Holiday time is coming around and if the price for another 570gtx drops I might go SLI. I tried reading through the SLI/Crossfire faq but for some reason 570gtx isn't listed on nvidia's website for psu's.
CPU:i5 2500k @ 4.5ghz
MOBO:EVGA p67 sli micro
RAM:Corsair xms3 4x4GB DDR3 1333mhz (16GB)
GPU:MSI Twinfrozr III GTX570 PE/OC @ factory speeds
PSU:Corsair TX850 v2
Would my PSU be enough for another tfiii gtx570? I know some people on Guru3D were able to run nvidia gtx570's sli with a corsair tx750 but I don't know if they had OC'd processors and the nvidia card probably draws less power.
I also have 1 HDD and 1 optical drive
I have asked this question and all of my replies were yes it would so hope that helps. And i do believe the maxixmum power consumption of two 570's is like 500w leaving you 350w for the rest of your system. 95 watss for processor and about 100-200w for everyhting else. you should be fine. check this websitehttp://extreme.outervision.com/psucalculatorlite.jsp
on the website above i got about 670w for a system with exaclty your specs with SLI 570's
