What's wrong with 80plus Gold?

I could definitely see myself upgrading to SLI in 1-2 years so I think going with the 850w might be a good option. Is there any disadvantage to having a larger power supply then needed though if I never got around to upgrading?
 
Is there a disadvantage? No. There's just too many people who think getting an 80+ Platinum 1500w PSU will increase performance or something lol power supplies first and foremost need to be quality built. Wattage is important, yes, but seeing as though the system you have up there will only pull around 375w at peak load when overclocked (http://www.anandtech.com/show/7492/the-geforce-gtx-780-ti-review/15) you wanted to make sure you get a a quality unit that is able to last.

The EVGA 750w Supernova is ok, but it uses lower quality capacitors and just isn't as well-built. If being put into a $750 system, it's fine, but the PSU is the most important part to a build, and you don't want a high-end system running on a lower end power supply. That'd be like running a Ferrari on regular 87 octane lol

Surely if you're planning to SLI in a few years time it would be best to purchase a new PSU then? That way you are using a brand new, higher quality PSU rather than one that's already been in use for a few years.
 
In a year or two the 850w XFX I listed above won't be nearly deprecated enough to warrant buying an entirely new power supply. It comes with a 5-year warranty from XFX for a reason. They build that model to last, and it is warranted for 5 years to be able to supply at least 850w of total output.

If he was putting in the 750w Supernova, or a similar power supply, then I would recommend upgrading the power supply then, but with top-of-the-line units, you don't need to do that.

Alright I will definitely be going with the 850w XFX then. I really appreciate all the help and the explanation!

There is no direct disadvatge of having a massive PSU but in lower end build you don't have to completely overkill your PSU because with a small power draw out of a massive low quality PSU it is possible to get below the sweetspot for that particualr PSU which is ually just above half of it's theorethical maximum output. This can actually results in more power draw than with a smaller PSU.

With a build of your caliber, this is not a problem and you should focus on cost instead.
