Hey Tim,
I Have a Z620 (smaller than a Z820) running with a TitanZ inside.
For such big card I had to convert both PCIe6 pins into 2 PCIe8 pins
connectors.
I did this after I ask to my official HP reseller, and he did confirm
that it wasn't a problem.
It's running fine here.

Regarding the HPZ820 and the 1100+W PSU, I would have hoped for a
better structured HP homepage, making it easier to find out if splitting
a 6pin into two 6 pin (or 6pin and 6pin+2 for a GTX980) would work
or stress the lane(s) beyond it´s limit.
The HP 8xx´s generally don´t provide dangling Molex connectors, btw.
There is loads and loads of information burried somewhere but what is
missing
is a simple button labeled CONTACT FOR INFORMATION.
I would want to ask, do you have a cable set for a HP8xx series PSU
that will
give me 4x6pin and if so, how much?
Those machines cost a couple of a thousand dollars/euros but it´s proven
easier to find gaming component related hardware&setup information in
the depths of the internet.
In conclusion, that´s why I wanted to share and point out that there
is a good
chance to run two GT970 cards (w/175W consumption each) using a clever
combination of a cable kit + an extra Y splitter but I wouldn´t want
to pull
loads of Watts trough the split 6pin connections either.
I´d think 2xGPU á la GT970 would be stable BUT
for a brute force level 4xGPU machine, I´d also look for another
mainboard+PSU+cooling+case
Anyway, personally, I´ll wait for a GTx9xxTI now...
Cheers,
tim

Damn premature sends! If you go molex to 6pin make sure it's with a
dual molex adapter, while good PSUs can deliver a lot more on them,
standard molex spec is 40W, while 6pin is 75W.

Splitting the outlet might or might not work out for you.
While it's touted as a feature a large majority of high
output PSUs are multirail because it's generally cheap to
provide multiple stable lines than one large pipe distributed
arbitrarily over N cables.
What that boils down to is that if you have an 800W CPU, but
it's a multirail with the 6pin on a 120W necked line (hard
coupled), and you fork it to two videocards for a 200W pull,
you are going at the very least to run a very hot PSU, and at
the worst to set it on fire :p
And if you think Dell or HP use premium components,
especially for the PSUs, think again, more often than not
even their workstation grade components have been, at one
point or another, extremely subpar.
You can always convert another rail if you have a multi rail.
6pins aren't anything magic, they still run two or three
sublines like anything else and a molex on a spare rail
should be convertible to 6pin. If you have a quality single
rail PSU, you should be able to safely split.

It´s good to write things like this, I guess.
A minute later I found the HP part number:
Hewlett Packard 6PIN TO DUAL-6PIN GRAPHICS ADAPTER
F5J05AA
This let´s you split a 6pin connection to 2x6pin.
--
Similar adapters are available from 3rd party vendors.
I can´t tell how well this would work when using "hot"
nVidia 7xx range cards
but the gt 970 cards are spec´d for needing roughly 150W,
drawing around 180W in
actual test scenarios.
--
I´d guess that would allow a stable 2xGPU system (using a
HP 1100+W PSU)
but for a 3-4xGPU system, I´d actually revert my
suggestion and go home/custom built.

There is a grain of salt.
Most if not all graphics cards come expecting an
additional 2x6pin power supply,
e.g. 75W from the PCIe slot, plus 75W from each 6pin
connection, there are
Quadro cards that are spec´ed for 150W power consumption
but most
gaming cards will excess that 150 W drain limit.
You´d need at least 4 6pin connections for 2 gaming cards.
The HP Z8++ series may present problems because of the
way the PSU provides
these 6 pin connections in a vendor specific cable kit.
There are several cable kits available but I haven´t
found a 4x6pin kit sofar.
This could be a dissapointment for anyone looking into
get such a plattform.
Of course, there is a chance I missed something from the
datasheets and spare parts
listings, as well as a chance the HPZ840 doesn´t have
such a limitation.
Worth mentioning anyway.

Worthwhile noting that Octane works with the GTX 9XX
cards very well. It also has a really good Network GPU
support. Which means you dont need to cram 4 cards into
one machine. If you dont know what you are doing the
machine can go *Poof* very easily.

Hi,
I would also like to recommend a nvidia gtx 9xx card,
the available cards
(970&980) have a lower power consumption compared to a
7xx series card.
Aside from that, I would like to point out nvidia CUDA
support, which might
help in a couple of programs, be it redshift or 3d coat
or the latest nvidia games
related tools (fluids, cloth, physics, etc for Maya).
If you have to invest now, e.g. immediately, I´d
suggest a 970 4GB card and
downloading a redshift demo to see if it would benefit
your workflow.
If you can wait a bit longer, I´d suggest waiting for a
successor to the 780ti or
Titan (Black) nvidia cards, expected early next year,
mostly because of the
more RAM expected to come with these cards, which would
give you more
headroom for heavy scene handling (e.g. shitloads
geometry and raytracing).
There is a lot of new stuff coming early next year,
including Houdini and Nuke
versions more accessible due to licensing changes/options.
In general, I would split my money between system RAM,
ssd and graphics unit,
expecting to work happy with a 128-256GB system OS
partition, 64GB ish RAM,
and a gt(x) 9xx ish card with at least 4GB VRAM (6-8GB
prefered).
Making sure that your system has a 800+ Watts PSU will
help stability.
>From there, finding redshift attractive, you could
always add another card to
your system, devoting it to getting more out of a
single render license or even
go fully committed and swap your mainboard to a
4x16PCIe version, adding
even more cards.
This implies a tower workstation case and enjoying
building your hardware.
Alternatively, I can recommend looking into refurbished
HP Z800/820 or Dell T7500/7600
workstations (on ebay) to get an idea about prices,
performance and extension options.
These plattforms are well enough documented to find a
solid, not to loud machine
that will reliable work 24/7 with a reasonably sized
PSU and at least a 2x16PCIe
graphics option.
There´s caveats with maximum system RAM or the PSU in
some of those refurbished machines
but they tend to be solid machines, well designed.
If all of the above is too much information for you:
Get a gt 970 card. They are the best bang for the buck
nvidia´s atm.
Cheers,
tim

right now 970 is best bang for backs.
they do not heat too much, power consumption

and on top of that Redshift as perfect

viewport performance is not that big issue
at all between two cards but being able to
utilise GPU rendering with CUDA is way more
higher on the list then couple more FPS in
viewport

The Redshift say go with the cards with
