PSU Question for SLI

I will eventually want to SLI 980 Ti and this is my current build. Are there certain PSU's for SLI? Any recommendations for my current build?

We can't see your build.

Regardless, so long as the PSU has sufficient output and enough PCIe cables, you should be fine. Granted, with something that expensive, you also want a very high-quality PSU, but you can theoretically SLI with any junker of a PSU which can deliver the requisite power via the requisite cables.

Alrighty.

You're perfectly fine. EVGA G2 is superb, and 850W should be enough, although I'd be a bit careful about overclocking.

Of course, I tend to be more careful than most about how much wattage is needed.

I will make sure I check my wattage before I do something like that. Thanks.

A heavily overclocked 5820k draws around 60w above its TDP, which would put your system wattage at 820w worst case at full load. In SLI, the second GPU doesn't consume the full rate of power, so you'll be safe.

It's also worth noting that for a 5820k to overclock to a 60w delta, it requires heavy liquid cooling. So you should definitely be safe.

Should I do liquid cooling then?

Anywhere from 850-1200W should be fine depending on the rest of your build and how far you plan to OC

Antec High Current Gamer PSU at 850W is only $69.99 right now and a steal.

The primary reason to buy a gold rated PSU is for quietness. Higher efficiency devices will be less likely to need to run the cooling fan at high rpm. You are unlikely to recoup any price premium from electricity savings.

tell that to people who bought the 1000 G2/1300 G2 and a bunch of other really loud 80+ gold psus I could name. psu noise level depends on the fan type, fan size, grill type, most importantly, the fan profile setting. efficiency and capacity have little to do with it.

Well obviously the more wattage available/utilized, the louder the unit will be. Noise and heat are the byproducts of having more power.

I was talking about comparing 850W bronze with 850W gold... not 500W bronze with 1000W gold.

At $69.99 for a reliable semi-modular 850 Watt unit, I don't see much reason to complain.

EVGA and XFX are the next best units at nearly $100... both Bronze rated by the way.

Edit: I almost missed this one. It is a great buy for your argument and fully modular: https://pcpartpicker.com/part/seasonic-power-supply-x850
