Hi,

I'm considering getting a second one of these cards as I can pick it up cheap, however I currently have an 860W PSU and was wondering if that'd be sufficient or if I'd need to upgrade it?

I did have a look online but couldn't find any conclusive information.

PSU: Corsair AX860, Platinum efficiency.

Rest of your build ?

This calculator says you consume 544Watts with i7 4770k, 4 hard drives, high end mobo, titan black (only one) and one DVD. If thats the case, I am pretty much sure that the rest 300W will be enough.

I don`t really trust every calculator and if you want to hear "my own opinion".

YES, It WILL be enough. Your CPU consumes max 100w (if i7 haswell) and GPUS consume 500w together.

EDIT: Agreed with the above guy.

GO FOR IT !

it would work but you would be pushing it i would get a better PSU just to be safe

you would use around (not overclocked) about 850W with both cards so you should have a 1000W+

This is what worries me, conflicting opinions! I ran the calculator with my full build and the result was 760W @ 100% load.

Eh, I can see you have a nice overclock there and fancy stuff like watercooling that might consume power.

Spoiler
Fancy for entry level folks like me anyway :D 


Without any overclock i7 has 84w TDP.

2 TITANS have 500 watt TDP.

500+84=584 860-584=276

You have 276 watts left for your overclocking and other stuff.

Seems enough to me if you dont overclock like crazy dude who is trying to fly using toilet paper :lol:

I don't use any water cooling, just a Phanteks air cooler that uses two 140mm fans.

Haha no worries.

So with regard to the power requirement of the GPU, because they are "Superclocked" cards by EVGA will they not need more power?

Maybe but TDP is generally high enough. Nvidia leaves enough space for manufacturers to OC.

Looking to it from the EVGA site. :) 

EDIT: Here it says minimum 600W with 504 Watts on the 12V for SINGLE card.

EDIT2: Even if your setup use 600 watts on single card, lets say GPU consumes 300 watt and CPU 150, other things 150, You will have 260 for other card. And it will never happen because you would need to run everything on max.

I had a look at that but there's no info for SLI.

Like I said, I really don`t think you will hit 800. What res are you playing at? I mean, there is no way that everything will run on max, consume that much, and will not leave any wattage left.

Its crazy :kaola:

Only at 1080p at the moment but plan to upgrade my monitor if I upgrade to the second card.

Well, my opinion is that. If you don`t have an REALLY ULTRA SUPER UBER MEGA overclock running and you don`t torture test your PC with uh, GPU CPU and all the stuff consuming %100 power at the same time, I don`t think 860 watts will be a problem, ever :) 

And is your GPU O.C.ed ?

Factory OC'd. Not sure whether I'd want to OC them even more.

Overclock all you want. The AX860 is a rebranded Seasonic Platinum unit making it among the best on the market. It provides a full 71 amps on the 12v rail.

Look here. Their test system is listed as:


•Intel Core i5 3570K (operating at 4.2GHz – 42 x 100MHz)
•Asus Maximus V Extreme motherboard
•2 x 4GB Corsair 2,400MHz DDR3 memory
•Lepa G1600 1600W PSU
•Windows 7 Home Premium 64bit
•Samsung SSD 830 256GB SSD

At max draw they are pulling 384 watts. Even adding in another full 250 watts for a second card you will never pull over 630 watts. That gives you an optimal 200-250 watts headroom.

Thanks to everyone who has helped, but you Sir, will get best answer.

Thanks again to all.

Gonna order the second card next month. Not long to wait now!!!
