I am in the process of selecting a graphics card for a second build project I'm working on and the narrowed down choice is currently between an Asus GTX780 Ti DCII or an Asus ROG Mars 760. I'm using the 780 in my primary build, so I'm pretty much sold on all its features - except the price (£550 approx in the UK). The Mars I can pick up for around £350 and I've heard some pretty good things about it, except power draw - nearly 480 Watts at full load. The PSU I'm planning to use is an AX760i, which should be OK with the 780 as I'm not planning on overclocking this rig. The other hardware on board is an i7 4770k, Maximus Hero VI mobo, Samsung SSD & WD 1Tb HDD, Corsair H100i and 5 Corsair SP120's - oh and Asus Blu-Ray drive. My question is, with all this gear, will the Mars work? Will there be enough power available or should I go with a higher PSU or the 100Watt lower (and £200 higher) 780Ti?

I would probably still go with a single card of some kind, just for the ability to upgrade down the road, as well as more VRAM. Either a 780 or 780Ti, or an r9 290/290x if you can find one around the price of a 780 or less. It will still give you great frame rates up to and including 2560x1440/2560x1600, and if you want to move to 4k at some point you can throw in another one and be ready to rock.

I've never been a huge fan of the whole 2 lower end GPU's instead of one higher end one. It's more complicated, games don't always scale (though they are getting better at that) and you limit your upgrade potential.

Thanks for this! The review here posts power consumption as nearly 60Watts lower under full load to what I was previously informed - I may have to keep looking in the reviews and forums for the moment. From this review, it seems like the PSU should be sufficient, but this is one review, another states that the conumption is much higher. I think I need to find an average before I make a full commitment.

Since the mars 760 is just dual 760s I believe I can help a little. I have a 760 myself so I have researched the power needed to run SLI 760s in case I upgrade and came to the conclusion that a good 750w psu will run two overclocked 760s in SLI with an over clocked i5/i7 just fine. Since the ax760i is one of the highest quality power supplies you can get it'll run the MARS 760 no problem.

Thank you both for your feedback - I think I'll make a commitment to the Mars. From the sounds of things, I should have enough power left over to do what I need. Worst case, I'll sell my last remaining kidney and purchase a higher PSU, but let's hope it doesn't come to that. Thank you again, I'll try and post something in the forums once I've set it up, just to let people know what the outcome is.

I have a 780Ti in my primary rig and I cannot recommend it enough; to say it's powerful is an understatement, but for the secondary, I'm trying to keep costs down, whilst still retaining optimal power. I could use just a standard 780 at roughly the same cost, but the Mars has really piqued my curiosity. I had an SLI rig a couple if years ago, with 2 x 570's, which were great for about 6 months, but with the draw on power being nearly 600Watts and the amazing 680 being released not long after, I never really had a chance to explore the SLI market. The Mars seems to address some of the things I'd like to test. My only regret is that for the short term I'll be using a single 1080p monitor, which isn't going to really test the capabilities of the Mars to its fullest, but I'll still be curious as to how it benchmarks - I'm especially keen to see if Nvidia's adaptive V-Sync is really necessary for this card and whether the upcoming G-Sync screens have any noticeable effect when using the Mars.
