HeyYou Posted May 27, 2017 Share Posted May 27, 2017 Think I would go with at MINIMUM, a 750 watt P/S... I would be real tempted to go with a 1000 watt, just to have some additional overhead. Link to comment Share on other sites More sharing options...

Erik005 Posted May 28, 2017 Share Posted May 28, 2017 (edited) A 650W powersupply would be your best option, The cpu is 95W and the 1080 is about 200W. The entire PC will use 350W at full load at most. You could also get away with a 550W PSU. Nvidia recommends a 500W https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1080/ Edited May 28, 2017 by Erik005 Link to comment Share on other sites More sharing options...
L3s7ing Posted May 28, 2017 Share Posted May 28, 2017 I'm using two gtx 1080 with a max. power draw of around 250W each. Combined with the cpu and the rest of my system I get around 650W in full load.Still had my previous 1200W power supply and everything runs perfectly (no load psu fans or coil whine).The strix carsd are rated with 180W max power draw, but to have some oc capability I would also go with a minimum of 750W psu and to have a bit overhead you could take everything above. (850-1000W would be best, at least in my experience)Also, go with a quality one so it won't die after the first year. Link to comment Share on other sites More sharing options...

I would recommend a corsair RM750X Link to comment Share on other sites More sharing options...

Power draw on a PC is pretty much insignificant in a household. Granted, with that much overhead, you would never have to worry about being short on power....
