hey folks,

I've been looking around for a power supply suitable for overclocking a single unit. I will run the unit stock for a time, then oc it sometime later. I would like a power supply suitable for both modes of operation. So far, I find plenty of 2x pcie units, but very few 4x pcie units (ive been told oc'ing requires all 4 pcie cables to be connected.) Can someone please point me to a suitable product that has 4 pcie connectors for ocing (or point me to a unit that can do it with two cables)? It would be greatly appreciated, this has caused me a great deal of confusion. Pardon if this has been covered before.

I oc'ed one of my units using only 2 cables and is doing 500Gh/s happily. Others have reported issues with using 4 cables and the way I look at it is, the S1 only uses 2 cables and they draw more power so it should be a non-issue.

The issue is what your wires handle. Using 2 seperate 6pins is different than using 1 cable with 2 6pins on the end.

3 pairs of quality 18 gauge wires (typical PCIe cable) will easily handle the ~16A of 12V power consumed by an S3 at 450Mhz, whether to 1 connector or 2.
