ROGX Posted April 10, 2014 Share Posted April 10, 2014 Which one should i go with? i currently using 1 780 , but i plan on sli'ing in the future, + Watercooling, and heavy overclocking, with 860Watts be enough? if not should i go with the AX1200i? Thanks. Link to comment Share on other sites More sharing options...

Corsair Employee jonnyguru Posted April 10, 2014 Corsair Employee Share Posted April 10, 2014 He doesn't need a 1200W for just two GPUs. I'd recommend the AX760i. Link to comment Share on other sites More sharing options...
Pixelmancer Posted April 10, 2014 Share Posted April 10, 2014 He doesn't need a 1200W for just two GPUs. I'd recommend the AX760i. 760w would be barely good enough already and leaves no room for capacitor ageing or upgrades. Plus heavy overclocking is going to eat power too. 860w minimum in my opinion. I'd go with 1200w just to be sure though. Dude has a grand of GPU in there and spending another ~$500 on a custom loop. He's not trying to cut corners.

Corsair Employee jonnyguru Posted April 10, 2014 Corsair Employee Share Posted April 10, 2014 TDP for GTX780 is 250W. And 2 cards doesn't mean 2 times the power (unless you're mining, which I'm sure he isn't or he'd use AMD cards). If you want to allow for overhead, especially with the overclocking, than by all means use an 860i. But 1200i is just way out. Using a digitally controlled PSU with all 105°C Japanese capacitors is hardly "cutting corners". Link to comment Share on other sites More sharing options...
Pixelmancer Posted April 10, 2014 Share Posted April 10, 2014 I just put a fairly normal high end gaming PC with his GPUs and a water pump into a PSU calculator. I didn't know his other parts so I just used what's in the rig I'm building. I added an extra 30% for capacitor aging, which is what the calculator recommends for systems run 24/7 for a year. Minimum wattage was 831 and the recommended wattage was 881. That's with no overclock by the way. Why is the PSU company trying to convince him to get a cheaper PSU anyway?

skrybe Posted April 11, 2014 Share Posted April 11, 2014 I bought an ax760i for my setup - 4770k, 16gb ram @2400, AMD 7970, 2 SSDs, 2 HDDs, Bluray on a Rampage VI Formula. I've done some mild overclocking on it and the most power draw I saw was about 280w. That was in artifical stress testing, it normally sits about 240w during gaming. And sitting in windows typing this I'm seeing 113w in and 98w out. That's the beauty of the "i" series you can see just how much power is actually needed. And even swapping the 7970 for a pair of 780s or 290x is still within the limits of what the 760i can do, so the 860i should be plenty. Link to comment Share on other sites More sharing options...

Using a digitally controlled PSU with all 105°C Japanese capacitors is hardly "cutting corners". Thanks, i did some research, and saw that 2 780 Ti's Pulled a maximum of 508w under heavy load. Im moving towards the 860i, but im a little conserned about not having enough power. How much power would my other parts pull +508w? My specs are- 4770k @4.4Ghz 1x 780 Overclocked Going to sli in the future with 1 extra 780. 16gb Dominator Platinum Asus Maximus vi formula 1x 2tb WD black 1x intel 520 SSD 4x SP120's 5x AF140's And a full custom loop. So the question remains with all that, and still have plently of (For upgrades) wattage, a 860i or 1200i? Link to comment Share on other sites More sharing options...
ROGX Posted April 11, 2014 Author Share Posted April 11, 2014 I'd go with the 1200w. i saw that 2 Gtx 780's pulled a maximum of 508W, how much would the rest of my system pull? including a full loop? and heavy overclocking? im kinda leaning towards the 860i, but if i won't have any overhead, then i'll go ahead and get the 1200i. Thanks. Link to comment Share on other sites More sharing options...

Yup, i used the same Calculator, with all my specs (Pump,Overclock, 2x 780's, and 30% Capacitor aging), and it came out to a total of 990w on reccomended PSU wattage. If only they made a AX1000i.

That calculator over estimates, which is certainly better than underestimating. Why is the PSU company trying to convince him to get a cheaper PSU anyway? It's called honesty.

skrybe Posted April 17, 2014 Share Posted April 17, 2014 People have been overstating the requirements for PSUs for years now. I think some of that is a side effect of lousy brands where you had a heap of fluctuation - especially as you started ramping up the loads. So people bought bigger and bigger to reduce the stress on cheap components. I posted the draw on my system a few posts back. With a card that has a theoretical 250w draw I'm only seeing 280w for the whole system when artificially loading it up to test. Either Corsairs monitoring software is hugely inaccurate or 1200w is grossly overkill. That said, if you have the money and it gets you peace of mind then go nuts and buy the 1200. Just whichever you get, please come back and post the power use stats you see in CorsairLink here. Link to comment Share on other sites More sharing options...
skrybe Posted April 18, 2014 Share Posted April 18, 2014 Just a further update on this, there is a review of the new AMD 295x2 which includes power consumption. This is a beast of a setup they're testing, the GPU is actually a dual 290x put on one board, it's running a corsair cooling loop for the CPU and the GPU has it's own built in cooling loop. The GPU is rated as 500W (again, it's basically two 290x bolted together...) Their max system power consumption was under 700W in artifical testing (Furmark). Take a look here: http://www.anandtech.com/show/7930/the-amd-radeon-r9-295x2-review/17 For the record, they were using a Corsair 1200w PSU. :D Link to comment Share on other sites More sharing options...

Do you think so? now its either the ax860i, or evga p2 1000w oh and has pretty good reviews, http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story6&reid=361 Decisions, decisions...
