80% tdp, consumption is not that far away, the trick is to reduce memory to -502 for another boost, and core you can even do only 50 or 100, not really necessary

I have not seen 14AWG on ebay, but just checked a boxes from original 1080ti's and the ones that came with splitter cables are all 16AWG, so i would assume its safe to use 16awg, also apparently majority of breakout boards for server supplies are using 16awg cables as i can see.

Per your link to ebay 2400W supply yes, that one and this is ibm blade H series one (250A on 12V rail):
http://www.ebay.com/itm/39Y7364-IBM-Corporation-FRU-BladeCenter-H-2900-w-power-supply-w-fan-unit-/252945697056?hash=item3ae4bd0920:g:HyoAAOSwaEhZHhlI  there is a breakout cable available for it too.

I know but I can't find them any place id rather use 14AWG wire,:)  you got a link to some made, i hate making my own ...and if the link i posted was 20AWG or higher i wouldn't have link it or said don't buy them because 20 AWG wire or higher is unsafe to use for mining rigs that was mostly a example of what to look for .

but if you know someone that sells the 14AWG wire splitters ?. i would buy a few .ID even go for 12AWG wire which would be over kill and cost a lot I'm sure . I run at default/stock setting on all my cards so shouldn't 18  be ok for 470 and 480 but i want 14AWG wire splitters, just can't find them, if they even exist for public sell.

and if you mean this server PSU

They are very quite  I hear the miner over them i was very amazed at how quite they are i expected them to be just how you said i own two and buying two more in time ..NO kidding on the noise part ...

I use one to power a Alchemist 256 with five fully working boards, all i hear is the miner, and i have replaced most of the fans on the miner to quite it down and use a siding windows fan at max speed blowing down on the miner and it works .... and @ about 1500 watts usage from five boards, no noise what so ever form the PSU. @ max for the PSU  can't say but if there is no noise at 1500 usages it should be ok at 2300 watts or @ max use .


ID move them to open air frames that should take care of a lot of the heat , i had two cards in a reg PC case and the heat was bad till I moved to open air frames now it ranges from 49 C to 62 C per card depending how bad the cooling on the card is at about 80 % fan speed per card . @ stock settings for two four card rigs.

I buy what ever card is the cheapest when i buy one most of the time with a rebate and don't care much about them being the same brand AMD card they All run the same to me and got some nice deals for RX 480 at RX 470 prices without using the rebate with the rebate even cheater ....I guess you would say i was at the right place at the time for those 480s.

 I just started building my third open air four card rig.

definitely, but since I have density issues I need the highest hash power available so they are what's best for me atm - wanting to add more but I'm running out of breakers to throw the machines on... oh... and the heat... the heat! lol I've been reading for a couple days now trying to find proper cooling solutions - all my rigs (not really rigs, just computers 2 GPU each) are currently looking waaaaaaay bulky since they're all in Full Tower cases

yes, stock tdp is absurd and specially for gigabyte now im on 73% tdp and eats only 180w founders ed.

Some folks here said, that molex plug raisers are often not working properly...have not used those myself but...
also there are some raisers with additional caps 270mkF some with 150mkF, i would go with bigger caps and powered ones, who knows what kind of cards will be next gen and what power requirements will be, so for the upgrade sake, i take powered ones.
 Server supplies are nothing extraordinary and no need to be guru to use them, the main difference is that they ARE louder, there are some people here who sell those in 1200w/1500w HP/DELL branded, with or without breakout board/cables.
Also ebay has some 2400W server PSU for ASICs that are basically HP/DELL OR 3000W IBM blade H series, but its huge and i bet it whines like F1 engine.

today is was messing with 2x1080ti - msi extreme oc and gigabyte xtreme oc versions - on stock clocks, with core2duo/8gb ddr2 ram/500gb hdd 7200 and about 5x120mm fans - at the wall, when mining, thing eats 680-720Watts (under 75'C) being said that, having powered raisers is plus, sa apparently those versions consume about 300W each at least and they have 8pin +8pin connector on each card (150w+150w)ave 18AWG

@Toptek
- those splitters have 18awg wire, according to Ampacity Table http://www.stayonline.com/reference-circuit-ampacity.aspx it can handle 7-10amps which is below 150W (P=UI  / POWER=VOLTAGE*CURRENT) so net step would be 16awg which is ok... but it is recommended to have those 4PIN PCIE splitters with 14AWG wire.

Why do the risers have to be powered I'm curious?

The 1080Ti's already need to use 1 8Pin and 1 6 Pin cable - I didn't think that the riser needed power as well

why not buy these type http://www.ebay.com/itm/252953003440?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT  Risers
and then spit them with one pci plug per card with this http://www.ebay.com/itm/361651807884?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

some one made a good point in another thread the other day about how much safer it is to do it that way so, i did it and so far it seems the two rigs i have so far, run better and each card  and risers has it own PCI plug powering it ... from the PCI plug off the PSU and next thing,I'm gonna do is start using SERVER PSUs once i learn more on how to and either buy or put to gather one or two kits, so i can use server psu's ,,,

How long have you been running 1080Ti's on the risers you listed, and zero issues with them? How many do you have running?

Would like to hear from someone that's got them running, wouldn't want to burn the house down lol
Thanks.

I wouldn't go with those, I'd rather go with powered risers. Atleast from my experience these work much better.

hmmmm settings of gpu? and its FE too?

I'm only getting 800-850 depending on card but 8 different 1080TI's on 70% +200 +225 and they all just hover around 800 - what settings are you using? Thanks Vaccinus

you can do 950 on skeina nd i think 1000 with some heavy oc, but i found that 950 is the sweet spot, to have nice consumption and not overheat, because now in summer it's better to not push too far your gpu

this will be longer conversation

im owner of asus 1080ti fe (bought for my gaming rig but due to insanse coil whine is able only mining) and its realy REALY beast ... (180watts on skein algo 880MH/s)

4x1070 evga sc black ed. arriwed today (HOOORAAAAY) BUT waiting for risers damn ....

risers ordered: http://www.dx.com/p/kitbon-usb-3-0-pci-e-1x-to-16x-riser-adapter-card-extender-cable-465573

im planing to make a rig with 7 gpus in total (2x1080ti + 5x1070, but dont have money for the rest of cards and 7x 1080ti is toooo expensive for me) on asus z170 pro gaming (was in my gaming pc, rma`ed, meanwhile bought asus z170-p, so now is in free for mining ... it has 3+3 pcie + m.2) and then lets see

m.2 to pcie4x card: https://www.aliexpress.com/store/product/Free-shipping-NGFF-to-PCI-e-4x-Slot-Riser-Card-M-key-M-2-SSD-Port/623732_32248406559.html

as mentioned ... 1080ti dont need powered riser, but it can be pluged into it? ... but i "need" length of usb cables, so there is no other way, coz there is no longer non-powered riser then +-200mm and i think its too short for placing in rig im building (own construction, alluminium plate, 2x psu)

So something like these should be just fine since I have to use 1x8Pin and 1x6Pin on the card:

Thanks.

i have also 1 1080ti the palit super jetstream, it's really a great beast it feel like a mini asic in my case lol, and yes there is no psu that come with so many 2x8 pin all at once you need to buy those on another store, and they are hard to get, this if you are going to build your 6 x gpu rig

Thanks - yeah they definitely are beast ... I threw these

https://s12.postimg.org/fhsw41v8t/tis.jpg

into 5 dual rigs last night, been up all night playing with them.

Such a PITA finding not 1 but TWO freaking 8 pin ports on each PSU lol.

My EVGA 1500 has I think 8 so it will support 4 cards at least

Time to place the order for the risers now, more Ti's are already en route

the 1080ti don't need anything more than unpowered risers because it come with 2x 8 pin, which deliver 300 watt, and 300watt are more than enough to power this beast

Just trying to see who has some really reliable quality risers - hawk doesn't seem to have any in stock atm

Will be for 1080 ti's if that even matters
