...and for sure you cannot use just one 1000w PSU for 5 or more cards

Yes you can. Tuned RX series graphics cards (ie undervolted and underclocked) consume much less power. Max would be ~140w if you also account for GDDR5 at the most extreme timing and clock adjustment.
5 or 6 GPUs are quite possible (and considerably safe) on 1000w. Just as long as everything else is low power and the PSU is really high quality, such as a Supernova P2, Seasonic, Super Flower etc.

I'd argue that 6 GPUs on a 1000W power supply isnt that safe. The PSU would be on higher than 80% load and it is not recommended for a configuration that is going to be ON for 24/7

I've done it 95% load and it's safe if the PSU is good quality. It's not efficient and not recommended, you'll get good efficiency and longer life span of PSU at 80% load.

Could you recommend me some other PSU that can run 6 cards with efficiency?

An quality 80+ Platinum from companies such as EVGA,Seasonic and Super Flower would be fine. user evakka refers it as not efficient because is a curve that indicates how efficient the PSU is according to its load.
For example an 80+ Platinum rated power supply should be 90% efficient at 20% load, 92% at 50% and 89% at 100% load. So a EVGA superNOVA P2 1000W that supplies 6 GPUs of a maximum 140W will be on worst case scenario at 84% load. If you remove one you might save more money in the long term.

how about 1300W G2? would it be efficent enough to run 6? it is less than $100 difference so wouldnt it be worth investment for 6th card?

Yeah I guess that would be really efficient to say the least. 64% load sounds neat and might be more efficient than a 1000W Platinum PSU running at 84% load. So go for it.

With 10 years warranty, I wouldn't worry that much.

For OP:
Yes, you can use your integrated GPU for regular tasks like browsing and watching streams etc. Just plug the monitor into the integrated GPU and you're all set. If you have AMD cards mining, you'll still need a monitor or dummy plugged in to one of the AMD cards or they won't be able to be overclocked in Windows. Nvidia does not need a dummy plug.

My daughter's PC has two RX 470 in it and is using the integrated GPU to the monitor since all she does is play Roblox and watch Youtube and the integrated one is enough for that. If her monitor is plugged into one of the AMD cards, it'll all start to lag - even Netflix. But since the integrated GPU isn't used for mining, it works great with that.

Is it really possible to use integrated GPU along side with 6 external GPUs? Thats the most important aspect for me. I do not want to sacrifice a card/power for my regular tasks. I am hearing some people saying it won't work when external GPUs are intalled though.. Sad

I have two rigs, one contains 7 gpus and dual psu config (1200 P2 and second psu), other 4 cards. I'm using 4 cards rig as daily pc to play games, browse internet etc.

It works pretty good, but I've one concern about FPS games. I play CS Go and I use all cards for mining. I use onboard gpu of i7 4790k for gaming. Of course graphics are bad. I've used one of the gpus instead of onboard gpu, but noticed micro stutters/lags during combat.

Besides, my wireless keyboard sometimes get locked (I'm unable to move my character using kb) but I can fire and look around using mouse.

I'd like to know if anyone else have similar issues? I'm wondering if switching to wired keyboard will resolve this issue.

That would be true if all GPUs were constantly drawing 140w of power. That's a theoretical maximum though just to be safe if there are any peaks.
Due to scaling the total draw will be slightly less and depending on how each GPU is configured, power draw could be slightly less for each card, moderately reducing total draw and bringing the load percentage well below 80. Plus the EVGA G3 is a very high-quality PSU so OP will have absolutely no issues.

Sounds like you know what you're talking about i've been quite absent from the PC world, looks like I learned something today

Using a mining rig for a fully functional pc/workstation is actually very possible.
You will certainly want to increase your ram from 8 gigs to minimum 16 but more is even better.
Consider running your mining system on a vm if using windows as main OS or simply do some pid priority work if using linux.
