Who to go with? (Nvidia partners?)

I'll personally wait for an EVGA AIO version. EVGA warranty and step up program are excellent.

from what i have read though only the founders card will be reference so if I want to fit a waterblock I will be best off getting the founders version or wait for a mainstream EVGA one.

Or have I read that wrong?

Here's the thing, though - the Founder's Edition only has a single 8-pin. If you're going to put it under water, where you could really max an overclock, it's likely to be a bottleneck.

Or it may not.

Something to look into, in any case.

just wait for 1080ti
you have no reason to upgrade sli980
let's be honest

Single 8 Pin = 150 Watts

PCI-E slot = 75 Watts

Total 225 Watts

Plenty for a card rated @180 Watts TDP

It is also possible to go over the figures above providing you are using a good PSU and motherboard.

Spot on.

Yeah I was aware that 225W was the total provided and 180W the card's stock TDP. So help me understand, I'll give you an example which will explain why I brought it up:

My 970 pulls 150W at stock. But overclocked (power limit 110 etc), it pulls 200W.

So, why wouldn't the max overclock on a 1080 be limited by having only 45W more to pull?

How did you find out your PSU power usage?

How did you find out your PSU power usage?

You mean GPU? Software to be fair (HWiNFO64), have not had chance to measure physically. Thing is that it accurately displays around 150W pull on stock, which matches the stock TDP, and then displays 200W when overclocked, which doesn't seem like a crazy figure. I'd love to measure physically to be double sure but don't have the equipment.

The figures I quoted are guidelines.

I also said that with a good quality motherboard and PSU you can pull more watts.

If Pascal is anything like Maxwell I would be very surprised if you get anywhere near 225 watts with a GTX 1080. Show a Maxwell card anymore than a tiny bit of extra voltage and all it does is get hot and crash.

I'd take those figures with a pinch of salt, software can be quite a way out.

But like Kaapstad has already said I doubt the 225 W limit will be a major problem. I'd also be surprised if at stock the 1080 uses anywhere near the TDP limit.

Thanks Kaap and Sasahara. Still need to wrap my head around some things but appreciate the responses.

I know software can't be trusted without comparing to a physical reading. In this case it does seem in line with multimeter readings though?

For this test, we measure the power consumption of only the graphics card via the PCI-Express power connector(s) and PCI-Express bus slot. A Keithley Integra 2700 digital multimeter with 6.5-digit resolution is used for all measurements. Again, the values here only reflect the card's power consumption as measured at its DC inputs, not that of the whole system.

Card Power Consumption - Maximum

MSI GTX 970 4GB - 213W
