CPU 4+4 vs GPU 6+2 connectors

Mr_Cynical · 1 Oct 2014 at 17:52

The PSU I'm using for my build is a Corsair RM650. The back panel has (other than the usual SATA/ATX slots) three identical-looking slots and simply labelled "6+2 PCI-E & 4+4 CPU". There's an image here if my description is a bit useless!

Am I correct in thinking that these three are interchangeable? I assume from the label that they should be, but I'm aware that if they aren't interchangeable it would be a Very Bad Thing to plug the CPU power cable into what the PSU intends as a GPU slot, or vice-versa!

Looks like they are interchangeable to me. There's nowhere else to plug them into anyway. Not seen it done like that on a psu before as they usually have different connectors and dedicated sockets.

That PSU has a single 54A +12v Rail, so make sense for them to be interchangeable - specific sockets are normally used on PSUs that have multiple rails e.g. to put CPU on Rail1, GPU1 on Rail2, GPU3 on Rail3.

My current psu is single rail as was the one before that and both have specific sockets where you have to plug in the leads.

I just fitted a new AX1500i last night and had the exact same dilemma. Albeit a brief one.

In the end I just thought it makes sense when you consider its a single 12v rail. Anyway hooked it and no problems, so just choose any 12v socket and you should be fine.

The layout principally on my AX1550i is the same as yours only far more sockets within the given category as you'd expect. The plug philosophy is the same and I was fine.

EDIT: just noticed the age of the op. I reckon we'd know by now if it had gone pop!
