fretman Posted January 17, 2016 Share Posted January 17, 2016 Hi, Just got the Corsair CX430M. On the power supply unit, there is a connection labelled 6+2 PCI-E and 4+4 CPU. I am sure that the cable for my PCI-E goes into there. But what is the 4+4 CPU all about. Is that just a labelling mistake? Thanks. Link to comment Share on other sites More sharing options...
UsernameTaken Posted January 17, 2016 Share Posted January 17, 2016 The 4x4 CPU connector (Or more commonly the EPS +12V connector) is one that is mandatory to plug in. The PCI-E cables plug into your PCI-E devices (GPUs, etc.). And no, it's not a labeling mistake. The 4x4 connector is located above the VRM of the motherboard toward the IO. Edit: The CX430M has the 'EPS' connector plugged in by default (non-modular). This signifies that the user (you) must plug the cable in. Link to comment Share on other sites More sharing options...
ConfusedGamer Posted January 17, 2016 Share Posted January 17, 2016 Fwiw, I've just had this exact same issue on a CS550M. It's essentially a dual purpose port. You shoulld have a cable with a 'Type 3' connector at the PSU end and two 6+2 PCI-E connectors at the other. That's the one to run a GPU off from that port.

fretman Posted January 18, 2016 Author Share Posted January 18, 2016 'tMaybe my post wasn't very clear. Take a like at this picture: http://ep.yimg.com/ay/directron/corsair-cx430m-cx-series-atx12v-eps12v-430w-modular-power-supply-cp-9020058-na-80-plus-bronze-certified-active-pfc-1.gif I'm asking why Corsair has a 4+4 CPU connector port there if the modular cable they provide is for a PCI-E connection. Because once that port fills up, you can't use it for a second CPU connection provided your mobo has 2 CPU sockets. Link to comment Share on other sites More sharing options...
red-ray Posted January 18, 2016 Share Posted January 18, 2016 The 6+2 PCI-E & 4+4 CPU output can be used either to power a graphics card or the 2nd CPU in a dual socket system by using the appropriate one of two different cables. The PSU may only come with the 6+2 PCI-E cable, but you could buy the 4+4 CPU cable. Link to comment Share on other sites More sharing options...
fretman Posted January 18, 2016 Author Share Posted January 18, 2016 So in other words, if I have a setup with a PCI-E graphics card and a mobo that requires 2 CPU powered connections, then this PSU would not provide me that connection? Correct? I can have one but not the other??? Link to comment Share on other sites More sharing options...

Correct? I can have one but not the other??? Yes, that is correct. I further expect most dual socket systems with a PCI-E powered graphics card will need more than 430 watts of power.

But it's only an entry level 430W PSU, so I'm not sure what you're actually expecting. :confused: Link to comment Share on other sites More sharing options...
fretman Posted January 18, 2016 Author Share Posted January 18, 2016 Yes... But it's only an entry level 430W PSU, so I'm not sure what you're actually expecting. :confused: Wasn't expecting anything...was just curious to see why Corsair labelled their PSU with 4+2 PCI-E and 4+4 CPU when you can only use one or the other. I think Red-Ray cleared things up. Thanks to everyone for their assistance. This thread can be closed now. Link to comment Share on other sites More sharing options...
