kahless Posted September 20, 2014 Share Posted September 20, 2014 So I picked up a 3rd 780Ti off ebay for very cheap since people are getting rid of them for the 980's. Here is my question: Is a Corsair AX1200 PSU enough for this: 3-Way 780Ti SLI +100mhz core, +200mhz memory 4930K 4.5ghz Rampage IV black edition 32 gigs 4X8Dimm ram stick Corsair H100i cooler 2x SSD 1x 7200 HD many miscellaneous fans in Coolermaster Haf-X case I've tried online PSU calculators and the numbers are all over the place. They have ranged from 1000 watts to 3000 watts. Link to comment Share on other sites More sharing options...
wytnyt Posted September 20, 2014 Share Posted September 20, 2014 yes the 1200i will amply handle a sli setup without any issues play on ! Link to comment Share on other sites More sharing options...
kahless Posted September 20, 2014 Author Share Posted September 20, 2014 Hi thanks for the info. It is actually an AX1200 and not the AX1200i if that makes any difference. Oh and this is TRIPLE sli if you missed that part... Link to comment Share on other sites More sharing options...

kahless Posted September 20, 2014 Author Share Posted September 20, 2014 Some people in the overclock.net forums say the PSU will run it but it will kill it before to long because it will be running it near its max capacity. Link to comment Share on other sites More sharing options...
sandstorm1 Posted September 20, 2014 Share Posted September 20, 2014 each card yanks about 250 watts each. 3 puts the total at 750. leaving 450 watts for all the rest. most fans are about 10 watts (some more some less). a larger PSU would give you more head room, and would future proof a bit. but, the 1200 will run it.

kahless Posted September 20, 2014 Author Share Posted September 20, 2014 I guess my biggest fear would be killing the psu prematurely by running it full throttle all the time when its already 3 years old. But I also hate to go out and by something like an ax1500 if I don't have to. Link to comment Share on other sites More sharing options...
sandstorm1 Posted September 22, 2014 Share Posted September 22, 2014 depending on the games you run i doubt you will max it out. Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted September 25, 2014 Corsair Employee Share Posted September 25, 2014 Some people in the overclock.net forums say the PSU will run it but it will kill it before to long because it will be running it near its max capacity. Those people are knuckle heads. AX1200 is rated at continuous output at 50°C ambient temps. It has all Japanese caps. The 7 year warranty is actually based on a life expectancy calculation considering 24/7, 100% load @ 50°C. Link to comment Share on other sites More sharing options...
