New build suggestions

[Devin92]

Okay here is a build that I did for a friend

1. reason for i7 6700 + z170 mobo is the SLI capability. OC is not needed but my friend has his eye on SLI in the future so have to go for z170.

2. Question: if hes gonna do 1070 SLI will the 750W psu be enough or still a overkill? He most likely wont OC 1070 either.

3. Question: for utilizing the cuda cores, will SLI double the cuda core count? if not double, will it scale? or its the same story as GPU memory that certainly wont scale with SLI.

You can SLI with a H170 board. And get an AC adapter.

750watts are more than enough for two GTX 1070s.
I had two GTX 980s with an i7 on a 760watt PSU.

Bear in mind that very few boards support it, so make sure that they do.

There are actually no H170 boards at all that support SLI.
The only chipset that supports it is Z170.

Really? Wow, that's really dumb.

Yup, it kind of is.
It was the same with H97 boards.

Crossfire on the other hand is supported on H97 and H170.

I guess it all comes down to some deal between Intel and NVidia, so Intel can sell more Z chipsets.

Actually it's because how they work themselves fundamentally.

What do you mean?
I can't imagine why a H170 chipset shouldn't be able to support SLI.

Something to do with the PCIE lanes or something.

 

Quote

H170 drops some of this support. HSIO sees a reduction to 20 lanes from 26, limiting interface availability slightly. H170 also dips down to “just” 8 USB3.0 ports against Z170's 10USB3.0 ports, though both support 14 total USB ports. PCI-e lane allocation on the chipset is dropped from 20 lanes to 16 on H170, and the PCI-e configuration is limited to 1 x16 on a stock H170 board. This means that H170 will be generally incapable of supporting multi-GPU solutions. Note that the CPU itself hosts its own PCI-e lanes that can allow for multiple PCI-e slots on board, but these will be meant more for expansion cards than multiple graphics cards.

Not enough PCIE lanes for SLI:

so do you think a 650W good quality one would do? like RM650m or sth?

Yup.

Tom from OC3D did a little test a long time ago were he put a 780Ti and an i7 with a 450w PSU together. 

Total power draw was roughly at 400w.

Considering a 1070 is much more efficient than a 780Ti and that there was still a 250w gap until it would've hit 650,you should be fine.
