How much power is being drawn Tags: Homebuilt Gtx Power Phenom Systems Last response: March 19, 2009 3:26 AM in Systems Share MykC March 19, 2009 12:57:08 AM I'm trying to figure what is the minimum PSU that would run a Phenom II 940 and GTX 285. http://www.tomshardware.com/reviews/geforce-gtx-285,213... Does include the CPU draw or just the GPU.

Just because a cpu/gpu is rated at a specific wattage doesnt mean it will draw that much . Intels 65 watt chips typically draw half that under load see http://www.extreme.outervision.com/psucalculatorlite.js...

Even a quad core cpu and a GTX 295 system with a couple of hard drives will run fine on a quality 600 watt psu . The total draw is around 475 watts MykC March 19, 2009 3:26:59 AM Yeah, I'm suprised too, getting the amps though is another thing. Can't find your answer ? Ask !
