Nice video! Just to say that one can get 470 Kh/s out of the Gigabyte R9-270 OC with
"thread-concurrency" : "15232",
"gpu-engine" : "1100",
"gpu-memclock" : "1500",
"gpu-threads" : "1",
Then, I'm a bit fed up on straight focus on power usage vs upfront cost here and there. At least on this video, the narrator explains all the concerns regarding power, cost, PSU stress, heat, instability. Well done, again, imho.

Thanks, glad you liked it - the channel is dedicated to all things cryptocurrency. Take a scan at our other videos!
As for your question...5 would be a stretch unless your running like 12 intensity which would only yield 500k/h a card. Based on my calculations you would be at best with undervolt: 275 + 275 + 225 + 225 + 225 = 1225 ...if its a gold/silver PSU you maybe able to get it done, just set those core clocks lower and dont OC. Hopefully you have a killowatt device and can check what your drawing, helps a ton!

Thanks for the awesome video!
I am about to set up 5 cards 4 of which are Gigabytes (x2 280x, x2 7950 WF3 F43) and one oddball sapphire 7950.
Was wondering if you think I would be able to get all these cards up and running on a 1200W Corsair with all of them being slightly undervolted.
I have another 750W PSU but was hoping I would be able to consolidate them all in one open air case with one PSU.
I was thinking I could get the 2 280x's on the 750W but that would be pushing it with the mobo/cpu, while the 1200W would be overkill for the x3 7950's.
Any help is appreciated, thanks again!
