missed this.so you go to a two pin wall socket? Let's try your adapter. Do mobo only no gpus. Pass that test do one gpu Pass that test do two gpu Let us know if it Works with two. Then test with three, four, five, six .

Hello Late 4 the party i know, i just saw that.
6x RX480 uses more than 1200 W
that is a CONSUMER GRADE PSU, it is not a server grade
you should never EVER use a consumer grade PSU at more that 60% load capacity.
you should use 2 x 850W single rail, dual conversion (identical PSUs) with something like ADD2PSU gadget OR.... buy a 1700W PSU consumer grade.
even if you buy a server grade PSU, never use it over 80% load (continuous), at this point all bets are off.
i always use PSUs at 50% load rating, since 2013 i buy probably more than 300 PSUs for mining rigs, never EVER blow one of them, but i always load them at 50%, not more, need more power, use two in parallel with ADD2PSU (actually i made my own, it's freaking easy) more power?, add another one, if they are identical you can put three in paralell doing an add2psu gadget. (this is only possible if your psus are dual conversion, otherwise you will have a load of trouble)
and buy ONLY PSUs that are DUAL CONVERSION (that means that converts ALL power to 12V and then use separate VRM for 5v and 3.3v but the main transformer only produces 12V, so that you know that, if you don't use 5V and 3.3V you have all the power available for 12v rail)
another thing. first PSU in the rig powers all the risers, and the first two GPU (the one connected to the 16x primary slot) and the PC, the rest powers just the GPU 6/8 pin connectors.

Thanks for suggestions but as I already stated I was using modded bios and at most I loaded my PSU with 850 watts most.

okay lets see a link for the adapter as the adapter may be the cause of the short.
under small test load which passed you are fine. check 1
check 2 is a look see at the adapter.
check 3 is not to be done until check 2
It sucks but I have had cheap adapters kill psus and gear.
Once we figure out the adapter is good or get a better one
check 3 is plug the 24 pin into the mobo plug the cpu cable into the mobo using no cards boot and see if the mobo posts. this means you need to plug a video cable into the mobo's video
check 4 if check 3 passes put in 1 video card fire it up don't mine with it.
check 5 if check 4 passes test that same video card in all six slots don't mine with it
check 6 if check 5 passes test the same video card in all six slots via mining with it 1 hour each slot
check 7 if check 6 passes add a video card mine with 2 video cards for an hour.
check 8 if check 7 passes add a video card mine with 3 video cards for an hour.
check 9 if check 8 passes add a video card mine with 4 video cards for at least 2 hours
check 10 if check 9 passes add a video card mine with 5 video cards for at least 6 hours.
at this point if you have 5 working video cards you may as well stay at 5. going to six may not be worth it
I've carefully applied all steps and I'm glad to say that 6 gpu mining works well this time. Maybe I'll be adding more gpus if I can add a second psu. Thank you for your great help. For all others it is safe to say that 6 gpu mining on z87 deluxe quad is confirmed by me You need to disable following onboard features: integrated gpu wifi bluetooth thunderbolt realtek lan (maybe you can keep it active but you already have intel lan as well) I haven't tested this combination but maybe you can disable both lans and use wifi. In my test it has failed (while igpu was enabled).

you have insect or screw trapped inside your PSU, it happened to me

This is a good point. I once had an extra part in a psu it killed the mobo and the cpu

does the EVGA Supernova 1200p2 support - 6 rx480.
i have one rig with a 1200p2 running with 4 gpus. 2 more gpus are on the way.
do any of you guys have an EVGA 1200p2 running with 6 rx 480?
thanks

Yes it supports running 6 gpu but you should undervolt your gpus. I'm using Sapphire Nitro RX 480 models and each gpu pulls around 130 watts after using a modded bios and undervolt.

Is there any guide online i can find that will help me to do that. In future rigs i guess 2 psus would be a better option Which psu do you recommend for a 2 psu mining rig. Thanks

That is very good point. I only run my PSU at most 70% of the rated power.
