CX750 is perfectly fine for OC S3 and better option than the CX750M for an OC S3 IMO.
4 SEPERATE PCI-E connections = CX750
2 SEPERATE PCI-E CONNECTIONS = C750M
I am OC S3@225 on both CX750 and CX750M though. Cables on M with 4 connection to S3 are still totally cool to touch in my environment. Still wish I had bought only CX750 now that I have S3's on them instead of S1's

Is there anyone here that can post what PSU they have and if its powering an overclocked antminer s3?
I am a dumb girl that can't figure out this whole PSU situation
I can't choose between a CX500, CX600 or CX750 per antminer.
The cost between those power supplies are quite a bit for me.
HELP!

WHAT CONFUSES ME IS THAT SOME PEOPLE SAY I SHOULD GET A PSU WITH 4 SEPERATE PCI-E connections.
SOME PEOPLE SAY THE ANTMINER S3 will overclock well on 2 SEPERATE PCI-E CONNECTIONS.

I can't choose!

JennaK, I am using a CX750 with the 4 PCI-E connected.
Was able to overclock to 250 and get more hashing but the temperature goes high 4 degrees in each board so I went back to 218.75 to avoid burning it before get my ROI.

See this is exactly what I'm talking about, none of this is making any sense. Everyone is strongly suggesting using 4 pcie connectors instead of 2, yet they then give the above example.

In the above example, they might as well be using two pcie connectors instead of four. I have 2 cx750s, they have two double pcie connectors. Just because they have two pcie connectors on one pcie cable does not two pcie cables make. Those two pcie connectors are going to be heating up that one pcie wire just as much as if you plugged in one of the connectors. So yeah, you now have 4 pcie plugs but the temps are the same as two pcie plugs. Am I missing something?

Under the above example I would need 2 cx750s to power one overclocked antminer.

There is no sense in asking these PSU questions again and again.
A lot of times here explained how to size the power supply for any device by your own.
Its as simple as driving a glass of chilled beer. Its not a rocket science.
I'm writing a thread on how to size psu for any miner and will post the link here soon.

Here is my DIY thread for sizing/finding a Power Supply for S3 or any other dc device.
