Ok so im ordering my new pc soon and have decided on what i want

Will that motherboard be able to run Tri Sli? and will i need 1000w because i will be adding a Cpu and both gpu wc loop later early next year?
 
the ram a poor choice buy 1600 mhz ram at minimum.

To go with your case

Kingston beast 2133mhz

The board can run tri-sli but at reduced speeds for the 3rd card making it not worth doing IMHO

Expansion Slots
- 2 x PCI Express 3.0/2.0 x16 slots (Single at x16, Dual at x8/x8)
- 1 x PCI Express 2.0 x16 slot* [black] (Max. at x4 mode, compatible with PCIe x1 and x4 devices)

The 1000 should cope with duel sli but not with tri sli. The 780 draws just under 300 watts at standard speeds so tri-sli (for what its worth) would be very close to the max of the psu.

Not to rain on your advice.

But the board wont do Tri-SLI as you need at least 8X on a slot to get validation from Nvidia.

It will do 3way Crossfire ok.

X79 and Z87 boards with a PLX chip will support 3+4way SLI.
 
I would just like to ask the question as to why do you want to go Tri-SLI, you know that 90% of games do not actually scale well pass two way SLI?. You only really see these kind of system pull ahead when your benchmarking with something like 3D Mark or Unigene.....
 
joeyjoj: really? i have that psu and was worried about changing my single gtx570 to a single gtx780 since it's only 650w. Could i run my 570 AND the 780?

I'm just going on the reported numbers (544 W peak for 2x 780s + 3960X @ 4.6), but I forgot to mention that if overclocking the graphics then you should bump that up to around 800 W. I would personally go for less though (more efficient and cba to overclock GPUs).

The 570 consumes a similar amount of power to the 780 (a bit less actually) so yep I suppose it's the same advice...

Im not too bothered about tri to be fair i'd just like the option available later on if games ever start scaling

2011 is for the -E chips, i.e. no integrated graphics and six core options (the chip you've got is 4 though).

Still I'd get an 800 W PSU, 1250 is silly and you'll never need it. e.g. this very efficient one.

Seasonic 860w '80 Plus Platinum' Modular Power Supply £179.99

 
It's up to the thread starter really, but it seems to me that buying a 400 W overspec'ed PSU "just in case" is a waste of power and money. I'd save the £20 and get a platinum rated PSU which can do the job at hand.

It depends on how likely he is to buy a third 780 in the future. My bet is not very likely. By the time he needs three GPUs there'll be faster single cards (unless he plays at ridonculous resolutions).

I've decided that ill ditch getting 3 cards and get a sound card or something along those lines, so a decent 850w platinum psu will be what i need?
