Should probably look more at important things like... Max wattage Efficiency rating Number of rails Amperage of each rail More important than brand names and prices. Asking best brand and price is gonna get you 50 different opinions from 50 different people  |

Probably more than one. For 2X5870 X-Series 650W should be enough. For 2X5970, 850W. |

Asking best brand and price is gonna get you 50 different opinions from 50 different people I would actually look more at the continuous wattage, max wattage isn't sustainable in most cases and the number of rails doesn't matter... |

Can a PSU straddle more than one machine? Say you have two boxes with 4 cards each. Could you stick a 600-700 on each mobo and then set up a third PSU to feed some of the cards off of each mobo?

Yep, that's possible. There's actually supplemental PSU's they sell made just to juice graphics cards and processors. Some even fit in a 5.25" drive bay. |

Efficiency wise I would recommend
1. Seasonic X (80+gold)
2. Corsair A (80+gold
3. Silverstone Strider + (80+ silver or gold)
Though they do come at a price premium, but I use those for most of my work units.
I don't mind running a few crappy miners either since they cost next to nothing. Using basic 300W Fortron/FSP psu's they run 24/7 just fine since last Sept.,, although incur higher electricity costs and are less efficient.
And they are practically limited to 5850s and 5770s so no efficient dual gpu setups possible.

I recommend an Antec 1200 High Current Pro, I have used one and ran 1800W (measured wall draw) continuously for weeks with no problems. I have also seen where the rating has been exceeded for up to 2100Watts and the PSU still held together! |

The asus Rampage III Extreme, Maximus III Extreme, and Croshair 4 extreme are all very reliable and comparable. they were designed for 4 GPU solutions and dont need any PCIe cables or converters. For an external cooling system that will scale with larger systems and multiple systems Koolance has some rackmount solutions http://www.koolance.com/water-cooling/product_info.php?product_id=1173 |
