(1 full machine & 'in-window' twin cooling fan per circuit, 3rd rig split over 2 circuits to keep from blowing breaker)
Circuit A also has a Dell 24port 10/100 switch (almost forgot about that...lol
All cards running @ 950Mhz GPU / 900Mhz Mem @ 1.02V, 565MH/s per card....(using CGMiner 2.4.1 defaults, Win7 x64)
Both of the remaining 4-card rigs will also get their 5th 7970's installed as soon as the cards arrive.
Hope this helps some people, or gives a few ideas for those wondering....
For those wondering about specific setup...(not including the obvious single power supply 5-card/1200W PSU Rig)...
On the 2x PSU rigs, I use the 850's to power the Motherboard/CPU/HDD + 2 Video Card's External 8pin/6pin connectors (and of course all PCIe Slot Power by association).
The Secondary 650's get used for external Video Card power to the 6pin/8pin connectors to the 3rd, 4th and 5th cards (and perhaps additional cooling fans if required in the future).
