So I'm a little late to the party but have a few newbish questions I hope someone doesn't mind me answering. I've had a search on the forum and on google but can't seem to find the answer I'm looking for.

I have an Antminer S5, overclocked and draws 660w from the wall. Can I use a two dual PCI-E cable to power both boards? Or is 330W too much to put through a cable with 18AWG wire?

I've seen alot of people using the dual cables, but not sure if they're overclocking, underclocking etc, so thought it safer to ask the question before I have an accident.

The reason I ask is that I've been using my PC's PSU while a CX750M was on order. My computers PSU is semi modular so already had two PCI-E power cables already connected which I plugged into two of the inputs on the S5. I then connected up two extra pci-e power cables for the remaining two inputs on the S5. The PCI-E cables I have are 8 pin at the PSU end, and 6 at the other. The CX750M I have on order only has two 8 pin PCI-E sockets and four 6 pin PCI-E sockets. All my PCI-E cables have 8 pin connectors at one end, so it appears the only option at the moment is to use two dual 6 pin PCI-E cables. Or can I buy some cables to make use of the 6 pin sockets on the PSU?

Thanks in advance (newbie, be nice Roll Eyes)

your cx750m is a cosair correct?

it is a bronze and it is not too good.  I would not do what you did for a long list of reasons.

A) it is a bronze it burns a lot of power.
B) the cable issue you picked up on
C) lots of better deals available.

If it is too hard to return the cx750m plug in all four jacks and under clock to freq 275

run for a day check cables every hour or two.

then bump to freq 287.5 run for a day check cables every hour or two.

but like I said if it is easy to return return it as it is a poor choice to mine a s-5 with.
