Thanks for the info. I've gone ahead with the breakout board and Dell PowerEdge 750w.

So far, I've found someone who can get me a server power supply (Dell PowerEdge 750w)

With a bit of research, I found this and found out I can get this down in Australia with the 4x PCIe cables.

I have experience with messing around with electronic so this isn't too new to me to put together, but I'm wondering if a 750w server power supply will be enough at least 2 Antminer S3s. If it is I can get this all together for around 80 bucks which would be so much better than spending ~$150 and still be skimping on the power

Hmmmm.... So atm, I've got 2 S3s. Could I power the both of them with 1 power supply?? A Cougar CMX 850w power supply to be exact.
The reviews for the power supply look good and its got 4 PCI-e connectors.
What do you reckon??
Or do I just stick with 2 Corsair VS 550s
Sometime in the future I'll possibly have a Antminer C1 as well.

I'm a complete noob at mining with ASIC miners. I'm transitioning from GPU mining. What powersupply is best to use?

I've seen these:
