 usb devices connected moreorless continuously. I searched on google and tried this power supply calculator called "eXtreme Power Supply Calculator v2.5" and it calculated my PC would need a 536W power supply minimum (at 100% load) but im not sure how accurate or how much i should trust it. thanks for any help.
Do you think i will have have a good amount of breathing room to add more devices? or am i coming close to my max?
It'll definately be close, getting something more powerful would be better but probably not necessary.
